LoadLifter 5000

Introduction

The purpose of this publication is to assist with the installation, maintenance and troubleshooting of the LoadLifter 5000 air spring kit. LoadLifter 5000 utilizes sturdy, reinforced, commercial grade single or double, depending on the kit, convolute bellows. The bellows are manufactured like a tire with layers of rubber and cords that control growth. LoadLifter

5000 kits are recommended for most 3/4 and 1 ton pickups and SUVs with leaf springs and provide up to 5,000 lbs. of oad leveling support with air adjustability from 5-100 PSI. The kits are also used in motor home rear kits and some motor home fronts where leaf spring are used.

It is important to read and understand the entire installation guide before beginning installation or performing any maintenance, service or repair. The information here includes a hardware list, tool list, step-by-step installation information, maintenance guidelines and operating tips.

Air Lift Company reserves the right to make changes and improvements to its products and publications at any time. For the latest version of this manual, contact Air Lift Company at

(800) 248-0892 or visit our website at www.airliftcompany.com.

IMPORTANT SAFETY NOTICE

The installation of this kit does not alter the Gross Vehicle Weight Rating (GVWR) or payload of the vehicle. Check your vehicle’s owner’s manual and do not exceed the maximum load listed for your vehicle.

Gross Vehicle Weight Rating: The maximum allowable weight of the fully loaded vehicle

(including passengers and cargo). This number — along with other weight limits, as well as tire, rim size and inflation pressure data — is shown on the vehicle’s Safety Compliance

Certification Label.

Payload: The combined, maximum allowable weight of cargo and passengers that the truck is designed to carry. Payload is GVWR minus the Base Curb Weight.

Installing the LoadLifter 5000 System

GETTING STARTED

1. Raise the vehicle and support it in a way, using jack stands or equivalent, that the axle can be safely dropped away from the frame. This will need to be done in order for the air spring assembly to be put into position between the axle and frame (figs. 1a, 1b and

2). Figure 2 shows the frame being supported with the vehicle on a drive on hoist.

fig. 2

2. Remove the jounce bumpers from under the frame, over the axle (figs. 3 and 4).

TECH TIP: Wire brush the stud on the jounce bumper and use some penetrating oil to help in removal of the jounce bumper. Usually the socket size for the nut is a 15mm.

fig. 3 fig. 4

MN-770

LoadLifter 5000

3. If necessary, disconnect the wiring harness from the driver side frame rail to gain clearance for the upper brace (fig. 5). Also, push the harness connector out that holds the electrical lines going to the gas/urea tank in or out of the tank bracket. This will improve the socket/ bolt access that will be required for installing and tightening the frame brace (fig. 6).

Remove the line holders from the gas/urea tank bracket for easier access to the upper brace hardware.

fig. 5

4. If you have a fifth wheel hitch already installed,

other than the standard factory Reese

hitch purchased with the truck, it will be necessary to remove the hardware that bolts the side bracket (plates) to the outside of the frame above the axle.

Set left side brace inside the frame (D)

Frame Rail

Push this electrical harness connector out of the gas/ urea tank bracket for better access to mounting hole/ slot in frame.

fig. 6

MN-770

INSTALLING THE BRACES

Gas engine models have emission lines on the inside of the frame. If your truck has emission lines running along the inside of the frame rail (fig. 7), it will be necessary to relocate those lines as follows:

1. Carefully push the line holder out of the frame above the axle. Try to minimize damage because it will be reused later. It may also be helpful to remove any emissions/fuel line retaining clips forward or rearward of the axle to aid in positioning the lines once the upper brace has been installed (figs. 7 and 8). The same holds true with the electrical wire loom retaining clips.

If equipped, this emissions/fuel line retaining clip must be pulled away from the frame in order to install the upper frame brace (D).

fig. 8

RETAINING CLIP L-BRACKET INSTALLATION ON BRACE

1. In order to re-attach the previously removed emissions line, it will be necessary to attach the provided L-bracket (L) to the back frame brace using the 1/4”-20 x 1” bolt (M), flat washers #12 (Q) and 1/4”-20 Nyloc nut (T) supplied (fig. 6). Placing this L-bracket depends on where the line holder is on the wiring or the emissions line that was previously pulled from the frame. Set the driver side frame brace (D) up into the frame and insert the 8mm-1.25 x 25mm hex cap screw (BB) with an M8 flat washer (X) through the brace and into the hole in the side of the frame that the line holder was removed from (fig. 9) to hold it in place and note what side the line holder is in, in respect to the back leg of the brace. Is it forward or behind the back leg of the brace? Where the line holder lines up is the side where the L-bracket is to be installed (figs. 6 and 9).

Brace being temporarily held in place by the

8mm bolt and washer.

L-bracket is shown in location already. Note: the side the line holder is on depends on the location of the factory retaining clip.

fig. 9

2. Pull the brace back out and attach the L-bracket onto the brace with the hardware noted above, in the proper location previously found (figs. 10 and 11). Make sure the L-bracket faces up and tighten securely.

fig. 10

Attach the L-bracket to the brace in the position previously found using the hardware specified.

fig. 11

No matter what side the L-bracket is on, make sure it is installed so the flat side points up when tightening.

CAUTION

DRIVER SIDE BRACE INSTALLATION

1. Set the left upper brace (D) into the driver side frame rail. The brace has a small hole that will line up with an existing hole in the frame, insert the 8mm-1.25 x 25mm hex cap screw (BB) with an M8 flat washer (X) through the brace and frame (figs. 12 and 13) and cap with M8 flat washer (X) and M8 x 1.25 Nyloc nut (HH). Leave loose at this time.

OR

If you have an aftermarket fifth wheel hitch that has an outer bracket (plate) running along side of the frame and it used this slot to secure the bracket with existing hardware, install the original fifth wheel hardware previously removed in the “getting started section” from the fifth wheel installation for securing the brace (fig. 12). Do not tighten at this time.

OR

If you have an aftermarket fifth wheel hitch that has an outer bracket (plate) running along side of the frame and it does not have any attaching hardware on the side where the slot in the frame is, it will be necessary to drill a 1/2” hole through the plate using the slot in the frame as a template. Drill the hole as far to the rear of the slot as you can.

CLEAR ANY ELECTRICAL OR HARD LINES FROM THE AREA SO AS NOT TO DAMAGE

THEM IN ANY WAY WHEN DRILLING THE HOLE.

It may be necessary to mark and remove the outer bracket (plate) from the side of the frame in order to drill the hole correctly. Re-attach once the hole is drilled.

Insert a 1/2”-13 x 3.00” hex cap screw (N) with a 1/2” flat washer (W) through the brace, frame and fifth wheel plate previously drilled. Cap with a 1/2” flat washer (W) and a

1/2”-13 serrated flange lock nut (FF) (fig. 12). Leave loose at this time.

ATTACHING THE ASSEMBLIES TO THE FRAME

1. If not done so yet, drop the axle or raise the frame up to make room for the assemblies to be put into position.

2. Set the left (driver side) assembly onto the jounce bumper strike plate (figs. 34 and 35).

Make sure the 3/8”-16 x 10” carriage bolt (EE) on the bottom bracket goes in between the hard brake line and the axle (this should be on the back side of the axle). Raise the axle just enough to insert the 3/8”-16 x 2” carriage bolt (GG) (that is installed in the upper bracket) through the existing jounce bumper hole in the bottom of the frame. At the same time, line up the upper brace previously installed onto the remaining two carriage bolts in the upper bracket (figs. 36 and 37). Do this just enough for the carriage bolt to hold the assembly into position on the jounce bumper strike plate (figs. 1a and 12).

Torque the axle clamp bar bolts to 16ftlbs (figs. 50 and 51). Repeat for the opposite side. Trim the 3/8”-16 x 10” carriage bolts below the Nyloc nuts if necessary.

DO NOT PINCH THE HARD BRAKE LINE ON THE PASSENGER SIDE WHILE

TIGHTENING. It may be necessary on some models to not tighten the axle clamp bar

evenly on the right side (passenger side) so that the clamp bar will clear the hard brake line.

Once tight, the upper and lower bracket will not be parallel and may look like they are out of

alignment. This condition will be OK because of the way the lower bracket and upper bracket

mounts, also there may be some variance in models and this is considered a normal condition.

NOTE

INSTALLING THE AIR LINES

1. Choose a convenient location for mounting the inflation valves. Popular locations for the inflation valve are: a. The wheel well flanges b. The license plate recess in bumper c. Under the gas cap access door d. Through the license plate

Whatever the chosen location, make sure there is enough clearance around the inflation

valves for an air chuck.

2. Drill two 5/16” holes to install the inflation valves.

3. Cut the air line assembly in two equal lengths.

Good Cut Poor Cut

WHEN CUTTING OR TRIMMING THE AIR LINE, USE A HOSE CUTTER, A RAZOR BLADE,

OR A SHARP KNIFE. A CLEAN, SQUARE CUT WILL ENSURE AGAINST LEAKS. DO

NOT USE WIRE CUTTERS OR SCISSORS TO CUT THE AIR LINE. THESE TOOLS MAY

FLATTEN OR CRIMP THE AIR LINE CAUSING IT TO LEAK AROUND THE O-RING SEAL

4. Place a 5/16” nut and star washer on the air valve. Leave enough of the inflation valve in front of the nut to extend through the hole and have room for the rubber washer, flat washer, and 5/16” nut and cap. There should be enough valve exposed after installation— approximately 1/2 — to easily apply a pressure gauge or an air chuck (fig. 53).

5. Push the inflation valve through the hole and use the rubber washer, flat washer, and another 5/16” nut to secure it in place. Tighten the nuts to secure the assembly.

6. Route the air line along the frame to the air fitting on the air spring (fig. 54). Keep AT

LEAST 6” of clearance between the air line and heat sources, such as the exhaust pipes, muffler, or catalytic converter. Avoid sharp bends and edges. Use the plastic tie straps to secure the air line to fixed, non-moving points along the chassis. Be sure that the tie straps are tight, but do not pinch the air line. Leave at least 2” of slack to allow for any movement that might pull on the air line.

8. Cut off the air line, leaving approximately 12” of extra air line. A clean square cut will prevent leaks. Insert the air line into the air fitting. This is a push-to-connect fitting. Simply push the air line into the 90° swivel fitting until it bottoms out (9/16” of air line should be in the fitting).

INSTALLING THE HEAT SHIELD

1. Bend tabs to provide a dead air space between exhaust pipe and heat shield (fig. 56).

2. Attach the heat shield to the exhaust pipe using the clamps. Bend the heat shield for maximum clearance to the air spring (fig. 56).

3. Finished heat shield installation (fig. 56).

CHECKING FOR LEAKS

1. Inflate the air spring to 30 PSI.

2. Spray all connections and the inflation valves with a solution of 1/5 liquid dish soap and

4/5 water. Spot leaks easily by looking for bubbles in the soapy water.

3. After the test, deflate the springs to the minimum pressure required to restore the system to normal ride height. Do not deflate to lower than 5 PSI.

4. Check the air pressure again after 24 hours. A 2 - 4 PSI loss after initial installation is normal. Retest for leaks if the loss is more than 5 lbs.

FIXING LEAKS

1. If there is a problem with the swivel fitting: a. Check the air line connection by deflating the spring and removing the line by pulling the collar against the fitting and pulling firmly on the air line. Trim 1” off the end of the air line. Be sure the cut is clean and square (see fig. 52). Reinsert the air line into the push-to-connect fitting.

b. Check the threaded connection by tightening the swivel fitting another 1/2 turn. If it still leaks, deflate the air spring, remove the fitting, and re-coat the threads with thread sealant. Reinstall by hand tightening as much as possible and then use a wrench for an additional two turns.

2. If there is a problem with the inflation valve: a. Check the valve core by tightening it with a valve core tool.

b. Check the air line by removing the air line from the barbed type fitting. Cut the air line off a few inches in front of the fitting and use a pair of pliers or vice grips to pull/ twist the air line off of the fitting.

DO NOT CUT OFF THE AIR LINE COMPLETELY AS THIS WILL USUALLY NICK THE

BARB AND RENDER THE FITTING USELESS.

MAINTENANCE GUIDELINES

By following the steps below, vehicle owners will obtain the longest life and best results

from their air springs.

1. Check the air pressure weekly.

2. Always maintain normal ride height. Never inflate beyond 100 PSI.

3. If you develop an air leak in the system, use a soapy water solution (1/5 liquid dish soap and 4/5 water) to check all air line connections and the inflation valve core before deflating and removing the air spring.

FOR YOUR SAFETY AND TO PREVENT POSSIBLE DAMAGE TO YOUR VEHICLE, DO

NOT EXCEED MAXIMUM GROSS VEHICLE WEIGHT RATING (GVWR), AS INDICATED

BY THE VEHICLE MANUFACTURER. ALTHOUGH YOUR AIR SPRINGS ARE RATED

AT A MAXIMUM INFLATION PRESSURE OF 100 PSI, THE AIR PRESSURE ACTUALLY

NEEDED IS DEPENDANT ON YOUR LOAD AND GVWR.

4. Loaded vehicles require at least 25 PSI or more. A “loaded vehicle” refers to a vehicle with a heavy bed load, a trailer, or both. As discussed above, never exceed GVWR, regardless of air spring, air pressure, or other load assist. The springs in this kit will support approximately 40 lbs. of load (combined on both springs) for each 1 PSI of pressure.

The required air pressure will vary depending on the state of the original suspension.

Operating the vehicle below the minimum air spring pressure will void the Air Lift warranty.

5. When increasing load, always adjust the air pressure to maintain the normal ride height.

Increase or decrease pressure from the system as necessary to attain normal ride height for optimal ride and handling. Remember that loads carried behind the axle (including tongue loads) require more leveling force (pressure) than those carried directly over the axle.

6. Always add air to springs in small quantities, checking the pressure frequently.

7. Should it become necessary to raise the vehicle by the frame, make sure the system is at minimum pressure (5 PSI) to reduce the tension on the suspension/brake components.

Use of on board leveling systems do not require deflation or disconnection.

8. Periodically check the air spring system fasteners for tightness. Also, check the air springs for any signs of rubbing. Realign if necessary.

9. On occasion, give the air springs a hard spray with a garden hose in order to remove mud, sand, gravel or other abrasive debris.

TROUBLESHOOTING GUIDE

1. Leak test the air line connections, the threaded connection into the air spring, and all fittings in the control system.

2. Inspect the air lines to be sure none are pinched. Tie straps may be too tight. Loosen or replace the strap and replace leaking components.

3. Inspect the air line for holes and cracks. Replace as needed.

4. Look for a kink or fold in the air line. Reroute as needed.

If the preceding steps do not solve the problem, it is possibly caused by a failed air spring — either a factory defect or an operating problem. Please call Air Lift at (800) 248-0892 for assistance.

FREQUENTLY ASKED QUESTIONS

Q . Will installing air springs increase the weight ratings of a vehicle?

No. Adding air springs will not change the weight ratings (GAWR, GCWR and/or GVWR) of a vehicle. Exceeding the GVWR is dangerous and voids the Air Lift warranty.

Q . Is it necessary to keep air in the air springs at all times and how much pressure will they need?

For LoadLifter 5000 Ultimate, the recommended minimum air pressure is 5 PSI, but it can safely be run at zero air pressure.

Q . Is it necessary to add a compressor system to the air springs?

No. Air pressure can be adjusted with any type of compressor as long as it can produce sufficient pressure to service the springs. Even a bicycle tire pump can be used, but it’s a lot of work.

Q . How long should air springs last?

If the air springs are properly installed and maintained they can last indefinitely.

Q . Will raising the vehicle on a hoist for service work damage the air springs?

No. The vehicle can be lifted on a hoist for short-term service work such as tire rotation or oil changes. However, if the vehicle will be on the hoist for a prolonged period of time, support the axle with jack stands in order to take the tension off of the air springs.

TUNING THE AIR PRESSURE

Pressure determination comes down to three things — level vehicle, ride comfort, and stability.

1 . Level vehicle

If the vehicle’s headlights are shining into the trees or the vehicle is leaning to one side, then it is not level (fig. 2.1). Raise the air pressure to correct either of these problems and level the vehicle.

2 . Ride comfort

If the vehicle has a rough or harsh ride it may be due to either too much pressure or not enough (fig. 2.2). Try different pressures to determine the best ride comfort.

3 . Stability

Stability translates into safety and should be the priority, meaning the driver may need to sacrifice a perfectly level and comfortable ride. Stability issues include roll control, bounce, dive during braking and sponginess (fig. 2.3). Tuning out these problems usually requires an increase in pressure.

GUIDELINES FOR ADDING AIR

1. Start with the vehicle level or slightly above.

2. When in doubt, always add air.

3. If the front of the vehicle dives while braking, increase the pressure in the front air bags, if equipped.

4. If it is ever suspected that the air bags have bottomed out, increase the pressure (fig. 2.4).

5. Adjust the pressure up and down to find the best ride.

6. If the vehicle rocks and rolls, adjust the air pressure to reduce movement.

7. It may be necessary to maintain different pressures on each side of the vehicle. Loads such as water, fuel, and appliances will cause the vehicle to be heavier on one side (fig.

2.5). As much as a 50 PSI difference is not uncommon.

Choosing the Right On-Board Air Compressor System

Add an on-board air compressor sytem to inflate and deflate your air springs with the touch of a button — from inside or outside of the vehicle .

• For convenient, on-the-go control of your air springs, add an Air Lift on-board air compressor system.

• Air Lift on-board air compressor systems eliminate the search for gas stations that have a working compressor, saving you time, energy and money.

• All systems include a compressor, controller and all parts needed for easy installation.

1. Choose single or dual path inflation (see illustrations at right)

2 . Choose wireless or analog control

• Wireless: Control your air springs from inside or outside the vehicle. Easiest installation - no wires to the cab.

• Analog: In-cab control of your air springs.

Economically priced.

Dual path systems Air springs are controlled separately to allow for different air pressure from side-to-side. Perfect for uneven or top-heavy loads.

3 . Choose heavy or standard duty compressor

• Standard duty: A standard duty compressor will work well for most customers who use their system on an intermittent basis.

• Heavy duty: For daily use, consider the heavy duty compressor - it inflates faster and more quietly than the standard compressor.
