The LoadLifter 5000 is an air spring suspension support system that uses reinforced, commercial-grade convolute bellows to provide load assistance. It helps support additional cargo weight on the rear suspension. The system does not alter the vehicle's Gross Vehicle Weight Rating (GVWR) or payload capacity; you must still comply with your vehicle manufacturer's maximum load limits.
Your vehicle may be equipped with a rear brake proportioning valve, which could be affected by load assist products. Check with your dealer before installation. If your vehicle does not have a rear brake proportioning valve or is equipped with an anti-lock brake system, the LoadLifter 5000 will have no effect on brake performance.

1. Set a roll plate on both ends of the air spring with the radiused (rounded) edge facing the air spring. 2. Install the 90-degree elbow fitting to the top of the air spring and tighten finger-tight plus 1.5 turns, tightening only on the metal hex nut—do not over-tighten. 3. Set the upper bracket over the top of the air spring and attach using two 3/8" bolts, two lock washers, and two flat washers, tightened securely. 4. Set the lower bracket on the bottom of the air spring, offset to the outside of the vehicle. 5. Attach using two 3/8" bolts, two lock washers, and two flat washers, but leave loose for later adjustment.
1. Remove the bolts holding the jounce bumper bracket. 2. Remove the jounce bumper bracket from the side of the frame. Use extreme caution to avoid damaging the lines on the inside of the frame on the passenger's (right) side. 3. Drill the two bottom holes with a 1/2" drill bit. If unable to drill from the outside in, drill from the inside of the frame out.
Two 1/2" holes must be drilled in the jounce bumper bracket area. Additionally, a 5/16" hole must be drilled to install each inflation valve. A 3/8" hole must be drilled above the axle in the bottom of the frame flange to relocate the jounce bumper.
1. Set the assembly on the leaf spring and insert two 1/2" carriage bolts through the bottom holes in the upper bracket and frame. Install a flat washer and nylon lock nut to each bolt, leaving loose for adjustment. 2. Insert two 3/8" frame bolts through the top holes in the upper bracket and frame. Secure using flat washers and nylon lock nuts on the inside of the frame. 3. Align the air spring so it is parallel and perpendicular to the top and bottom using the slotted lower bracket. 4. Tighten the lower air spring/bracket mounting hardware to 10 lb.-ft. (13.6 Nm). 5. Tighten all upper bracket mounting hardware. 6. Attach the lower bracket to the leaf spring with the long U-bolts, capping with flat washer and nylon lock nut. Trim U-bolts above the nylon lock nut if necessary. 7. Tighten all mounting hardware to the specified torque values.
The lower air spring/bracket mounting hardware must be tightened to 10 lb.-ft. (13.6 Nm). The manual does not specify torque values for other fasteners; contact Air Lift Company at (800) 248-0892 for complete torque specifications.
Popular locations for the inflation valves include: the wheel well flanges, license plate recess in bumper, under the gas cap access door, or through the license plate itself. Choose a location with enough clearance around the inflation valves for an air chuck to be applied.
Cut the air line assembly into two equal lengths using a hose cutter, razor blade, or sharp knife. Make a clean, square cut to prevent leaks. Do not use wire cutters or scissors, as these tools may flatten or crimp the air line, causing it to leak around the O-ring seal inside the elbow fitting.
1. Drill a 5/16" hole at your chosen location. 2. Place a 5/16" nut and star washer on the air valve, leaving approximately 1/2" of valve exposed after installation to easily apply a pressure gauge or air chuck. 3. Push the inflation valve through the hole. 4. Install the rubber washer, flat washer, and another 5/16" nut on the back side. 5. Tighten the nuts to secure the assembly in place. 6. Install the valve cap.
Route the air line along the frame to the air fitting on the air spring. Maintain at least 6" (150 mm) of clearance between the air line and heat sources such as exhaust pipes, muffler, or catalytic converter. Avoid sharp bends and edges. Use plastic zip ties to secure the air line to fixed, non-moving points along the chassis. Ensure zip ties are tight but do not pinch the air line. Leave at least 2" (50 mm) of slack to allow for movement that might pull on the air line.
Cut the air line leaving approximately 12" (300 mm) of extra air line, making a clean square cut to prevent leaks. The 90-degree swivel fitting on the air spring is a push-to-connect fitting. Simply push the air line into the fitting until it bottoms out; approximately 9/16" of air line should be inserted into the fitting.
1. Remove the jounce bumper from the stock bracket. 2. Drill a 3/8" hole above the axle in the bottom of the frame flange. 3. Mount the jounce bumper under the frame using O.E.M. hardware and tighten securely. The jounce bumper must be positioned between the frame and axle. Drop the axle slightly if necessary to achieve proper positioning.
Minimum recommended air pressure is 5 PSI (0.34 BAR). Maximum air pressure is 100 PSI (7 BAR). Never inflate beyond 100 PSI. The actual air pressure needed depends on load and gross vehicle weight rating.
The maximum air pressure is 100 PSI (7 BAR). Do not exceed this pressure. Although the air springs are rated at 100 PSI maximum, the actual pressure needed depends on your load and your vehicle's gross vehicle weight rating. Never exceed your vehicle's GVWR or payload rating as indicated by the vehicle manufacturer.
Perform the following checks: (1) Clearance test—inflate to 40-60 PSI and verify at least 1/2" clearance from tire, brakes, frame, shock absorbers and brake cables. (2) Leak test—inflate to 40-60 PSI and check all connections for leaks before road testing. (3) Heat test—verify at least 6" clearance from heat sources (exhaust, muffler, catalytic converter). (4) Fastener test—after 500 miles, recheck all bolts for proper torque. (5) Road test—drive 10 miles and recheck for clearance, loose fasteners and leaks.
Check air pressure weekly. Always maintain normal ride height. Never inflate beyond 100 PSI (7 BAR). If the system develops an air leak, use a soapy water solution to check all air line connections and the inflation valve core before deflating and removing the air spring. After 500 miles, recheck all bolts for proper torque.
No. The installation of the LoadLifter 5000 does not alter the Gross Vehicle Weight Rating (GVWR) or payload of the vehicle. You must check your vehicle's owner's manual and not exceed the maximum load listed for your vehicle. GVWR is the maximum allowable weight of the fully loaded vehicle including passengers and cargo. Payload is the combined maximum allowable weight of cargo and passengers, calculated as GVWR minus the base curb weight.
Do not try to inflate the air springs until they have been properly secured to the vehicle. Compressed air can cause injury and damage to the vehicle and parts if not handled properly. Always follow the maintenance guidelines: check air pressure weekly, maintain normal ride height, and never inflate beyond 100 PSI (7 BAR).
Use a spray bottle with a soapy water solution to check all air line connections and the inflation valve core. Spray the solution on all connections and look for bubbles, which indicate a leak. All leaks must be eliminated before the vehicle is road tested. If a leak is found, deflate and remove the air spring to repair the connection.
Yes, kit 57292 is designed specifically for 2004-2006 Chevrolet 5500 Cutaway vehicles.
You need a hoist or floor jacks, safety stands, torque wrench, 1/2" and 5/16" wrenches, adjustable wrench, ratchet with sockets, two very sharp 5/16" drill bits, heavy duty drill, hose cutter or sharp knife, air compressor, and spray bottle with soapy water solution.
Yes. You must drill two 1/2" holes in the jounce bumper area, a 5/16" hole for each inflation valve, and a 3/8" hole above the axle in the frame flange to relocate the jounce bumper.
Tighten the lower air spring/bracket mounting hardware to 10 lb.-ft. (13.6 Nm). Contact Air Lift Company at (800) 248-0892 for torque specifications for other fasteners.
Never exceed 100 PSI (7 BAR). The actual pressure needed depends on your load and vehicle GVWR. Do not exceed your vehicle's maximum GVWR or payload rating.
Perform clearance test at 40-60 PSI (verify 1/2" clearance from tire, brakes, frame, shocks, cables), leak test (check all connections), heat test (6" clearance from exhaust), and after 500 miles recheck all bolts for torque. Road test after these checks.
Check air pressure weekly. Maintain normal ride height and never inflate beyond 100 PSI. After 500 miles, recheck all bolts for proper torque.
Check with your dealer before installation if your vehicle has a rear brake proportioning valve. If your vehicle lacks this valve or has anti-lock brakes, the LoadLifter 5000 will not affect brake performance.
This is typically caused by an improper cut on the air line. Do not use wire cutters or scissors to cut the air line, as these tools flatten or crimp the line. Always use a hose cutter, razor blade, or sharp knife to make a clean, square cut. If a leak is detected, deflate the system, remove the air line, and cut a new square end before reinserting into the fitting.
Use a spray bottle with soapy water solution to check all air line connections and the inflation valve core. Spray the solution on connections and look for bubbles indicating a leak. Once identified, deflate and remove the air spring to repair the connection. Common leak sources are improper air line cuts (use hose cutter, not wire cutters) or loose fittings. Ensure all connections are properly seated and tightened.
