GUIDELINES FOR MATCHING HITCH TRUCK AND TRAILER
If preparing to tow a 5th wheel trailer which you have not rating checked previously, please
consult Appendix A of 5th Wheel Kit assembly instructions.
BEFORE EACH TRIP:
1. Lubricate skid plate surface of the hitch and pivot pin grease fitting (see Figure on cover of Manual) with automotive type
chassis grease or use a plastic lube plate to provide a lubricated surface. Use lithium grease to lubricate pivot points of
moving parts within the hitch.
2. Plastic lube plates (Performance Products No. 83001/40001) can be used to avoid messy grease. The plastic lube plate
must not exceed 3/16 of an inch in thickness to ensure hitch will operate properly. Lube plates must be 12 inches in
diameter or larger to properly distribute king pin weight.
3. Before each trip or maneuver, operate the handle and check that the jaw opens and closes freely.
4. See that all hitch pull pins (#7 (P/N 30434) & #12 (P/N 110974), Figure 11) are in place and the spring retaining clips (#4,
Figure 11) are installed (Figure 1). Note that hitch pull pins used to attach the head assembly to the center section for the 5th
Wheel Kit Hitch are 90 degree bent pins and if replacements are needed, please contact Customer Service at (800) 6323290. Check that all four anchor assembly pins are pinned and have the retaining clips attached.

easily be seen through the
site holes in the top of the
head.
HITCHING PROCEDURE:
IMPORTANT:
YOU ARE RESPONSIBLE FOR SAFE HITCHING AND UNHITCHING OPERATIONS. DO NOT RELY ON
OTHERS TO PERFORM THESE DUTIES. YOU MUST PERSONALLY MAKE SURE THE FOLLOWING
STEPS ARE PERFORMED IN THE FOLLOWING ORDER!
WARNING:
FAILURE TO FOLLOW THESE INSTRUCTIONS MAY RESULT IN DEATH OR SERIOUS INJURY.
1. Place blocks (sometimes called “chocks”) firmly against front and rear of each trailer wheel to prevent any possible
forward or rearward motion. DO NOT REMOVE BLOCKS UNTIL EACH OF THE FOLLOWING STEPS AND THE
PULL TEST HAVE BEEN COMPLETED. Lower tailgate if necessary. Clearance of the lowered tailgate to the trailer needs
to be monitored during hookups as some manufacturer combinations of truck and trailer have little or no clearance.
2. Using trailer jacks, adjust trailer height following the directions in the trailer manual so that bottom of trailer pin box (“A” in
Figure 2) is ½ to 1 inch below skid plate (See “B” in Figure 2). During the hitching maneuver, the bottom of the trailer pin
box should come in contact with skid plate ramp (“C” in Figure 2).

WARNING:
Failure to follow this instruction may result in king pin being too high and coming to rest on top of the closed jaw
or not completely inside jaw. (See Figure 6 & 7). This could result in trailer separating from hitch. Trailer
separation may result in death or serious injury if anyone is under the trailer or between truck and trailer when
separation occurs.
3. Remove bail pin from bail pin hole (see Figure 4). Then pull handle out and rearward to hold open
NOTE: Hitch jaw must be in the open position for king pin to enter the hitch.

6. With all trailer wheels still firmly blocked, landing gear still resting on firm ground and supporting trailer weight, and
truck stationary and in park with emergency brake on: visually check that bottom of pin box is resting on top of the
hitch. THERE SHOULD BE NO SPACE BETWEEN THESE SURFACES (see Figure 6). If space exists, (see
Figure 7) trailer has not been properly hitched. DO NOT TOW! Instead, repeat above steps until trailer is properly
hitched. DO NOT PLACE BODY UNDER TRAILER TO PERFORM THIS INSPECTION!

Connect electrical cable between truck and trailer, connect breakaway switch cable from pin box to a permanent
part of truck, and raise tailgate of truck. Do not tow trailer until the Pull Test has been successfully completed.
WARNING:
Do not attempt to hitch by using trailer jacks to lower trailer and king pin. This could result in king pin
coming to rest on top of skid plate instead of within hitch opening where jaws are located. King pin could
slide off hitch and trailer could drop, resulting in death or serious injury (see Figure 9).

WARNING:
Connection for trailer wiring should be in the side of the truck bed between the driver’s
seat and the wheel well for the back truck axle
Installation of connection rearward of the wheel well may result in user placing body
between truck and trailer. WHENEVER POSSIBLE, AVOID PUTTING BODY UNDER TRAILER
OR BETWEEN TRUCK AND TRAILER!
If you need to place any part of your body under trailer or between truck and trailer:
 All trailer tires MUST be blocked in front and behind each tire AND
 Trailer landing gear MUST be resting on firm ground AND
 Truck MUST be stationary, in park, with emergency brake on!
PULL TEST
WARNING:
Failure to perform pull test may result in death or serious injury
1. With all trailer wheels still firmly blocked, and
2. Trailer landing gear still resting on firm ground and supporting trailer weight and,
3. Truck stationary and with emergency brake on:
4. Make sure no one is between truck and trailer, Return to cab of truck and release truck’s emergency brake. Apply trailer
brakes. Try to pull trailer slowly forward with the truck. If the trailer is properly hitched, the wheel blocks and trailer brakes
should keep the truck from moving forward.
NOTE:
If trailer is not properly hitched, trailer will separate from hitch and truck will move forward leaving trailer behind. If
you followed all previous steps, the trailer will not drop or fall and you will easily be able to repeat the attachment
steps.
WARNING:
Failure to keep wheels blocked and landing gear down could result in trailer suddenly moving or
falling. This could result in death or serious injury!
5. After successfully performing above steps, fully raise trailer landing gear (see trailer manual).
6. Check and inspect all electrical circuits for proper operation. (Clearance lights, turn signals, stop lights, etc.).
7. Remove and store all trailer wheel blocks.
UNHITCHING PROCEDURE:
PERFORM THE FOLLOWING IN THIS ORDER:
1. Make sure truck is in park with emergency brake on.
2. Place blocks firmly against front and rear of each trailer wheel to prevent any possible forward or rearward motion.
3. Using trailer jacks, lower trailer landing gear following the directions in the Trailer Manual until feet of landing gear are
resting on firm ground.
WARNING:
Trailers that are not stable or properly hitched can fall and cause death or serious injury!
To avoid death or serious injury:
• All trailer tires MUST be blocked in front and behind each tire AND
• Trailer landing gear MUST be resting on firm ground AND
• Truck MUST be stationary, in park, with emergency brake on!
4. Lower truck tail gate.
5. Disconnect power cable and breakaway switch cable between truck and trailer.
6. Remove bail pin from hole in handle.
7. Pull hitch handle out completely until it latches in open position so that king pin is no longer
securely grasped by hitch jaws (see Figure 4). Trailer is now free from hitch and truck. If handle does not pull out,
there is probably pressure against the jaw. To relieve this pressure, back the truck slightly or pull the truck slightly
forward. Reset truck emergency brake. Then pull hitch handle out completely until it latches in open position.
8. AFTER MAKING CERTAIN NO ONE IS STANDING BETWEEN TRUCK AND TRAILER OR IN FRONT OF TRUCK,
drive truck slowly away from trailer.
WARNING
Whenever possible, avoid putting body under trailer or between truck and trailer
If you need to place any part of our body under trailer or between truck and trailer:
All trailer tires MUST be blocked in front and behind each tire AND
Trailer landing gear MUST be resting on firm ground AND
Truck MUST be stationary, in park, with emergency brake on!
9. Hitch jaw will automatically close as the king pin is removed from the jaw.
10. KEEP WHEEL BLOCKS IN PLACE. This will keep trailer from moving unexpectedly
MAINTENANCE:
1.
2.
3.
Recheck tightness of all hardware every 1000 miles of use. All 1/2” bolts have a torque specification of
75ft.lbs.
See “Before each trip” section in this manual.
Head assembly to center section should be lubed every 12 months with grease to keep assemblies
moving freely.
WARNING:
Tilting 5th Wheel head can
crush and cut. Keep hands and
fingers clear from this area at
all
times
(including
placement/removal of head).

GUIDELINES FOR MATCHING HITCH, TRUCK, AND TRAILER
WARNING:
Failure to follow all of these instructions may result in death or serious injury!
WARNING:
Failure to check and follow tow ratings could result in tow vehicle
damage or truck and trailer separation while towing.
Trailer and its contents together must not exceed truck, hitch and/or trailer tow
ratings.
Towing vehicle must have a manufacturer’s rated towing capacity equal to or
greater than the gross trailer weight (dry weight of the trailer plus payload of the
trailer). (Figure 12)
Gross weight of trailer must not exceed 20,000 pounds.
King pin weight must not exceed 5,000 pounds (Figure 13). If in doubt have king
pin weight measured by qualified facility.
FACTORY TRAILER + FULL WATER
TANKS + CARGO, ETC.
= GROSS TRAILER WEIGHT
Figure 12
1. Check Tow Ratings:
Vehicle Tow Rating:_______________________.
5th Wheel Kit Hitch Rating:_____20,000 lbs.__.
Gross Trailer Weight (Figure 12):______________.
*Trailer weight should be the lowest of these recorded ratings for safe towing conditions.
2. Cequent Performance Products hitches are designed for use with recreational fifth wheel trailers only. Hitch
applications other than recreational fifth wheel trailers must be approved in writing by Cequent Performance Products’
Engineering Department.
3. Use only a SAE 2-inch kingpin with your 20K Fifth Wheel Hitch.
4. Approximately 15%-25% of trailer weight should be on hitch (Pin Weight). See Figure 13.

5. Trucks come in many different configurations. Cequent Performance Products’ hitches are designed for use in light
trucks such as the Ford F-Series, the Chevy Silverado and the Dodge Ram. Cequent Performance Products
recommends the use of long bed (8ft) light trucks for the best combination in truck - trailer turning clearance.
Rule of thumb:
The distance from the back of the truck cab to the center of the rear truck
axle (“X” in Figure 14), should be approximately 4 inches greater than onehalf the trailer width (“Y” in Figure 4)
RV TRAILER

6. If a short bed pickup (less than 8 ft. but longer than 6 ft.) is to be used for towing, Cequent Performance Products
recommends the trailer be equipped with an extended pin box to help gain additional truck - trailer turning clearance (See
trailer manufacturer for options) (Figure 15). It also may be helpful to add a Square Tube or Round Tube Slider (Part #
30048 / 50008) for increased turning clearance for low speed, non-highway maneuvering.
Figure 15
Conventional Pin Box
Extended Pin Box
WARNING:
Do Not install this fifth wheel hitch on or attempt to tow with a short bed pickup
truck that has a bed shorter than 6 ft.!
7. The height of the hitch and the pin box should be adjusted so the trailer is approximately level as it is towed. Allow
approximately 6 inches clearance between the top of the pickup walls and the underside of the front of the trailer for pitch
and roll of the trailer. (Figure 16). Allow more clearance between pickup walls and trailer for off road use.
Figure 16
Approximately 6 Inches
Level Trailer
CAUTION:
The measurements above are guidelines. If your measurements are close to these numbers re-check
clearances. If vehicle and/or trailer has any added bed vicinity accessories (i.e. fairings, air dams, ground effects,
bed rails, etc.). Additional dimensioning and clearance checks have to be made.
8.
Hitch height determination:
With trailer leveled and on level ground measure from the ground to the king pin box, “A” in Figure 17.
Secondly measure from the height of the inside of the truck bed, “B” in Figure 17. Dimensions “C” and “D” in
Figure 17 can be used to determine the amount of clearance over the side rails, as mentioned in Note 17.
Hitch Height = A – B + 2”
The 2” value is an estimate of suspension compression due to king pin weight of the trailer. This
compression could range between 1”-5” depending on the truck being used and the trailer being towed.
D – C + 2” > 6” as noted in Note 7.

If a lube plate is to be used with a 5th Wheel Kit it must be at least 12” in diameter. Cequent Performance
Products offers this optional lube plate as part # 83001 / 40001.
WARNING:
Connection for trailer wiring must be located at the side of the truck bed between the driver’s
seat and the rear wheel to prevent operators from working between the truck and trailer.
Avoid putting any part of your body under the trailer or between the truck and trailer.
Unexpected or accidental movement of the truck or the trailer can cause serious injury or death
If you must place any part of your body under the trailer or between the truck and trailer you
MUST perform ALL of the following steps:
Check that the truck transmission is in park
Check that the emergency brake is on
Block in front of and behind all trailer tires
Check that the trailer landing gear are resting on firm ground
