Yes, the Air Lift LoadLifter 5000 ULTIMATE with internal jounce bumper 88395 (Part #BBCG88395) is designed to fit the 2011-2016 Ford F-250 Super Duty.
The Air Lift LoadLifter 5000 ULTIMATE with internal jounce bumper 88395 (Part #BBCG88395) 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- and 1-ton pickups and SUVs with leaf springs. It provides up to 5,000 pounds of load leveling support and allows air pressure adjustment from 5 to 100 PSI. The system uses reinforced, commercial-grade convolute bellows manufactured with layers of rubber and cords to control growth, similar to tire construction. It is used in rear applications and some front applications on vehicles with leaf springs.
Yes, kits 57395 and 88395 are designed for Ford Super Duty single- and dual-rear wheel 2WD models. However, the manual does not specify which model years or body styles are compatible. Contact Air Lift customer service at (800) 248-0892 or (517) 322-2144 (outside USA/Canada) to confirm fitment for your specific vehicle.
The two kits are visually identified by their roll plates. The standard LoadLifter 5000 (57395) has zinc-plated steel roll plates and black nylon air lines. The LoadLifter 5000 Ultimate (88395) has black powder-coated roll plates and black nylon air lines. Both kits use the same installation procedure. The air springs differ: 57395 uses part 11951 roll plates and 58437 air springs, while 88395 uses part 11967 roll plates and 58496 air springs.
Yes, the kit can be installed on vehicles with fifth-wheel hitches. If your truck has the standard factory Reese fifth-wheel hitch, use the supplied 1/2" hardware as directed. If you have an aftermarket fifth-wheel hitch with side plates along the frame, you may need to reuse the existing hardware or drill a 1/2" hole through the plate using the frame slot as a template. If the aftermarket hitch has no attaching hardware on the side where the frame slot is, drilling is required. Consult the manual's driver's and passenger's side brace installation sections for specific hardware options.
Required tools include: metric and standard open-end box wrenches (set), ratchet with metric and standard sockets (set), drill with 5/16" drill bit, torque wrench, hose cutter or razor blade or sharp knife, hoist or floor jack, two safety stands, safety glasses, air compressor or compressed air source, and spray bottle with dish soap/water solution. A thin-wall socket is recommended for accessing the driver's side mounting hardware.
Yes. The jounce bumpers must be removed from under the frame over the axle. Wire brush the stud on the jounce bumper and use penetrating oil to aid removal. The socket size for the nut is typically 15 mm. The existing jounce bumper holes are later used to mount the upper bracket assembly.
Yes, on the driver's (left) side, you may need to disconnect the wiring harness from the frame rail to gain clearance for the upper brace. Also push out the harness connector holding electrical lines to the gas/DEF tank bracket to improve socket and bolt access. On gas engine models, emissions lines running along the inside of the frame rail must be relocated by carefully pushing out the line holder from the frame above the axle. Remove any emissions/fuel line and electrical wire loom retaining clips forward or rearward of the axle to aid in positioning the lines once the upper brace is installed. These components are reconnected after the braces are secured.
Drilling may be required depending on your fifth-wheel hitch configuration. If you have an aftermarket fifth-wheel hitch with side plates along the frame that does not have existing attaching hardware on the side where the frame slot is, you must drill a 1/2" hole through the plate using the slot in the frame as a template. Drill the hole as far to the rear of the slot as possible. It may be necessary to mark and remove the outer bracket from the frame to drill the hole correctly, then reattach it. You must also drill a 5/16" (8 mm) hole for the Schrader valve installation location. Clear any electrical or hard lines from the drilling area to avoid damage.
Yes. Cut the air line in half using a hose cutter, razor blade, or sharp knife. Make clean, square cuts. Do not use scissors or wire cutters. After cutting, 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" (51 mm) of slack in the air line to allow for movement. The minimum bend radius for the air line is 1" (25 mm). Keep at least 6" (152 mm) of clearance between all air lines and the exhaust system.
The air spring is attached to both the lower bracket and upper bracket using 3/8"-24 x 7/8" hex cap screws (EE) with 3/8" lock washers (FF) and 3/8" flat washers (V). Torque these bolts to no more than 20 lb.-ft. (27 Nm). This applies to both the driver's (left) side and passenger's (right) side assemblies.
The 3/8"-16 x 1 1/4" carriage bolts (O) that attach the upper bracket to the frame brace should be torqued to 15 lb.-ft. (20 Nm). These bolts are capped with 3/8" flat washers (V) and 3/8" nylon lock nuts (U).
The axle clamp bar bolts (the 3/8"-16 x 7" carriage bolts with 3/8" flat washers and 3/8" nylon lock nuts) should be torqued to 16 lb.-ft. (22 Nm). Tighten the hardware evenly until it touches the axle. Do not pinch the hard brake line on the passenger's (right) side while tightening.
The leaf spring U-bolt hardware (3/8" flat washers and 3/8" nylon lock nuts) should be torqued to 10 lb.-ft. (14 Nm). Once tight, the upper and lower brackets will not be parallel and may look out of alignment, but this is normal due to the bracket mount design.
The swivel elbow fitting (Y) should be installed into the top of the air spring finger tight, then tightened an additional 1 1/2 turns. No torque wrench value is specified for this fitting.
The manual provides three suggested locations for the Schrader valve: (A) inside the fuel tank filler door, (B) inside the rear wheel wells, or (C) license plate or rear bumper area. Choose the location that works best for your vehicle and drill a 5/16" (8 mm) hole if necessary. The valve is installed in the chosen location after the air line has been cut and routed.
The maximum air pressure is 100 PSI (7 BAR). Although the air springs are rated at this maximum, the actual air pressure needed depends on load and gross vehicle weight rating. Never inflate beyond 100 PSI. Always maintain normal ride height.
The minimum recommended pressure is 5 PSI (0.34 BAR). Check air pressure weekly and always maintain normal ride height.
Do not exceed the vehicle's maximum gross vehicle weight rating (GVWR) or payload rating as indicated by the vehicle manufacturer. Do not exceed 100 PSI inflation pressure. Check air pressure weekly. 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. Keep at least 6" (152 mm) of clearance between all air lines and the exhaust system. Ensure at least 1/2" (13 mm) clearance from the air spring sleeves to anything that might rub, including tires, brakes, frame, shock absorbers, and brake cables.
Perform the following checks in order: (1) Clearance test—inflate to 40-60 PSI and verify at least 1/2" (13 mm) clearance from tires, brakes, frame, shock absorbers, and brake cables. (2) Leak test—inflate to 40-60 PSI and check all connections for leaks; all leaks must be eliminated before road testing. (3) Heat test—ensure at least 6" (152 mm) clearance from heat sources; install the heat shield if included. (4) Fastener test—recheck all bolts for proper torque. (5) Road test—drive 10 miles (16 km) at recommended driving pressures and recheck for clearance, loose fasteners, and air leaks.
Check air pressure weekly. Always maintain normal ride height and never inflate beyond 100 PSI (7 BAR). The actual air pressure needed depends on load and gross vehicle weight rating.
If the system develops an air leak, use 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 to identify the leak location. All leaks must be eliminated before the vehicle is road tested. If you cannot locate or repair the leak, contact Air Lift customer service at (800) 248-0892 or (517) 322-2144 (outside USA/Canada).
Yes. After driving the vehicle 10 miles (16 km), recheck all bolts for proper torque as part of the post-installation road test. The manual does not specify a retorque interval beyond this initial check.
Yes, both kits are designed for Ford Super Duty single- and dual-rear wheel 2WD models. Confirm your specific year and body style with Air Lift customer service at (800) 248-0892.
The kit provides up to 5,000 pounds of load leveling support. However, do not exceed your vehicle's maximum gross vehicle weight rating (GVWR) or payload rating as specified by the manufacturer.
Perform clearance, leak, heat, and fastener tests at 40-60 PSI. Then road test for 10 miles and recheck clearance, fasteners, and leaks. Ensure 1/2" clearance from air springs and 6" from exhaust.
No, this is normal. Once the leaf spring U-bolt hardware is tightened to 10 lb.-ft. (14 Nm), the upper and lower brackets will not be parallel and may look out of alignment. This condition is acceptable because of the way the lower bracket and upper bracket mounts are designed. Some variance from one unit to another is considered normal.
It may be necessary on some models to not tighten the axle clamp bar evenly on the passenger's (right) side so that the clamp bar will clear the hard brake line. Adjust the tightening sequence to avoid pinching the brake line while still achieving the 16 lb.-ft. (22 Nm) torque specification.
Use 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 to identify the leak location. All leaks must be eliminated before road testing. If you cannot locate or repair the leak, contact Air Lift customer service at (800) 248-0892 or (517) 322-2144 (outside USA/Canada).
