The LoadLifter 7500 XL Ultimate is an air spring load-leveling system designed for 3/4-ton and 1-ton pickups and SUVs with leaf springs. It uses commercial-grade double-convolute air springs manufactured with layers of rubber and cords to provide up to 7,500 pounds (3,402 kg) of load-leveling support. The system is adjustable from 5–100 PSI (0.34–7 BAR), allowing you to maintain level ride height when carrying heavy loads.
Kit 57554 is designed for Ford SD F-250/F-350 4WD SRW (Single Rear Wheel) models. The kit is not compatible with dual rear wheel (DRW) configurations. If you have a single rear wheel truck, this kit should fit, but confirm your truck's specific model year and configuration with Air Lift customer service at (800) 248-0892 before purchasing.
The kit supports three axle configurations: 3.5-inch axle (adapter part 11688), 4-inch axle (adapter part 11690), and Tremor models (adapter part 03911). You must select the correct lower leg adapter for your vehicle's axle diameter. Refer to Table 1 in the installation guide to identify which adapter your vehicle requires.
Required tools include: metric and standard open-end box wrenches, ratchet with metric and standard sockets, 5/16-inch drill bit and drill, torque wrench, metric and standard hex key wrenches, 9/16-inch crow's foot adapter, 9/16-inch ratchet combo wrench, two mid-size adjustable wrenches, hose cutter or sharp knife, hoist or floor jack, two safety stands, safety glasses, air compressor or compressed air source, and a spray bottle with dish soap and water solution.
The manual does not specify whether the battery must be disconnected. Contact Air Lift customer service at (800) 248-0892 for guidance on this step.
Raise the vehicle using a hoist or floor jack and support it with safety stands positioned so that the axle can be safely lowered away from the frame. This clearance is necessary to position the air spring assemblies between the axle and frame. Never work under a vehicle supported only by a jack.
The first step is to unbolt and remove the jounce bumper assembly from under the frame on both the driver's (left) and passenger's (right) sides. Then remove the four clip-in studs by prying on the hinged end with a screwdriver to release them from the frame.
Line up the holes in the frame rail with the threaded nuts so that a bolt can be installed through them. A flat-tipped screwdriver works well for positioning the universal nuts (part T) into place. Ensure the nuts are seated properly before proceeding.
The M10-1.5 x 35 mm button-head cap screws (part N) securing the upper frame bracket (part D) to the frame must be torqued to 38 lb.-ft. (52 Nm).
1. Install the swivel elbow fitting (part V) into the top of the air spring finger-tight, then tighten an additional one and a half turns. Place a roll plate (part J) on top. 2. Insert 3/8-inch carriage bolts (part DD) into the square holes and secure the upper air spring bracket (part E) using 3/8-inch hex bolts (part W), lock washers (part X), and flat washers (part R). Push the bracket as far forward as possible and torque to no more than 20 lb.-ft. (27 Nm). 3. Flip the assembly over and place another roll plate on the bottom. 4. Insert a carriage bolt through the lower bracket (part B) and attach the lower bracket cup (part C) with a serrated flange lock nut (part U), leaving it loose enough for the bracket to move freely. 5. Insert two 3/8-inch x 10-inch carriage bolts through the remaining square holes in the lower bracket. 6. Attach the lower bracket assembly to the air spring with hex bolts, lock washers, and flat washers, pushing as far forward as possible, and torque to no more than 20 lb.-ft. (27 Nm).
The 3/8-inch hex bolts (part W), lock washers (part X), and flat washers (part R) securing the upper air spring bracket (part E) to the air spring must be torqued to no more than 20 lb.-ft. (27 Nm).
The 3/8-inch hex bolts (part W), lock washers (part X), and flat washers (part R) securing the lower bracket assembly to the air spring must be torqued to no more than 20 lb.-ft. (27 Nm).
Select the appropriate adapter based on your vehicle's axle diameter: use the Tremor adapter (part H) for Tremor models, the 3.5-inch adapter (part I) for 3.5-inch axles, or the 4-inch adapter (part P) for 4-inch axles. Attach the selected adapter with a 3/8-inch x 1-inch carriage bolt (part DD) and 3/8-inch serrated flange lock nut (part U). Push the adapter against the lower bracket and torque the hardware to 16 lb.-ft. (14 Nm).
1. Pry out the top left, bottom left, and top right ABS harness mounts from the brake line/ABS harness/vent tube bracket on the axle. 2. Pull the left wiring harness down and attach the harness mount to the ABS/Brake junction bracket (part M), then attach this bracket to the existing bracket on the axle using a 3/8-inch hex cap screw (part Q), flat washer (part R), and serrated flange lock nut (part U), torqued to 31 lb.-ft. (42 Nm). 3. Install a zip tie around the left harness. 4. Bend the upper brake line/ABS harness/vent tube bracket using two adjustable wrenches to make clearance for the lower air spring roll plate. 5. Install a P-clamp (part LL) around the right ABS harness and attach it to the inside hole on the bent bracket using a 1/4-inch hex screw (part MM), two flat washers (part OO), and a nylon lock nut (part NN).
Yes. You must bend the upper brake line/ABS harness/vent tube bracket to make clearance for the lower air spring roll plate. Hold the bottom of the bracket with an adjustable wrench and bend the top back and down using another adjustable wrench. This is a required modification to prevent interference with the air spring assembly.
Driver's (left) side: Remove the rearward fifth wheel bracket hardware if equipped. Locate the two M10 bolts holding the brake line bracket to the frame, unbolt them, and pull the bracket away. Install the 50 mm set screw (part Y) into the rearward threaded hole, leaving about 30 mm (1.20 inches) protruding. Set the upper brace (part G) over the set screw against the frame, ensuring the large slot lines up with the fifth wheel bracket hole. Set the stock brake line bracket over the set screw on top of the brace. Thread the M10 serrated flange lock nut (part CC) onto the set screw. Reinstall factory fifth wheel hardware or use the supplied 5/8-inch hardware (parts Z, AA, BB) through the frame and brace, leaving loose. Passenger's (right) side: Remove and discard the O2 sensor clip if present. Remove factory fifth wheel hitch hardware if equipped and use it or the supplied 5/8-inch hardware to attach the upper frame brace (part F) to the frame, leaving loose. Always use the reinforced hole in the frame, not the open gap between frame walls.
With the vehicle supported by safety stands, drop the axle or raise the body so the assemblies can be positioned between the axle and frame. Set both the driver's (left) and passenger's (right) side assemblies so that the lower bracket cup rests on the jounce bumper strike plate. Push the lower bracket so it is flush against the leaf spring stack with both flanges locked around the stock U-bolts. If you have a sway bar, insert the carriage bolts through the clamp bar (part A) as you set the assemblies into position.
Install the U-bolt (part L) around the stock U-bolt/leaf spring assembly and insert it through the topmost holes in the lower bracket main plates. Cap with a 3/8-inch flat washer (part R) and 3/8-inch nylon lock nuts (part KK). Snug the bolts evenly, just enough to hold the lower bracket main plate flush against the stock U-bolts. Then finish tightening by torquing to 10 lb.-ft. (14 Nm).
The U-bolt (part L) hardware must be torqued to 10 lb.-ft. (14 Nm).
Ensure the 90-degree fittings are pointing inboard toward the center of the vehicle. While raising the axle or lowering the body, align the previously installed upper frame bracket carriage bolts (including the one on the air spring bracket) with the air spring bracket/frame brace holes so the carriage bolts protrude. Cap all carriage bolts with 3/8-inch serrated flange lock nuts (part U). Snug the bolts first, then torque to 31 lb.-ft. (42 Nm).
If using the supplied 5/8-inch hardware (parts Z, AA, BB), torque to 150 lb.-ft. (203 Nm). If using the stock fifth wheel hardware that was removed, torque to 180 lb.-ft. (244 Nm).
The M10 serrated flange lock nut (part CC) on the driver's (left) side brace must be torqued to 37 lb.-ft. (50 Nm).
If your vehicle has a sway bar, set the lower clamp bars (part A) over the carriage bolts located under the axle. Attach with 3/8-inch flat washers (part R) and nylon lock nuts (part KK). Evenly torque the lower clamp bar hardware to 16 lb.-ft. (22 Nm). For sway bar applications, it is acceptable to tighten the front carriage bolt hardware more than the rear to gain clearance on the sway bar. A 9/16-inch crow's foot adapter may be necessary to properly torque the hardware.
Yes. On vehicles with a sway bar, you must cut the front carriage bolt just below the nut so it does not contact the sway bar.
After cutting the front carriage bolt on sway bar vehicles, torque the nut (part U) to 32 lb.-ft. (43 Nm) on both sides.
The axle vent tube must be zip-tied to one of the brake soft lines to keep it out of the way of the air spring assembly.
Once the lower brackets are secured, ensure the brake line is not rubbing against the lower bracket carriage bolt on the right (passenger's) side. Pull or push the hard brake line away to gain clearance if necessary.
If the left ABS wiring harness under the right (passenger's) side roll plate is rubbing, zip-tie it down to secure it in place.
Yes. You must drill a 5/16-inch (8 mm) hole in your chosen location for each Schrader valve. Recommended locations are inside the fuel tank filler door, inside rear wheel wells, or in the license plate or rear bumper area.
Cut the air line in half using a razor blade or hose cutter, making clean, square cuts. Do not use scissors or wire cutters, as they will damage the air line.
Keep at least 6 inches (152 mm) of clearance between all air lines and the exhaust system. Avoid sharp bends and edges. The minimum bend radius for the air line is 1 inch (25 mm).
Use zip ties to secure the air line to fixed points along the chassis. Do not pinch or kink the air line. Leave at least 2 inches (51 mm) of slack in the air line to allow for any movement that might pull on the line. The minimum bend radius for the air line is 1 inch (25 mm).
Attach the metal heat shield to the exhaust where it is closest to the air spring. Slide the air line thermal sleeve over the nylon air line and place it where the air line is closest to the exhaust. Maintain at least 1/2 inch (13 mm) of dead air space between the shield and exhaust. Double hose clamps if necessary.
The maximum air pressure is 100 PSI (7 BAR). Never inflate beyond this pressure. Although the air springs are rated at this maximum, the actual air pressure needed depends on your load and gross vehicle weight rating.
The minimum recommended pressure is 5 PSI (0.34 BAR).
Check air pressure weekly to ensure the system is operating at the correct pressure for your load.
Use a soapy water solution to check all air line connections and the inflation valve core before deflating and removing the air spring. This will help you identify the source of the leak.
No. Do not exceed your vehicle's maximum gross vehicle weight rating (GVWR) or payload rating as indicated by the vehicle manufacturer. Although the air springs provide up to 7,500 pounds of load-leveling support, they do not increase your vehicle's weight capacity.
Inflate the air springs to 40–60 PSI (2.8–4.1 BAR) and ensure there is at least 1/2 inch (13 mm) clearance from anything that might rub against each air spring. Be sure to check the tire, brakes, frame, shock absorbers, and brake cables.
Inflate the air springs to 40–60 PSI (2.8–4.1 BAR) and check all connections for leaks using a soapy water solution. All leaks must be eliminated before the vehicle is road tested.
Ensure there is sufficient clearance from heat sources, at least 6 inches (152 mm) for air springs and air lines. If a heat shield was included in the kit, install it. If there is no heat shield but one is required, call Air Lift customer service at (800) 248-0892.
After 500 miles (800 km), recheck all bolts for proper torque to ensure nothing has loosened during initial use.
After the initial tests are complete, road test the vehicle with the air springs inflated to recommended driving pressures. Drive the vehicle 10 miles (16 km) and recheck for clearance, loose fasteners, and air leaks.
Kit 57554 fits Ford SD F-250/F-350 4WD SRW (Single Rear Wheel) models only. Confirm your truck's configuration with Air Lift customer service at (800) 248-0892.
You need wrenches, sockets, a 5/16-inch drill, torque wrench, hex keys, adjustable wrenches, hose cutter, hoist or floor jack, safety stands, safety glasses, and an air compressor or compressed air source.
Yes. You must drill a 5/16-inch (8 mm) hole for each Schrader valve. You must also bend the brake line bracket to make clearance for the air spring assembly.
Maximum air pressure is 100 PSI (7 BAR). Never exceed this pressure. Do not exceed your vehicle's GVWR or payload rating.
Upper frame bracket: 38 lb.-ft. (52 Nm). Upper and lower air spring brackets: 20 lb.-ft. (27 Nm). Lower leg adapter: 16 lb.-ft. (14 Nm). U-bolt: 10 lb.-ft. (14 Nm). Carriage bolts to frame: 31 lb.-ft. (42 Nm). Frame brace (supplied hardware): 150 lb.-ft. (203 Nm); (factory hardware): 180 lb.-ft. (244 Nm). Driver's side brace M10 nut: 37 lb.-ft. (50 Nm). Lower clamp bar: 16 lb.-ft. (22 Nm).
Keep at least 6 inches (152 mm) clearance between all air lines and the exhaust system. Minimum bend radius for air lines is 1 inch (25 mm).
Perform a clearance test at 40–60 PSI, a leak test with soapy water, verify 6-inch heat clearance, recheck fastener torque after 500 miles, and road test for 10 miles checking clearance, fasteners, and leaks.
Check air pressure weekly. Always maintain normal ride height. Never inflate beyond 100 PSI (7 BAR). If an air leak develops, use soapy water to locate it before deflating and removing the air spring.
Pull or push the hard brake line away to gain clearance. This adjustment is made after the lower brackets are secured and before final road testing.
Zip-tie the left ABS wiring harness down to secure it in place and prevent it from rubbing on the roll plate.
Use a soapy water solution to check all air line connections and the inflation valve core. The leak will appear as bubbles in the soapy water. Once identified, deflate and remove the air spring to repair or replace the leaking component.
