The Air Lift LoadLifter 5000 ULTIMATE with internal jounce bumper 88242 (Part #BBCG88242) fits 2003-2026 Ford E-450 Super Duty models. The 2026 model year is the last year covered by this part number. For newer models, check for an updated version.
The Air Lift LoadLifter 5000 ULTIMATE with internal jounce bumper 88242 (Part #BBCG88242) Refer to the included instructions for installation details. Basic hand tools are typically all you need.
The LoadLifter 5000 Ultimate is an adjustable air helper spring system that provides load-leveling support for 3/4-ton and 1-ton pickups and SUVs with leaf springs. It uses reinforced, commercial-grade convolute bellows and provides up to 5,000 pounds of load-leveling support with air adjustability from 5 to 100 PSI. The system helps maintain proper ride height when towing or hauling heavy loads.
The kit is recommended for most 3/4-ton and 1-ton pickups and SUVs with leaf springs. However, you must verify fitment for your specific vehicle before purchasing. Check both sides of the frame rail for obstructions (specifically propane lines) that may prevent mounting on the outside of the frame rail. If obstructions are present, kit 57131 (which mounts under the frame to the axle) may be required instead.
Any type of load assist product could affect brake performance on vehicles equipped with a rear brake proportioning valve. Air Lift recommends checking with your vehicle dealer before installing this product. 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 system performance.
Normal Ride Height is the distance between the bottom edge of the wheel-well and the center of the hub with the vehicle in its "as delivered" condition. It is critical to measure and record this before installation because the air spring assembly must be positioned to maintain this height. During installation, you must restore the vehicle to this original ride height before securing the brackets. This ensures proper air spring alignment and function.
The kit requires a minimum of 7.5 inches of clearance between the frame and the tire for a fully inflated air spring. You must measure this distance before installation to confirm your vehicle has adequate space. If clearance is insufficient, the kit may not be suitable for your vehicle.
The distance between the upper and lower brackets must be between 4.5 and 6.5 inches at normal ride height. If the measurement is not within this range, or if the stock u-bolts hit the lower bracket, use the two spacer bars (part M) provided in the kit under the lower bracket to achieve the correct distance.
Install the air fitting (part E) finger tight plus 1 and 1/2 turns using a 7/16" open-end wrench. Tighten only on the metal hex nut; do not overtighten. The fitting is precoated with sealant, so additional sealant is not needed for initial installation.
Yes, drilling is required. You must drill 3/8" holes in the frame rail to mount the upper bracket. Before drilling, you must check both sides of the frame rail for interference such as hydraulic lines, gas lines, and electrical wires. Do not drill any holes without first confirming there are no obstructions. The manual requires center-punching the hole location first and drilling one hole at a time, checking bracket alignment after each hole.
Yes. You must drill 5/16" holes to install the inflation valves. Popular mounting locations include the wheel well flanges, license plate recess in the bumper, under the gas cap access door, or through the license plate. Choose a location with enough clearance around the valve for an air chuck to be easily applied.
All upper bracket frame bolts (part I) must be tightened to 44 lb-ft. Use a torque wrench to ensure proper tightness. This torque applies to all four frame bolts that secure the upper bracket to the frame rail.
Required tools include: 1/2" and 9/16" open-end or box wrenches; crescent wrench; ratchet with 9/16" and 1/2" deep well sockets; very sharp 5/16" drill bits; heavy-duty drill; torque wrench; hose cutter, razor blade, or sharp knife; hoist or floor jacks; safety stands; safety glasses; air compressor or compressed air source; and spray bottle with dish soap/water solution. A 7/16" open-end wrench is also needed for the air fitting.
The kit includes: 2 air springs (58494); 2 upper brackets (07475); 2 lower brackets (03102); 4 roll plates (11967); 2 air fittings (21837); 8 bolts 3/8"-24 X 7/8" (17203); 8 lock washers 3/8" (18427); 16 flat washers 3/8" SAE (18444); 8 frame bolts 3/8"-16 X 1.5" (17159); 8 oversized flat washers 3/8" (18447); 16 nylon lock nuts 3/8"-16 (18435); 8 carriage bolts 3/8"-16 X 7" (17163); 8 clamp/spacer bars (01426); 1 air line assembly (20086sub); 6 tie straps (10466); 2 valve caps (21230); 2 rubber washers 5/16" (21234); 2 flat washers 5/16" (18405); 2 star washers (18411); and 4 hex nuts 5/16" (21233).
Route the air line along the frame to the fitting on the air spring, maintaining at least 6 inches of clearance from the exhaust system. Avoid sharp bends and edges. Use zip ties to secure the air line to fixed points along the chassis. Tie straps should be tight but must not pinch the air line. Leave at least 2 inches of slack to allow for movement that might pull on the air line. Do not bend 1/4" hose at a radius less than 1" or 3/8" hose at a radius less than 1.5".
Use a sharp knife or hose cutter to make clean, square cuts. Do not use scissors or wire cutters, as these tools may deform the air line and cause leaks. Do not cut at an angle. Leave approximately 12 inches of extra air line. Insert the air line into the push-to-connect fitting by wiggling the hose back and forth while inserting to ensure the hose bottoms out in the fitting for a good seal.
The maximum air pressure is 100 PSI. Never exceed this pressure. However, the actual air pressure needed depends on load and your vehicle's GVWR. Do not exceed your vehicle's maximum gross vehicle weight rating regardless of air spring pressure or other load assist.
The recommended minimum air pressure is 5 PSI. However, the system can safely be run at zero air pressure when the vehicle is unladen (no load). For loaded vehicles (with heavy bed load, trailer, or both), maintain at least 25 PSI. Operating below the minimum air spring pressure will void the Air Lift warranty.
No. Installing air springs will not change the GAWR (Gross Axle Weight Rating), GCWR (Gross Combined Weight Rating), or GVWR (Gross Vehicle Weight Rating) of your vehicle. You must not exceed the maximum load listed in your vehicle's owner's manual or on the Safety Compliance Certification Label. Exceeding the GVWR is dangerous and voids the Air Lift warranty.
Before operating, perform these checks: (1) Clearance test—inflate to 75-90 PSI and verify at least 1/2" clearance from tire, brakes, frame, shock absorbers, and brake cables; (2) Leak test—inflate to 75-90 PSI and check all connections for leaks; (3) Heat test—ensure at least 6" clearance from heat sources; (4) Fastener test—recheck all bolts for proper torque; (5) Road test—drive 10 miles and recheck clearance, fasteners, and leaks; (6) Overnight leak-down test—recheck pressure after 24 hours; (7) Thirty-day or 500-mile test—recheck the system and all fasteners.
Inflate the air springs to 30 PSI. Spray all connections and inflation valves with a solution of 1 part liquid dish soap and 4 parts water. Leaks are easily spotted by looking for bubbles in the soapy water. After testing, deflate the springs to the minimum pressure required to restore normal ride height (not lower than 5 PSI). A 2-4 PSI loss after initial installation is normal. If loss exceeds 5 PSI, retest for leaks.
Check air pressure weekly. Always maintain normal ride height and never inflate beyond 100 PSI. Periodically check all fasteners for tightness and inspect air springs for signs of rubbing; realign if necessary. If a leak develops, use soapy water solution to check all air line connections and the inflation valve core. Occasionally spray the air springs with a garden hose to remove mud, sand, gravel, or debris. If the vehicle will be on a hoist for a prolonged period, support the axle with jack stands to reduce tension on the air springs.
If the air springs are properly installed and maintained, they can last indefinitely. Proper maintenance includes checking air pressure weekly, maintaining normal ride height, keeping the system free of leaks, and periodically checking fasteners for tightness.
Loaded vehicles (with heavy bed load, trailer, or both) require at least 25 PSI. The springs support approximately 40 pounds of load (combined on both springs) for each 1 PSI of pressure. When increasing load, always adjust air pressure to maintain normal ride height. Loads carried behind the axle (including tongue loads) require more leveling force (pressure) than those carried directly over the axle. As much as a 50 PSI difference between sides is not uncommon for uneven loads such as water, fuel, or appliances.
Check for leaks by performing a leak test on the air line connections, the threaded connection into the air spring, and all fittings in the control system. Use a soapy water solution (1 part dish soap, 4 parts water) to identify leaks. Make sure air lines are seated properly in connectors. If the air line is compromised, trim 1 inch off the end with a clean, square cut and reinsert into the fitting. If the threaded fitting leaks, tighten it another half turn. If it still leaks, deflate the spring, remove the fitting, re-coat the threads with thread sealant, and reinstall.
Look for a kink or fold in the air line. Replace any air line that has been kinked. Kinked lines prevent proper air flow and can develop leaks. Inspect the entire length of the air line from the valve to the air spring fitting.
Deflate the spring and remove the air line by pulling the collar against the fitting and pulling firmly on the line. Trim 1 inch off the end of the air line with a sharp knife or hose cutter, ensuring the cut is clean and square. Do not use scissors or wire cutters. Reinsert the air line into the push-to-connect fitting, wiggling it back and forth to ensure it bottoms out for a good seal.
First, check the valve core by tightening it with a valve core tool. If that does not resolve the leak, check the air line by removing it from the barbed fitting. Cut the air line 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 these steps do not resolve the problem, contact Air Lift customer service at (800) 248-0892.
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 significant effort. An on-board air compressor system allows for hassle-free control and is optional. Learn more about Air Lift control systems at www.airliftcompany.com/products/compressor-systems.
Yes, 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. When raising the vehicle by the frame for any reason, ensure the system is at minimum pressure (5 PSI) to reduce tension on suspension and brake components. On-board leveling systems do not require deflation or disconnection.
The kit is designed for 3/4-ton and 1-ton pickups and SUVs with leaf springs. Before purchasing, check both sides of your frame rail for obstructions (especially propane lines). If obstructions prevent outside mounting, kit 57131 (under-frame mount) may be required. Also verify your vehicle does not have a rear brake proportioning valve, or consult your dealer. Contact Air Lift at (800) 248-0892 for fitment confirmation.
You need a minimum of 7.5 inches between the frame and tire for a fully inflated air spring. Measure this before installation to confirm your vehicle has adequate space.
Essential tools: 1/2" and 9/16" wrenches, ratchet with deep well sockets, very sharp 5/16" drill bits, heavy-duty drill, torque wrench, hose cutter or sharp knife, hoist or floor jacks, safety stands, safety glasses, air compressor, and spray bottle with dish soap/water solution.
Minimum recommended pressure is 5 PSI (can run at 0 PSI unladen); loaded vehicles require at least 25 PSI. Maximum pressure is 100 PSI. Never exceed your vehicle's GVWR regardless of air pressure.
Inflate to 75-90 PSI and verify 1/2" clearance from tire, brakes, frame, and shock absorbers. Check all connections for leaks using soapy water. Verify at least 6" clearance from exhaust. Recheck all bolt torque. Road test for 10 miles and recheck clearance and leaks. Check pressure again after 24 hours.
Check air pressure weekly. Maintain normal ride height and never exceed 100 PSI. Periodically check fasteners for tightness and inspect for rubbing. If a leak develops, use soapy water to identify the source. Spray springs occasionally with a garden hose to remove debris.
Cause: Improperly installed air line, air line with holes or cracks, or compromised fitting seal. Solution: Perform a leak test on the air line connections, the threaded connection into the air spring, and all fittings in the control system. Check that air lines are seated in connectors. Inspect fittings with soapy water. Trim the hose or re-seal the fitting. Ensure lines are cut straight. If the threaded fitting leaks, tighten it another half turn. If it still leaks, deflate the spring, remove the fitting, re-coat threads with thread sealant, and reinstall by hand-tightening as much as possible, then use a wrench for an additional two turns.
Cause: Kink or fold in the air line. Solution: Inspect the entire length of the air line from the valve to the air spring fitting. Replace any air line that has been kinked, as kinked lines prevent proper air flow and can develop leaks.
Deflate the spring and remove the air line by pulling the collar against the fitting and pulling firmly on the line. Trim 1 inch off the end of the air line using a sharp knife or hose cutter, ensuring the cut is clean and square. Do not use scissors or wire cutters, as these deform the line and cause leaks. Reinsert the air line into the push-to-connect fitting, wiggling it back and forth to ensure it bottoms out for a good seal.
First, check the valve core by tightening it with a valve core tool. If the leak persists, check the air line by removing it from the barbed fitting. Cut the air line 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 these steps do not resolve the problem, contact Air Lift customer service at (800) 248-0892.
