The Air Lift LoadLifter 5000. 57291 (Part #BBCG57291) fits 1999-2007 Ford F-250 models. The 2007 model year is the last year covered by this part number. For newer models, check for an updated version.
The Air Lift LoadLifter 5000. 57291 (Part #BBCG57291) fits the following vehicles: 1999-2007 Ford F-250; 1999-2007 Ford F-350. Always verify your specific year, make, and model before ordering.
Yes, the Air Lift LoadLifter 5000. 57291 (Part #BBCG57291) is designed to fit the 1999-2007 Ford F-250.
The Air Lift LoadLifter 5000. 57291 (Part #BBCG57291) Refer to the included instructions for installation details. Basic hand tools are typically all you need.
The LoadLifter 5000 is an air suspension system designed for ¾ and 1 ton pickups and SUVs with leaf springs. It uses reinforced, commercial-grade convolute bellows (manufactured like a tire with layers of rubber and cords) to provide up to 5,000 lbs of load leveling support. Air pressure is adjustable from 5 to 100 PSI, allowing you to maintain normal ride height under varying loads. The kit is also used in motorhome rear and some motorhome front applications.
Yes, kit 57291 is designed for 1999-2007 Ford F-250/F-350 in both 2WD and 4WD configurations with leaf springs. The kit includes two air springs, brackets, hardware and air lines. If your truck has a B&W hitch, special modifications are required (see B&W hitch applications section).
Yes, but special modifications are required. For B&W part number 1199R with the hitch in the 49" position only, you must trim ¼ inch from the bottom of the center flange on the side plate and front cross member. You must also grind a slight chamfer on the back of the front mounting leg of the upper brackets to clear the bend radius of the large flange on the B&W side plate. For 2005 models, you will also need to remove the top rear shock bracket rivet on the passenger side only to mount the upper bracket.
Yes. On 2005 models, it is necessary to remove the top rear shock bracket rivet on the passenger side only to provide a mounting hole for the upper bracket. This is a one-time removal; the rivet does not need to be replaced.
Required tools include: hoist or floor jacks, 2 safety stands, safety glasses, torque wrench, 5/16" and 7/16" and 9/16" open-end or box wrenches, crescent wrench, ratchet with 9/16", metric and ½" deep well sockets, 3/8" and 5/16" drill bits (very sharp), heavy duty drill, hose cutter or sharp knife, air compressor or compressed air source, and spray bottle with dish soap/water solution.
The kit includes: 2 air springs (part 58437), driver and passenger side upper brackets (parts 07437, 07438), 4 roll plates (11951), 2 lower brackets (03102), 2 swivel elbow fittings (21837), 6 zip ties (10466), 2 flat washers 5/16" (18405), 2 lock washers 5/16" (18411), 2 valve caps (21230), 4 hex nuts (21233), 2 rubber washers (21234), 16 inches of air line (20086), 8 bolts 3/8" (17203), 8 lock washers 3/8" (18427), 20 flat washers 3/8" (18444), 4 U-bolts 3/8" x 3.5 x 4.5 (10583), 4 spacer bars 3" (01426), 4 U-bolts 3/8"-16 x 2 (10594), 10 Nyloc nuts 3/8" (18435), 2 washer head bolts 3/8" (17159), 2 large washers 5/16" x 3/8" (18447), and 1 line clamp (10465).
Raise the vehicle on a hoist or floor jacks and support it with at least 2 safety stands. Remove the wheels. Establish normal ride height. Ensure there is a minimum of 8 inches of clearance between the tire and frame. Wear safety glasses during installation. If your vehicle has a B&W hitch, follow the special applications instructions before proceeding.
1. Set a roll plate on both ends of the air spring with the radiused (rounded) edge facing the air spring so it is seated in both roll plates. 2. Install a 90° swivel air fitting finger tight plus 1½ turns (do not overtighten). 3. Place the driver side upper bracket on top of the bellow and roll plate with legs facing down. 4. Set the air spring on the driver side lower bracket and align the two holes in the base of the air spring with the two outer slots in the top of the lower bracket. 5. Loosely attach the lower bracket using flat washers, lock washers and hex head bolts. The flange on the lower bracket must face the outside (tire-side) of the vehicle. Repeat for the passenger side.
Set the air spring over the axle. Slide one 3-inch spacer bar under the front leg and one under the rear leg of the lower bracket. Attach the lower bracket to the leaf using the provided U-bolts. Torque the U-bolts to 16 ft/lbs. The attachment method depends on whether your vehicle has frame contact overloads or a regular leaf stack.
Align the upper bracket so it is parallel to the lower bracket. Torque the 3/8" hardware to 40 ft/lbs. If using B&W hitch applications, torque the ¾" hardware to 90 ft/lbs. For non-B&W installations, use the existing factory hardware.
The upper bracket is slotted so the air spring can be adjusted forward and back. The lower bracket is slotted so the air spring can be adjusted in and out. Using these slots, adjust the air spring so it is perpendicular to both surfaces. Tighten the top and bottom mounting hardware to no more than 10 ft/lbs.
Yes. You must drill a 5/16" hole at your chosen location for the inflation valve. Popular locations include the wheel well flanges, license plate recess in bumper, under the gas cap access door, or through the license plate itself. Ensure there is enough clearance around the inflation valve for an air chuck.
Use a hose cutter, razor blade, or sharp knife to cut the air line. A clean, square cut is essential 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. When cutting, leave approximately 12 inches of extra air line after the final cut.
1. Place a 5/16" nut and star washer on the air valve. Leave enough 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. Approximately ½" of valve should be exposed after installation to easily apply a pressure gauge or air chuck. 2. Push the inflation valve through the hole. 3. Use the rubber washer, flat washer, and another 5/16" nut on the back side. 4. Tighten the nuts to secure the assembly in place.
Route the air line along the frame to the air fitting on the air spring. Keep at least 6 inches of clearance between the air line and heat sources such as exhaust pipes, muffler, or catalytic converter. Avoid sharp bends and edges. Use plastic tie straps to secure the air line to fixed, non-moving points along the chassis. Tie straps should be tight but not pinch the air line. Leave at least 2 inches of slack to allow for any movement that might pull on the air line.
Cut the air line leaving approximately 12 inches of extra air line. Ensure the cut is clean and square. Insert the air line into the 90° swivel fitting. This 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 inside the fitting.
Attach the supplied clamp around the emergency brake cable and secure it to the lower bracket using the previously removed stock bolt. Tighten securely. Cut the existing emergency brake cable bracket close to the cable.
Inflate the air spring to 30 PSI and spray all connections and inflation valves with a solution of 1 part liquid dish soap and 4 parts 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 (no less than 5 PSI). 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.
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, ensuring the cut is clean and square. Reinsert the air line into the push-to-connect fitting. If it still leaks, check the threaded connection by tightening the swivel fitting another ½ 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, then use a wrench for an additional two turns.
Check the valve core by tightening it with a valve core tool. If that does not resolve the leak, check the air line connection by removing the air line from the barbed type fitting. Do not cut the air line completely off, as this will nick the barb and render the fitting useless.
Complete the installation checklist: verify all fasteners are tight, check for leaks at 30 PSI using soapy water, and deflate to minimum pressure (5 PSI). Then complete the post-installation checklist: (1) Clearance test—inflate to 60 PSI and ensure at least ½ inch clearance around each bellow away from tire, brake drum, frame, shock absorbers and brake cables. (2) Leak test—inflate to 60 PSI and check all connections with soapy water. (3) Heat test—ensure at least 6 inches clearance from heat sources. (4) Fastener test—recheck all bolts for proper torque and re-torque after 100 miles. (5) Road test—drive 10 miles at 25 PSI (50 PSI if loaded) and recheck for clearance, loose fasteners and leaks.
No. Installing air springs will not change the weight ratings (GAWR, GCWR and/or GVWR) of your vehicle. You must not exceed the maximum load listed in your vehicle's owner's manual. Exceeding the GVWR is dangerous and voids the Air Lift warranty.
The minimum air pressure is 5 PSI and must be maintained at all times. The minimum pressure keeps the air spring in shape, ensuring it will move throughout its travel without rubbing or wearing on itself. The maximum air pressure is 100 PSI. Never inflate beyond 100 PSI. Failure to maintain correct minimum pressure will void the warranty.
Check the air pressure weekly. Always maintain normal ride height by adjusting air pressure as needed. When increasing load, always adjust the air pressure to maintain normal ride height. Remember that loads carried behind the axle (including tongue loads) require more leveling force (pressure) than those carried directly over the axle.
Recheck the air spring system after 30 days or 500 miles, whichever comes first. 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 all fasteners for tightness. Re-torque axle strap carriage bolt lock nuts to 16 ft/lbs after 100 miles. Check air pressure weekly and maintain normal ride height at all times.
If the air springs are properly installed and maintained, they can last indefinitely. Proper maintenance includes checking air pressure weekly, maintaining normal ride height, avoiding pressure exceeding 100 PSI, preventing bottoming out and rubbing, and following all installation instructions.
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 of time, support the axle with jack stands to take the tension off the air springs. If you need to raise the vehicle by the frame, make sure the system is at minimum pressure (5 PSI) to reduce tension on the suspension and brake components.
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. Air Lift offers optional on-board compressor systems for convenience, but they are not required for operation.
Always add air to the springs in small quantities, checking the pressure frequently. Sleeves require less air volume than a tire and inflate quickly. Start with the vehicle level or slightly above. When in doubt, always add air. For motorhomes, start with 50-100 PSI in the rear because it can be safely assumed that it is heavily loaded.
Pressure determination comes down to three things: level vehicle, ride comfort, and stability. (1) Level vehicle—if headlights are shining into the trees or the vehicle is leaning to one side, raise the air pressure to level it. (2) Ride comfort—if the vehicle has a rough and harsh ride, try different pressures to determine the best comfort. (3) Stability—prioritize stability over a perfectly level and comfortable ride. Stability issues include roll control, bounce, dive during braking and sponginess; these usually require an increase in pressure. 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; as much as a 50 PSI difference is not uncommon.
If you suspect the air bags have bottomed out, increase the pressure. Bottoming out occurs when the air spring compresses fully and the bellow contacts the frame or other components. Increasing pressure will prevent this condition.
If the vehicle rocks and rolls, adjust the air pressure to reduce movement. This is a stability issue that usually requires an increase in pressure. You may need to maintain different pressures on each side of the vehicle depending on load distribution.
If the front of the vehicle dives while braking, increase the pressure in the front air bags, if equipped. This is a stability issue that requires an increase in pressure to improve braking performance.
Use a soapy water solution to check all air line connections and the inflation valve core before deflating and removing the spring. Spot leaks by looking for bubbles in the soapy water. Check the air line connections, the threaded connection into the air spring, and all fittings in the control system. Inspect the air lines to ensure none are pinched (tie straps may be too tight). Loosen or replace the strap and replace leaking components. Inspect the air line for holes and cracks and replace as needed. Look for a kink or fold in the air line and reroute as needed. If these steps do not solve the problem, call Air Lift at (800) 248-0892 for assistance.

The maximum air pressure is 100 PSI. Never inflate beyond 100 PSI. The minimum pressure is 5 PSI and must be maintained at all times. Do not exceed your vehicle's GVWR.
Inflate to 60 PSI and check for ½ inch clearance around each bellow. Test for leaks with soapy water. Ensure 6 inches clearance from heat sources. Recheck all bolt torque. Road test at 25 PSI (50 PSI if loaded) for 10 miles and recheck clearance and leaks.
Check air pressure weekly. Recheck the system after 30 days or 500 miles. Re-torque U-bolts after 100 miles. Check for rubbing or abrasion and tighten all fasteners. Maintain minimum 5 PSI pressure at all times.
Deflate the spring and remove 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 until it bottoms out (approximately 9/16" should be inside). If it still leaks, tighten the swivel fitting another ½ turn. If it continues to leak, 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.
Check the valve core by tightening it with a valve core tool. If that does not resolve the leak, check the air line connection by removing the air line from the barbed type fitting. Do not cut the air line completely off, as this will nick the barb and render the fitting useless.
Use a soapy water solution to check all air line connections, the threaded connection into the air spring, and all fittings. Inspect the air lines to ensure none are pinched (tie straps may be too tight). Loosen or replace the strap. Inspect the air line for holes and cracks and replace as needed. Look for a kink or fold in the air line and reroute as needed. If these steps do not solve the problem, it is possibly caused by a failed air spring (either a factory defect or an operating problem). Call Air Lift at (800) 248-0892 for assistance.
If the vehicle's headlights are shining into the trees or the vehicle is leaning to one side, it is not level. Raise the air pressure to correct either of these problems and level the vehicle. Check that all fasteners are tight and that the air springs are properly seated in the brackets. If the problem persists, check for leaks or uneven loading.
If the vehicle has a rough and harsh ride, it may be due to either too much pressure or not enough. Try different pressures to determine the best ride comfort. Start by adjusting pressure in small increments and test drive the vehicle. If the problem persists, check that all fasteners are tight and that the air springs are properly seated in the brackets.
