THE SELECTION PROCESS
YOU NEED THE RIGHT RIG TO GET THE JOB DONE RIGHT.
CAUTION
It takes the right truck to give you the specific trailering capabilities you need.
A number of factors must be taken into account — everything from the weight of
the load to driving conditions. This document will assist you in selecting the
vehicle, powertrain and other equipment that best suit your particular application.
If you don’t use the correct equipment and drive properly, you can lose control of
your vehicle when you pull a trailer. For example, if the trailer is too heavy, your
vehicle’s brakes may not work well — if at all. Your vehicle passengers and you
could also be seriously injured. Pull a trailer only after you have taken the following
precautions. Trailer Brakes — If your trailer weighs more than 454 kg (1000 lb.)*
loaded, then it must have its own adequate brakes. Be sure to read and follow the
instructions for the trailer brake controller so that it is installed, adjusted and
maintained properly. Hitches — It’s important to have the correct hitch equipment.
Crosswinds, large trucks going by and rough roads are just a few of the reasons
why you’ll need the right hitch. Be sure to use a frame-mounted, weight-distributing
hitch and sway control of the proper size if the loaded trailer will weigh more
than the limit shown for a weight-carrying hitch in the specific vehicle notes.
This equipment is very important for proper vehicle weight distribution and
good handling.
Note: These safety steps are by no means the only precautions to be taken when
trailering. See your vehicle Owner’s Manual for additional information.
You should look for the same qualities in a tow vehicle that you do in any truck —
you need it to be strong and powerful, as well as comfortable and accommodating.
That’s what makes Chevrolet trucks such a smart choice for trailering. Chevy trucks
have what it takes for serious towing. Every truck shown in this document was
engineered and manufactured with trailering in mind. And with the extensive
lineup of Chevy trucks, you can be sure there is one that is built to meet your
trailering specifications.
SAFE TRAILERING
Safe trailering isn’t just a matter of hitching up and driving off — it places demands
on all the major systems of your truck, including powertrain, steering, suspension
and brake systems. Safe trailering also places the onus on you to meet legal
requirements, follow break in and maintenance schedules, use proper vehicle and
trailer loading guidelines and employ safe driving techniques. See your Owner’s
Manual for more information. Above all, safe and easy trailering requires a properly
equipped vehicle. It is important to ensure that a vehicle is built to handle your
specific trailering requirements. This will help you choose the right truck for the job.
*Silverados, Avalanches, Tahoes and Suburbans can handle loaded trailer weights up to 907 kg (2000 lb.)
where local regulations permit.

WHEN IT COMES TO TRAILER TOWING, ALL VEHICLES ARE
NOT CREATED EQUAL. IT’S IMPORTANT TO SELECT THE RIGHT
VEHICLE WITH THE PROPER EQUIPMENT FOR THE JOB.
Before you can select the right tow vehicle, you need to define your trailering
requirements, including the trailer type, its loaded weight and the way it will be
used. Pick your trailer first.
Even if you plan to tow a trailer for only one or two trips a year, your tow vehicle
must be strong and stable enough to be safe under the most extreme towing situations
it is likely to face. Will towing include trips in mountainous areas with long, steep
grades and high altitudes? Will you be driving it in extreme temperatures? Will
road conditions, winter operation or slippery boat ramps dictate the need for
four-wheel drive? Each of these factors has an impact on your choice of a towing
vehicle. If you plan to use a vehicle primarily for towing, you should optimize its
trailering equipment. If instead you are going to use a vehicle primarily for
personal transportation with only occasional towing, your need for specialized
equipment may be less. But the vehicle still needs to be capable of towing the
trailer you have selected — even the most basic trailering requires some special
equipment. Obviously, trailer weight is critical in vehicle selection. In making this
calculation, don’t forget to include your estimate of the weight of passengers,
cargo and other equipment in the tow vehicle. Once you have established your
trailering requirements, you are ready to determine specifications for the tow
vehicle. Properly selected vehicle components provide the added durability needed
to support, move and stop the extra weight of a trailer.
LOCKING REAR AXLE
A locking-type differential is available in most Chevy trucks and is standard in
many. It permits normal differential action, which helps prevent tire scuffing when
turning. If the differential senses an excessive difference in speed between the
rear driving wheels, it forces power to the wheel with the best traction and is more
effective than the limited slip designs used by most competitors. This advantage is
most evident on slippery surfaces where traction is at a premium, such as on boat
ramps and ice- or snow-covered roads.
TOW/HAUL MODE
Most Chevrolet trucks equipped with a 4-speed automatic transmission feature a Tow/Haul mode,* which helps minimize
wear and tear on the transmission by reducing the frequency of transmission shifting when pulling a heavy trailer. It
also improves performance and control of your vehicle’s speed, for smoother operation. Pressing the Tow/Haul mode
selector switch located on the end of the gearshift lever (on the instrument panel in Express Vans) produces a more
aggressive transmission shift pattern, which lengthens the shift intervals and produces firmer upshifts.
Take note: this is not the overdrive lock-out used by many competitors. In fact, Tow/Haul mode, combined with Passive
Shift Stabilization, permits towing in overdrive for optimum fuel efficiency in most situations. The Passive Shift
Stabilization feature detects and reduces a condition referred to as “shift busyness.”
*Except Colorado, TrailBlazer and Uplander.

POWERTRAIN SELECTION
The greater your towing requirements, the greater the demand you place on your vehicle’s powertrain. That’s why
it is so important to carefully select all your powertrain components in response to your trailering needs. Below
are some key guidelines.
ENGINES
TRANSMISSIONS
The information presented in the charts in this document is intended to help you
identify the right engine for your application. The charts show, by vehicle type
and trailer weight, the minimum engine sizes and available axle ratios needed to
provide good performance at legal highway speeds with no significant reduction
in long-term durability.
Transmissions provide various gear ratios that allow for higher engine rpm
relative to road speed. They also multiply the engine’s torque to provide the
pulling power needed to reach cruising speeds. All Chevy truck transmissions*
feature an overdrive top gear that reduces engine speed when cruising, for
improved fuel efficiency.
Engine performance is measured in horsepower and torque. Horsepower is a
measurement of the work an engine can produce and is a factor of both torque
and engine speed. Torque is a twisting force normally expressed in pounds-feet
(lb.-ft.). You need torque, to put a twisting force on the drive axles and to turn the
wheels when you start a load moving. The engine’s torque can be multiplied using
transmission and drive axle gears. Higher numerical gear ratios increase the
leverage (twisting force) on a rotating shaft. Chevy truck engines are designed
with a broad rpm range in which high torque can be produced and sustained.
Some Chevy trucks offer a choice of manual or automatic transmission. General
Motors recommends automatic transmissions for trailering. Automatic transmissions
utilize a torque converter (a type of fluid coupling) between the engine and
transmission gears. The torque converter is capable of more than doubling the
engine’s torque when starting to move a heavy trailer, in addition to acting as
a cushion to reduce shock loading of powertrain components. The increased
twisting force from the
torque converter is
further multiplied by
the transmission gears
to provide outstanding
load-starting capability —
and there is no
conventional clutch
to slip and burn out.
A larger engine with greater torque and horsepower will provide a performance
improvement while operating with less strain. For example, higher horsepower
allows the engine to maintain highway speeds when pulling a heavy trailer uphill.
Under the following higher performance demands, it is advisable to choose
an engine larger than the minimum recommendation, if one is available:
• if much of the towing will be at high altitudes, since a gasoline engine loses
approximately 10% of its power for every 1000 metres of altitude
Caution: The torque
converter’s operation
causes heat to build
up in the automatic
transmission’s oil,
so all Chevrolet
automatic transmissions
have an oil cooler. For heavy-duty applications such as trailering, your vehicle should
be equipped with additional transmission oil cooling if not standard equipment.
• if mountainous terrain involving long,
steep grades will be
encountered frequently
• if the trailer has a very
large frontal area,
which adds to air drag
and therefore to
pulling requirements
*Except Equinox which uses a 5-speed automatic transmission with a 2.65:1 final drive ratio. Refer to the
Equinox information on page 14 and Owner’s Manual for towing recommendations.
REAR AXLE RATIOS
Another important consideration when determining an ideal trailering vehicle
is the rear axle ratio. Higher axle ratios (4.10:1, for example) increase engine
speed relative to road speed, resulting in increased horsepower development
and torque multiplication. This produces greater towing power, but with a
possible reduction in fuel efficiency when lightly loaded. Overdrive transmissions
help to reduce this negative.
Lower ratios (3.42:1, for example) translate into lower engine rpms, reducing the
torque at the drive wheels. Some gains may be expected in fuel efficiency when
lightly loaded and not towing.

KNOW YOUR WEIGHTS AND HITCHES
Overloading of tow vehicles and trailers compromises safety and can result in vehicle failure. An understanding of
the following terms will assist in proper vehicle selection and help prevent overloading.
DRY TRAILER WEIGHT
HITCHES
The weight of the empty trailer as manufactured. This weight, usually shown on
a vehicle identification plate, is not usually used as a measure for the selection
of a tow vehicle.
Once you have selected your vehicle, the next step is making sure you have
the necessary equipment to help you trailer safely and confidently. The vehicle
owner is responsible for obtaining the hitch ball, a hitch of the proper size,
type and capacity, and other appropriate equipment required to safely tow the
loaded trailer.
LOADED TRAILER WEIGHT
The weight of the trailer (Dry Weight) plus all equipment, fluids and cargo.
Loaded Trailer Weight can be determined by putting the fully loaded vehicle on
a commercial vehicle scale. If this is not practical, the trailer’s Gross Vehicle
Weight Rating (GVWR), as found in the trailer manufacturer’s literature or
brochures for the model selected, can be used when selecting a tow vehicle.
MAXIMUM TRAILER WEIGHT RATING
Often referred to as the Gross Trailer Weight Rating, it is the most weight that a
given vehicle can safely and reliably haul, as determined by the manufacturer.
This rating usually requires optional equipment such as a specific axle ratio,
suspension components, engine and/or transmission coolers and type of hitch.
The rating assumes the tow vehicle is properly equipped with a driver allowance
of 68 kg (150 lb.) and no cargo. The weight of additional options or equipment,
passengers and cargo must be deducted from the trailer weight rating.
GROSS VEHICLE WEIGHT RATING (GVWR)
The maximum allowable weight, as determined by the manufacturer, for any
vehicle (or trailer) including the weight of the vehicle, fuel and other fluids,
driver and passengers, cargo and equipment. Tongue Weight or Kingpin Weight
(see below) is included when trailering.
There are three categories of trailer hitches: weight-carrying, weight-distributing
and fifth-wheel. Each is designed for specific types of trailering.
Weight-Carrying Hitch is the most
basic and most common hitch
for light and medium weights.
A weight-carrying hitch uses a
hitch ball mounted to a draw bar
or a step-bumper and supports the
trailer tongue weight just as though
it were cargo located at the ball.
The hitch ball must match the trailer
coupler and meet or exceed the
maximum trailer weight rating.
Draw bar type weight-carrying hitch.
Weight-Distributing Hitch is used for heavy trailering. This hitch, with its equalizing
bars and snap-up brackets, applies leverage between the tow vehicle and the
trailer to help distribute your trailer’s tongue weight evenly to your vehicle
and trailer instead of “carrying” the load mostly on the rear of the vehicle. The
brackets and spring bars raise the hitch point parallel to the ground, equalizing
the load onto all axles. This results in a more level ride, reduced weight on the
rear suspension and provides improved steering and braking control.
CURB WEIGHT
The weight of the empty vehicle as equipped, including a full tank of fuel. It does
not include the driver, passengers or cargo — so it is similar to Dry Trailer Weight.
PAYLOAD WEIGHT
The weight carried by the vehicle, including the driver, passengers and cargo,
plus options or aftermarket equipment such as boxliners, hitches or fifth wheels.
It should not exceed the Gross Vehicle Weight Rating (GVWR) minus the Curb Weight.
GROSS AXLE WEIGHT RATING (GAWR)
The maximum allowable weight that can be carried on a vehicle’s axle or individual
suspension system, either front or rear. It includes the weight of the vehicle
plus cargo and equipment supported by the axle and includes Tongue Weight
or Kingpin Weight when trailering. These ratings are shown on the vehicle’s
Certification Label, usually located in the driver’s door frame, and should not
be exceeded, nor should the total load exceed the GVWR.
TONGUE WEIGHT/KINGPIN WEIGHT
The weight of the trailer tongue or kingpin that is carried on the hitch ball or
fifth-wheel hitch, respectively. This is a critical measurement as it has an impact
on vehicle handling. Too much Tongue/Kingpin Weight causes overloading of the
rear axle, causing the front suspension to lift and reducing steering response.
Too little Tongue/Kingpin Weight can reduce rear-wheel traction and cause
excessive swaying or jackknifing. Depending on the type of hitch being used,
Tongue Weight is generally 10-15% of the Loaded Trailer Weight. Kingpin Weight
is usualy 15-25% of the trailer weight. Some adjustment to Tongue Weight or
Kingpin Weight can be made by moving the cargo in the trailer.
Weight-distributing hitch.
Fifth-Wheel Hitch, or gooseneck hitch, is used for heavy trailering with a full-size
pickup, and it must be attached to the truck’s frame, usually just slightly ahead
of the rear axle centreline. Make sure to follow the manufacturer’s installation
instructions, paying careful attention to the truck’s payload capacity and rear
axle weight ratings. These kingpin loads are generally higher than conventional
trailer tongue loads and for most calculations becomes the payload in the truck
box. The addition of kingpin weight must not cause the vehicle to exceed its
GVWR or GAWRs.
GROSS COMBINATION WEIGHT RATING (GCWR)
The maximum weight allowable, as established by the manufacturer, for the truck,
the trailer, all equipment, total payload, fuel, fluids and occupants. This is the
total loaded road-ready rig.
Fifth-wheel hitch.

NOTES AND CONDITIONS
TRAILER LOADING
Maximum trailer ratings are calculated based on a properly equipped tow vehicle
with a driver as its only occupant. The weight of additional equipment, passengers
or cargo will reduce the trailer rating. In addition to the weight of the trailer,
maximum trailer weight includes the weight of passengers, equipment and
cargo in the tow vehicle, plus any cargo on the trailer. The addition of the
trailer’s tongue weight (or fifth-wheel kingpin weight) must not cause the vehicle
weights to exceed the Rear Gross Axle Weight Rating (RGAWR) or Gross Vehicle
Weight Rating (GVWR). The tongue load of any trailer is an important weight to
measure because it affects the total or gross vehicle weight of your vehicle as well
as the front and rear axle loads.
If a weight-carrying or a weight-distributing hitch is used, the trailer tongue
weight should be 10-15% of the total loaded trailer weight. The kingpin weight of
fifth-wheel trailers is typically 15-25% of the loaded trailer weight. After you’ve
loaded your trailer, weigh the trailer and then the tongue separately on a commercial
scale to see if the weights are accurate. If they are not, some adjustment can be
made by moving some cargo fore or aft in the trailer. Do not exceed the maximum
allowable tongue weight for your vehicle. The weight of additional equipment,
passengers or cargo in the tow vehicle will reduce the allowable tongue weight.
Refer to the Owner’s Manual for additional information. A Certification/Tire label
can be found on the rear edge of the vehicle’s driver-side door. The label shows
the size of the original tires and the inflation pressures needed to obtain the gross
weight capacity of the vehicle. The GVWR (Gross Vehicle Weight Rating) and both
front and rear GAWRs (Gross Axle Weight Ratings) are also indicated. Never exceed
the GVWR, or the GAWR for either the front or rear axle.
TRAILER BRAKES
The towing vehicle’s brake system is rated for safe operation at the GVWR and
not the GCWR.
If the loaded trailer will weigh more than 450 kg (1000 lb.), it must have its own
separate brakes when towing with a compact or mid-size truck, or an Express Van.
The GM full-size pickups, sport-utilities and chassis cabs can haul trailers weighing
up to 907 kg (2000 lb.) without a separate trailer brake system, where local
regulations permit. Trailer brakes come in three main types:
1. Electric actuation brakes typically utilize the tow vehicle’s battery power and
the brake light circuit to trigger their function. They provide both automatic and
manual control of electric trailer brakes. Recent versions have attempted to use
a sensor in the tow vehicle’s hydraulic system in order to vary trailer brake
pressure in concert with the driver’s input. The GM full-size pickups and sportutility vehicles with the available Z82 Trailering Special Equipment Package
provide an under-dash provision for an Electronic Brake Controller (EBC) jumper
harness. This special wiring harness, with 4 blunt cut wires, is included with the
Trailering Package. It allows the EBC to electronically adjust brake pressure
to the trailer brakes.
TRAILERING AND THE LAW
Trailering laws vary from place to place. A set-up that’s legal in one province may
not be legal in another, or in an American state. In some locations, you may be
required to have a commercial driver’s licence. It pays to check ahead when
planning a trip to ensure your trailering rig meets the local requirements in all
provinces and/or states you will be visiting.
BE SURE AND READ THE TRAILERING INFORMATION FOUND IN YOUR VEHICLE
OWNER’S MANUAL.
2. Hydraulic actuation brakes tap into the tow vehicle’s own brake system and
are not recommended. Although brake modulation is very good, this method is
restricted to large tow vehicles with high volume master cylinders and strongly
assisted power brakes. Care must be taken to follow proper installation procedures
or complete loss of braking may result. The trailer’s brake parts must be able
to withstand 3000 pounds per square inch of pressure and not use more than
0.02 cubic inches of fluid from the tow vehicle’s master cylinder.
3. Surge brakes actuate hydraulic trailer brakes via a master cylinder mounted
in the trailer coupler. As the vehicle slows, the trailer presses (or surges) against
the hitch, operating the master cylinder and applying the brakes. Surge brakes
are ideal for marine trailers where the wheels may be submerged. Surge brakes
present problems when backing up, as they will lock on unless some manually
actuated override is provided.
NOTE: Be sure to read and follow the instructions for the trailer brake controller
so that it is installed, adjusted and maintained properly. Many jurisdictions
require a “breakaway” device which activates the trailer brakes automatically in
the event the trailer becomes detached.

NOTES:
• The maximum allowable Gross Combination Weight Ratings (GCWR) are;
- 8392 kg (18,500 lb.) with the Vortec 6.0L V8 (LY6)
- 9979 kg (22,000 lb.) with the Duramax 6.6L V8 Diesel with Single Rear Wheels (SRW).
- 10,600 kg (23,500 lb.) with the Duramax 6.6L V8 Diesel with Dual Rear Wheels (DRW).
- All 2500HD and 3500HD Series have an automatic transmission and a 3.73 axle ratio as
standard equipment.
- Use this GCWR information when calculating the trailering capacity for Chassis Cabs/Box
Delete (option ZW9) models. The GCWR includes the total loaded weight of the truck, the
body and the trailer.
• The 2500HD and 3500HD models have a weight-carrying hitch limit of 3402 kg (7500 lb.)
and require a weight-distributing hitch with trailer weights in excess of this limit.
• Fifth-wheel kingpin loads are higher than ball hitch trailer tongue loads, so careful attention
must be given to the truck’s payload capacity and rear axle weight ratings (GAWR).
Subtract the tow vehicle’s weight plus passenger and cargo weights from the GVWR to
determine the available payload and/or kingpin weight allowance.
• Trailering kingpin weight should be 15-25% of loaded trailer weight.
• Trailering capacity may be limited by the tow vehicle’s ability to carry the kingpin weight
without exceeding the GVWR or rear GAWR.
• The Integrated Trailer Brake Control (option JL1) is new for 2007 in combination with the
Trailering Special Equipment Package (option Z82). This facilitates hook-up of electric
trailer brakes and provides excellent brake modulation.

NOTES:
• Any Silverado pickup can tow a 907 kg (2000 lb.) trailer without special equipment.
• Weight-Carrying Hitch Limit: 2268 kg (5000 lb.) trailer with 272 kg (600 lb.) tongue weight.
• A Weight-Distributing Hitch and Sway Control is required over 2268 kg (5000 lb.) Trailer Weight.
• Silverado 1500 models are limited to 2268 kg (5000 lb.) trailer rating unless equipped with
Heavy-Duty (Z85), High Performance (Z60), Ride Control (ZX3) or Off-road Suspension
Package (Z71).
• Ball hitch trailers over 2268 kg (5000 lb.) require optional Trailering Special Equipment
(Z82), which includes a weight-distributing hitch platform, extra capacity transmission
cooling, if not already equipped, a high capacity air cleaner, an electric brake control wiring
harness and a heavy-duty 8-lead wiring harness with a 7-pin connector.
• Trailer tongue weight should be 10-15% of the total loaded trailer weight (up to 454 kg (1000 lb.)
on 1500 models – 543 kg (1200 lb.) on models with option NHT, VortecMAX Performance
Package – 680 kg (1500 lb.) on 1500HD models).
• Addition of trailer tongue or kingpin weight must not cause the vehicle weights to exceed the
Rear Gross Axle Weight Rating (RGAWR) or Gross Vehicle Weight Rating (GVWR).
• Trailer 5th-wheel kingpin weight should be 15-25% of the total loaded trailer weight (up to
680 kg (1500 lb.) on 1500 models – 1134 kg (2500 lb.) on 1500HD models). Fifth-wheel
trailers have a greater percentage of their weight on the kingpin (tongue load) than a
conventional trailer. Because of this, greater attention must be given to the maximum
allowable payload and GVWR.
• 1500 Short Box models are neither designed or intended to tow 5th-wheel or
gooseneck trailers.
Caution must be used when selecting a Silverado 1500 model to tow fifth-wheel
trailers due to limited payload and rear axle capacity to handle typical kingpin
weights. Payload capacity is reduced by the added weight of additional optional
equipment plus passengers and cargo in the tow vehicle. Silverado 1500 models
can tow 5th-wheel trailers, within the limits shown on page 9, as long as the
kingpin weight does not cause the vehicle to exceed the GVWR or GAWRs.

Chevrolet recommends that you specify a 4-speed automatic transmission with overdrive for your 1500 Series
Silverado if you plan to tow with it. Trailer ratings for vehicles equipped with a manual transmission are generally
reduced as shown below and on the GCWR chart on page 8. Note that the Vortec 4.3L V6 is the only engine
currently available with a manual transmission.

SILVERADO TRAILER-TOWING FEATURES:
• Automatic transmissions feature a Tow/Haul mode for improved
performance when towing.
• Four-wheel anti-lock braking system (ABS) with
Dynamic Rear Proportioning (DRP) adds a measure of safety
when braking, especially on slippery surfaces.
• Rear axles use a synthetic lubricant for lower operating
temperatures under heavy-load conditions.
• Large, cross-flow radiators with excellent airflow
characteristics keep things cool in extreme conditions.
• The Driver Information Centre (DIC) monitors both engine and
transmission temperatures and alerts the operator of any
problems before damage occurs. A dedicated transmission fluid
temperature gauge is available on 2500HD and 3500 models
that are equipped with an automatic transmission.
• Three-piece modular frame with a hydroformed front section
provides exceptional strength without unnecessary weight.
• Independent front suspension is used on all pickup models,
both two- and four-wheel drive, providing superior ride and
handling. Suspension packages are available for trailering.

SILVERADO 2500HD & 3500 PICKUPS WITH FIFTH-WHEEL HITCH
Often used with the heaviest trailers, fifth-wheel (or gooseneck) hitches are mounted in a pickup’s box and bolted
through the frame with the trailer’s kingpin weight located slightly in front of the tow vehicle’s rear axle. Fifth-wheel
trailer kingpin loads are higher than ball hitch trailer tongue loads, so careful attention must be given to the truck’s
payload capacity and rear-axle weight ratings (GAWR). Subtract the tow vehicle’s weight plus passenger and cargo
weights from the GVWR to determine the available payload and/or kingpin weight allowance.

SRW = Single Rear Wheels DRW = Dual Rear Wheels
Silverado 3500 models
with dual rear wheels
provide an extra
measure of stability,
traction and braking –
important attributes
when towing heavy
fifth-wheel trailers.
Refer to the Gross Combination Weight Ratings shown on page 10 for allowable GCWRs.
NOTES:
• 2500HD and 3500 models have a weight-carrying hitch limit of
3402 kg (7500 lb.) and require a weight-distributing hitch with trailer weights
in excess of this limit.
• Trailer kingpin weight should be 15-25% of total loaded trailer weight.
• Trailering capacity may be limited by the tow vehicle’s ability to carry the
trailer kingpin weight without exceeding the GVWR or Rear GAWR.
Provision for an overdrive lock-out and manual control using a tap-up, tap-down
feature on vehicles equipped with the Allison automatic transmission provides
improved performance and control when towing heavy trailers.

TAHOE, SUBURBAN & AVALANCHE
Ever since Chevrolet introduced the Suburban 69 years ago, it has earned a reputation for outstanding trailering
capabilities. The latest generations of Tahoe, Suburban and Avalanche have taken trailering capacities and functionality
to an even higher level. Among the improvements are more powerful Vortec engines, and stronger frames, as well as
changes to the braking, steering, handling, suspensions and standard StabiliTrak vehicle stability enchancement
system (except Suburban 2500). The result is not just a better full-size SUV, but an even better tow vehicle.

NOTES:
• Maximum limits for a weight-carrying trailer hitch are 1814 kg (4000 lb.)
for the trailer and 227 kg (500 lb.) of tongue weight. A weight-distributing
hitch is not required.
• Trailer tongue weight should be 10-15% of the total loaded trailer weight,
up to a maximum of 227 kg (500 lb.).
• Tongue weight must not cause vehicle weights to exceed Rear Gross Axle
Weight Rating (RGAWR) or Gross Vehicle Weight Rating (GVWR).
• Trailer hitch platform and 4-lead trailer wiring harness are available as
dealer-installed accessories.
GROSS COMBINATION WEIGHT RATINGS (GCWR)
You may prefer to use Gross Combination Weight Ratings (GCWRs) to determine the
engine and rear axle ratio you will require to tow a specific trailer with your Colorado.
The chart below shows you the maximum allowable GCWR based on all the available
GCWR kg (lb.)

NOTES:
• Maximum trailer ratings are calculated assuming standard equipped vehicle,
driver and required trailering equipment. The weight of optional equipment,
passengers and cargo will reduce the maximum trailer weight your vehicle can
tow. 10 to 15% of the trailer weight is the recommended trailer tongue load.
• Trailering capacity may be limited by tow vehicle ability to carry trailer tongue weight.
• A Trailer Towing Package including a 4-pin harness connector and trailer
hitch receiver is available to facilitate trailering with a Equinox.

NOTES:
• Express vans are not equipped or recommended for trailering with a
bumper-mounted ball hitch. If you’ll be towing a trailer, be sure to use
a frame-mounted hitch of the proper size.
• Any Chevy Express can tow a 907 kg (2000 lb.) trailer without special
equipment, except for the appropriate hitch and wiring.
• The weight-carrying hitch limit is a 1814 kg (4000 lb.) trailer with a 181 kg
(400 lb.) tongue weight.
• Express vans towing trailers weighing over 1814 kg (4000 lb.) require a
weight-distributing hitch platform, which is included with optional Z82
Trailering Special Equipment Package.
• The trailering tongue weight should be 10-15% of total loaded trailer weight,
up to 454 kg (1000 lb.).
• The Z82 Trailering Special Equipment Package includes a weight-distributing
hitch platform and a 7-wire trailer wiring harness.
• The base cooling system for vans with a GVWR under 3900 kg (8600 lb.)
includes all that is required to attain the maximum trailer rating. An auxiliary
transmission oil cooler is required on vans with a GVWR of 3900 kg (8600 lb.),
or higher, equipped with a Vortec gasoline engine when the trailer weight exceeds
1814 kg (4000 lb.).
• The standard electrical system was designed to handle one additional
stop/turn light bulb per tail light circuit. The addition of more than one bulb
per circuit may result in damage to the electrical system unless equipped
with the optional 7-wire trailer wiring harness.
