The Air Lift LOADLIFTER 5000. 57275 (Part #BBCG57275) fits 2001-2010 Chevrolet Silverado 2500 HD models. The 2010 model year is the last year covered by this part number. For newer models, check for an updated version.
Yes, the Air Lift LOADLIFTER 5000. 57275 (Part #BBCG57275) is designed to fit the 2001-2010 Chevrolet Silverado 2500 HD.
The Air Lift LOADLIFTER 5000. 57275 (Part #BBCG57275) Refer to the included instructions for installation details. Basic hand tools are typically all you need.
The LoadLifter 5000 Series is an air spring suspension support system for 3/4-ton and 1-ton pickup trucks and SUVs with leaf springs. It provides up to 5,000 pounds of load-leveling support with air adjustability from 5–100 PSI. The system uses reinforced, commercial-grade convolute bellows and allows you to adjust air pressure to maintain proper ride height when carrying heavy loads.
Yes, the LoadLifter 5000 Series is designed for 2001–2010 Chevrolet and GMC 2500/3500 models equipped with leaf springs. The installation process differs slightly between 2500 HD and 3500 models due to different strike plate styles and bracket configurations, but both are supported.
No. Installing air springs does not change the GVWR (gross vehicle weight rating), GAWR (gross axle weight rating), or GCWR (gross combined weight rating) of your vehicle. You must still comply with your vehicle's original weight limits. Exceeding the GVWR is dangerous and voids the Air Lift warranty.
There are three versions: (1) Standard LoadLifter 5000 with zinc-plated steel roll plates and black nylon air lines; (2) LoadLifter 5000 Ultimate with black powder-coated roll plates, internal jounce bumper, and black nylon air lines; (3) LoadLifter 5000 Ultimate Plus with stainless steel roll plates, internal jounce bumper, braided stainless steel air lines, and stainless steel air spring mounting hardware. Upgrade kits are available: part 52300 (braided stainless steel air lines and fittings) and part 52301 (complete stainless steel upgrade).
Required tools include: standard and metric open-end or box wrenches, adjustable wrench, ratchet, metric/9/16"/1/2" deep-well sockets, 3/8" and 5/16" drill bits (very sharp), heavy-duty drill, torque wrench, standard and metric hex-key wrenches, hose cutter/razor blade/sharp knife, hoist or floor jacks, two safety stands, safety glasses, air compressor or compressed air source, and a spray bottle with dish soap/water solution.
Yes. Your vehicle may be equipped with a rear brake proportioning valve, which could be affected by load assist products. Air Lift recommends checking 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, installation will have no effect on brake performance.
The elbow fitting (E) should point toward the rear of the vehicle on the driver's side and toward the front of the vehicle on the passenger's side. This orientation is critical for proper air line routing.
Tighten the 90° elbow fitting (E) to the top of the air spring finger tight plus 1½ turns. Be careful to only tighten on the metal hex nut and do not overtighten.
Leave the upper bracket bolts loose during initial assembly. Tighten them only after the assembly is positioned on the axle and aligned so that the air spring is perpendicular to the mounting brackets. The top mounting bolts should be torqued to 20 lb.-ft. (27 Nm).
There should be a thumbs width (approximately 1 inch) of clearance between the air spring roll plate (D) and the leaf spring U-bolt after the upper bracket is tightened.
The top mounting bolts (H) should be torqued to 20 lb.-ft. (27 Nm) after the assembly is properly aligned on the axle.
The axle strap (F) should be attached to the lower bracket carriage bolts and torqued evenly to 16 lb.-ft. (22 Nm).
Yes, you must drill a 5/16" hole in your chosen location for each Schrader valve. Recommended locations are inside the fuel tank filler door, inside rear wheel wells, or the license plate/rear bumper area. For LoadLifter Ultimate Plus kits, the recommended location is the rear bumper area or license plate.
Yes, if you have nylon air lines, you must cut the air line in half using a razor blade or hose cutter, making clean, square cuts. Do not use scissors or wire cutters. The braided stainless steel air lines cannot be trimmed and must be coiled and secured if excess length remains.
Yes, on 2500 HD models only, the driver's side of the axle may have a small bracket with a nut that has nothing attached to it. This bracket must be trimmed off the axle in order to install the assembly.
The minimum bend radius for the nylon air line is 1 inch. Avoid sharp bends and edges, and use zip ties to secure the air line to fixed points along the chassis without pinching or kinking it.
Leave at least 2 inches of slack in the air line to allow for any movement that might pull on the air line.
Use zip ties to secure the braided stainless steel air line to fixed points along the chassis every 6 to 8 inches. Leave at least 2 inches of slack to allow for movement. Do not trim the braided stainless steel air line; coil and secure any excess in an area where it will not be susceptible to damage.
Tighten the air line hex nut finger tight, then use two wrenches to turn one additional flat (1/6 of one full turn). Do not overtighten. The easiest way to tighten the fitting is off the vehicle before installation.
The minimum recommended air pressure is 5 PSI. The maximum air pressure is 100 PSI. Operating the vehicle below the minimum air spring pressure of 5 PSI will void the Air Lift warranty. For unloaded vehicles, the system can safely run at zero air pressure.
Loaded vehicles require at least 25 PSI. A loaded vehicle refers to one with a heavy bed load, a trailer, or both. The springs support approximately 40 pounds of load (combined on both springs) for each 1 PSI of pressure. Never exceed your vehicle's GVWR regardless of air spring pressure or other load assist.
Keep at least 6 inches of clearance between all air lines and the exhaust system. Avoid sharp bends and edges. If a heat shield is included in the kit, install it. If there is no heat shield but one is required, contact Air Lift customer service at (800) 248-0892.
When inflated to 75–90 PSI, there should be at least 1/2 inch clearance from anything that might rub against the air spring sleeve. Check the tire, brakes, frame, shock absorbers, and brake cables.
Inflate the air springs to 30 PSI and spray all connections and inflation valves with a solution of 1/5 liquid dish soap and 4/5 water. Spot leaks by looking for bubbles in the soapy water. After the test, deflate the springs to the minimum pressure required to restore normal ride height (at least 5 PSI). Check air pressure again after 24 hours; a 2–4 PSI loss is normal. If loss exceeds 5 PSI, retest for leaks.
After completing clearance, leak, heat, and fastener tests, road test the vehicle at recommended driving pressures. Drive 10 miles and recheck for clearance, loose fasteners, and air leaks. After 24 hours of use, recheck air pressure; if it has dropped more than 5 PSI, there is a leak that must be fixed.
Recheck the air spring system after 30 days or 500 miles, whichever comes first. Check all fasteners for tightness. If any part shows signs of rubbing or abrasion, identify and move the source if possible. If relocation is not possible, the air spring may need to be remounted.
Check air pressure weekly to maintain optimal performance and ride height.
If the air springs are properly installed and maintained, they can last indefinitely.
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, support the axle with jack stands to take the tension off the air springs. If you need to raise the vehicle by the frame, deflate the system to minimum pressure (5 PSI) to reduce tension on suspension and brake components.
Periodically give the air springs a hard spray with a garden hose to remove mud, sand, gravel, or other debris.
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, though it requires more effort.
Tuning comes down to three things: level vehicle, ride comfort, and stability. (1) Level vehicle: if headlights shine into trees or vehicle leans to one side, raise air pressure. (2) Ride comfort: if ride is rough or harsh, try different pressures to find the best comfort. (3) Stability: prioritize stability over a perfectly level ride; increase pressure to reduce roll, bounce, dive during braking, and sponginess. Start with the vehicle level or slightly above, and when in doubt, add air. It may be necessary to maintain different pressures on each side; differences up to 50 PSI are not uncommon.
If the front of the vehicle dives while braking, increase the pressure in the front air bags if equipped.
If the vehicle rocks and rolls, adjust the air pressure to reduce movement. Stability issues usually require an increase in pressure.
Yes, the LoadLifter 5000 Series is designed for 2001–2010 Chevrolet and GMC 2500/3500 models with leaf springs. Installation differs slightly between 2500 HD and 3500 models.
You need wrenches, sockets, a heavy-duty drill with 3/8" and 5/16" bits, torque wrench, hose cutter, hoist or floor jacks, two safety stands, safety glasses, air compressor, and a spray bottle with soap solution.
Yes, you must drill 5/16" holes for the Schrader valves. On 2500 HD models, a small bracket on the driver's side axle must be trimmed off. Nylon air lines must be cut in half with a razor blade or hose cutter.
Upper bracket bolts: 20 lb.-ft. (27 Nm). Axle strap bolts: 16 lb.-ft. (22 Nm). Elbow fitting: finger tight plus 1½ turns. Braided stainless steel air line hex nut: finger tight plus one additional flat (1/6 turn).
Minimum: 5 PSI (required to maintain warranty). Maximum: 100 PSI. Loaded vehicles require at least 25 PSI. Keep air lines 6 inches away from the exhaust system.
Perform clearance test (1/2" minimum at 75–90 PSI), leak test (check all connections with soapy water), heat test (6" clearance from exhaust), fastener test (recheck all bolt torque), and a 10-mile road test. Recheck pressure after 24 hours; loss over 5 PSI indicates a leak.
Check air pressure weekly. Recheck fasteners periodically. Perform a 30-day or 500-mile inspection. If the vehicle is on a hoist for extended service, support the axle with jack stands. Spray air springs with a garden hose to remove debris.
Check for leaks using a soapy water solution (1/5 liquid dish soap and 4/5 water). Leak test the air line connections, the threaded connection into the air spring, and all fittings in the control system. Ensure air lines are seated in connectors. If the air line is kinked or folded, replace it. Trim the hose or re-seal the fitting, ensuring lines are cut straight. If the problem persists, contact Air Lift customer service at (800) 248-0892.
Look for a kink or fold in the air line. Replace any air line that has been kinked. Also check for improperly installed air lines, holes or cracks in the line, or compromised fitting seals. Inspect fittings with soapy water and trim or re-seal as needed.
First, 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 inch off the end of the air line with a clean, square cut. Reinsert the air line into the push-to-connect fitting. If it still leaks, tighten the swivel fitting another half turn. If it still leaks, deflate the air spring, remove the fitting, re-coat the threads with thread sealant, and reinstall by hand tightening as much as possible, then use a wrench for an additional two turns.
First, check the valve core by tightening it with a valve core tool. If that does not work, check the air line by removing it from the barbed type fitting. Cut the air line off a few inches in front of the fitting and use pliers or vice grips to pull or twist the air line off the fitting. Do not cut off the air line completely as this will nick the barb and render the fitting useless. If the problem persists, contact Air Lift customer service at (800) 248-0892.
