Yes, the Air Lift LoadLifter 5000 ULTIMATE with internal jounce bumper 88385 (Part #BBCG88385) is designed to fit the 2015-2020 Ford F-150.
The Air Lift LoadLifter 5000 ULTIMATE with internal jounce bumper 88385 (Part #BBCG88385) fits 2015-2020 Ford F-150 models. The 2020 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 88385 (Part #BBCG88385) Refer to the included instructions for installation details. Basic hand tools are typically all you need.
Yes, these kits are designed for Ford F150 4-Wheel Drive. However, the manual does not specify which model years are compatible. Contact Air Lift customer service at (800) 248-0892 to confirm fitment for your specific truck year.
Required tools include: standard and metric wrenches and sockets, ratchet, torque wrench, 7/32" hex-key wrench, hose cutter or sharp knife, cutoff wheel or hacksaw, Christmas tree puller, hoist or floor jack, two safety stands, safety glasses, air compressor, and spray bottle with dish soap/water solution.
Yes. The manual states 'Professional mechanic skills are required to complete the installation of this kit.' The installation involves cutting the brake line bracket, torquing fasteners to specific values, and routing air lines with precise clearance requirements.
Drilling is required only if you choose to install Schrader valves in locations that do not already have holes. You must drill a 5/16" (8 mm) hole for the valve. The brake line bracket must also be cut approximately 1.375" (35 mm) from the edge using a cutoff wheel, air reciprocating saw, or hacksaw.
Upper bracket flanged nut (O): 20 lb.-ft. (27.1 Nm). Lower bracket carriage bolts with clamp bars (A) and serrated flange nuts (O): 16 lb.-ft. (21.7 Nm). U-bolt (P) serrated flange nuts: 10 lb.-ft. (13.6 Nm). Air spring mounting hardware (top and bottom): no more than 20 lb.-ft. (27.1 Nm). Braided stainless steel air line fittings: finger-tight plus 1/6 of one full turn (2 wrenches required).
The maximum air pressure is 100 PSI (7 BAR). The minimum recommended pressure is 5 PSI (0.34 BAR). Do not exceed 100 PSI, as this may damage the vehicle or cause unsafe operation. Actual pressure needed depends on load and your vehicle's GVWR.
Perform a clearance test at 40–60 PSI, a leak test at 40–60 PSI, a heat test (minimum 6 inches from heat sources), a fastener recheck after 500 miles, and a 10-mile road test. Inflate to recommended driving pressure and recheck clearance, fasteners and leaks after the road test.
Check air pressure weekly. Always maintain normal ride height and never inflate beyond 100 PSI (7 BAR). If an air leak develops, use a soapy water solution to check all air line connections and the inflation valve core before deflating and removing the air spring.
The LoadLifter 5000 series provides up to 5,000 pounds (2,268 kg) of load-leveling support. The air springs are adjustable from 5–100 PSI (0.34–7 BAR) and are manufactured with reinforced, commercial-grade single or double convolute bellows with layers of rubber and cords that control growth.
Standard LoadLifter 5000 (kit 57385): zinc-plated steel roll plates and black nylon air lines. LoadLifter 5000 Ultimate (kit 88385): black powder-coated roll plates and black nylon air lines. LoadLifter 5000 Ultimate Plus (kit 89385): stainless steel roll plates, braided stainless steel air lines, and stainless steel air spring mounting hardware. Air Lift also offers upgrade kits 52300 (braided stainless steel air line and fittings) and 52301 (stainless steel roll plates, hardware, and braided air lines).
No. The factory jounce bumpers must be removed as part of the installation. They are removed using a 13mm socket and extension (the bolts have blue sealant and may require a small impact). The M10 flange head bolt (Q) is then installed in the locations created by the jounce bumpers, with approximately 1/2" (13 mm) gap between the bolt flange and the chassis.
Yes. The brake line tabs attached to both sides of the leaf spring perches must be removed using a 10mm socket. Additionally, the plastic clip from the ABS line on the right side of the axle must be removed. The wiring harness and ABS line must be moved out of the way, and a small portion of the brake line bracket must be cut (approximately 1.375" or 35 mm from the edge) for proper clearance to fit the lower bracket.
The air spring (E) is flipped upside down with the air fitting port facing down. The roll plate (F), spacer (if required), and lower bracket (B) are placed on the air spring with all holes lined up. The hex head screw (N or I) with flat washer (J) and lock washer (K) is threaded finger-tight. The air fitting port must face inboard of the vehicle, and the air spring must be mounted forward on the bracket. Everything is kept loose enough so the air spring can slide front to back until final alignment.
The spacer (G) is required if the distance between the upper and lower brackets at ride height measures 6.75"–7.50" (171–191 mm). To determine this, temporarily set the lower bracket (B) into position and lower the truck body/frame to ride height. Measure from the bottom mounting surface of the lower bracket to the top mounting surface of the upper bracket. If the measurement is within this range, install the spacer. If not, use the included shorter hardware (N) without the spacer.
The air fitting port on the air spring must face inboard of the vehicle (toward the center). The air spring must be mounted forward on the bracket. The air fittings (H) are installed finger-tight plus 1 1/2 turns after the assembly is flipped upright.
The upper bracket (C for left, D for right) is pushed up against the frame so the flanged bolt (Q) passes through the keyway in the bracket. When the bracket is against the frame, push the bracket outward to lock into the keyway. Thread the flanged nut (O) and tighten, ensuring the vertical portion of the bracket is touching the side of the frame. Torque the bolt to 20 lb.-ft. (27.1 Nm).
Carriage bolts (M) are placed through the front hole on the lower brackets. The assemblies are positioned on the axle with the tabs wrapping around the leaf spring perch. Self-threading screws (L) are installed on the spring perch (front and rear). Two additional carriage bolts are installed, and clamp bars (A) are placed over the carriage bolts with serrated flange nuts (O). The assembly is torqued to 16 lb.-ft. (21.7 Nm).
There should be approximately 1/8" (3 mm) gap between the top of the air spring assembly and the upper bracket. This is achieved by raising the axle enough to allow the top of the air spring to move around slightly after the top roll plates are installed.
The U-bolt (P) is placed over the top of the frame and the ends are passed through the two holes on the front side of the upper bracket. Serrated flange nuts are threaded on both sides and torqued to 10 lb.-ft. (13.6 Nm). Ensure proper clearance between the U-bolt and brake lines to prevent damage.
After the U-bolt is installed, the air spring assembly is aligned by sliding it forward or backward. Ensure clearance to objects around the air spring, then torque the mounting hardware on the top and bottom to no more than 20 lb.-ft. (27.1 Nm). Ensure proper clearance away from sharp edges and components to prevent damage to the wiring harness and ABS line.
The wiring harness and ABS line must be zip-tied (BB) out of the way so they do not rub against anything. This prevents damage during vehicle operation. The manual notes that 2019 vehicles will have a wiring harness, but other model years may not.
Schrader valves can be installed in three locations: (A) inside the fuel tank filler door, (B) inside rear wheel wells, or (C) license plate or rear bumper area. For LoadLifter 5000 Ultimate Plus kits, the recommended location is the rear bumper area or license plate. A 5/16" (8 mm) hole must be drilled if the chosen location does not already have one.
Nylon air lines should be routed along the top of the frame, forward of the axle, then down to the fitting. The air line must be cut in half with clean, square cuts using a razor blade or hose cutter (not scissors or wire cutters). The air line thermal sleeve must be installed over the air line on the passenger's (right) side before inserting into the fitting. Zip ties should secure the air line to fixed points along the chassis. The minimum bend radius is 1" (25 mm), and at least 2" (50 mm) of slack must be left to allow for movement.
Braided stainless steel air lines must be routed to the rear of the vehicle through one of the openings between the upper coil spring mount and the frame, then back to the rear where the Schrader valves will be mounted. Zip ties should secure the air line to fixed points along the chassis every 6"–8" (150–200 mm). At least 2" (50 mm) of slack must be left to allow for movement. The air line hex nut is tightened finger-tight, then 1 additional flat (1/6 of one full turn) using 2 wrenches. Do not overtighten. The braided stainless steel air line cannot be trimmed; excess must be coiled and secured in an area where it will not be susceptible to damage.
Keep at least 6" (150 mm) of clearance between all air lines and the exhaust system. Avoid sharp bends and edges. A heat shield must be attached to the exhaust where it is closest to the passenger's (right) side air spring, with 1/2" (13 mm) dead air space between the shield and exhaust.
At least 1/2" (13 mm) clearance must be maintained from anything that might rub against each air spring sleeve. During the clearance test at 40–60 PSI, check the tire, brakes, frame, shock absorbers and brake cables. Ensure proper clearance away from sharp edges and components to prevent damage to the wiring harness and ABS line.
At least 6" (152 mm) of clearance must be maintained between air springs and air lines and heat sources. If a heat shield was included in the kit, it must be installed. If there is no heat shield but one is required, contact Air Lift customer service at (800) 248-0892.
No. Do not exceed the maximum gross vehicle weight rating (GVWR) or payload rating as indicated by the vehicle manufacturer. Although the air springs are rated at a maximum inflation pressure of 100 PSI (7 BAR), the actual air pressure needed depends on load and GVWR. Exceeding these ratings may cause safety issues and possible damage to the vehicle.
A clearance test is performed after installation by inflating the air springs to 40–60 PSI (2.8–4.1 BAR) and checking that there is at least 1/2" (13 mm) clearance from anything that might rub against each sleeve. Be sure to check the tire, brakes, frame, shock absorbers and brake cables. This test must be completed before the vehicle is road tested.
A leak test is performed by inflating the air springs to 40–60 PSI (2.8–4.1 BAR) and checking all connections for leaks using a soapy water solution. All leaks must be eliminated before the vehicle is road tested. If the system develops an air leak after installation, use a soapy water solution to check all air line connections and the inflation valve core before deflating and removing the air spring.
All bolts should be rechecked for proper torque after 500 miles of driving. This is part of the post-installation inspection process to ensure the system remains secure.
If the system develops an air leak, use a soapy water solution to check all air line connections and the inflation valve core. If a leak is found, it must be repaired before the vehicle is used. If the leak cannot be located or repaired, deflate and remove the air spring and contact Air Lift customer service at (800) 248-0892.
Measure approximately 1.375" (35 mm) from the edge of the brake line bracket; this may vary depending on the truck. Use the dashed line shown in the manual as a reference. Make the cut using a cutoff wheel, air reciprocating saw, or hacksaw. Use caution while cutting to ensure the brake line and wire harness have proper clearance to avoid damage.
Nylon air lines should be cut in half with clean, square cuts using a razor blade or hose cutter. Do not use scissors or wire cutters, as these will produce bad cuts that may cause leaks or fitting problems.
No. Braided stainless steel air lines cannot be trimmed. Any excess air line must be coiled and secured in an area where it will not be susceptible to damage.
Common parts in all three kits include: 2 air springs (E, part 58496), 4 roll plates (F), 8 hex head screws (I), 8 lock washers (J), 8 flat washers (K), 4 hex head screws (N), and 2 stainless steel braided air lines (HH). Kit 57385 includes: 2 clamp bars (A), 2 lower brackets (B), 1 upper left bracket (C), 1 upper right bracket (D), 2 lower spacers (G), 2 air fittings (H), 8 flat washers (K), 4 self-threading screws (L), 4 carriage bolts (M), 4 hex head screws (N), 8 serrated flange nuts (O), 2 U-bolts (P), 2 M10 flange bolts (Q), 1 air line assembly (AA), 6 zip ties (BB), 2 lock washers (CC), 2 rubber washers (DD), 2 M8 flat washers (EE), 4 hex nuts (FF), and 2 valve caps (GG).
The manual does not explicitly state whether factory fasteners are reused. However, factory jounce bumpers are removed and replaced with M10 flange head bolts (Q). Factory brake line tabs are removed. The manual does not indicate that other factory fasteners are reused in the assembly.
Use a spray bottle with a soapy water solution to check all air line connections and the inflation valve core. Spray the solution on the connections and look for bubbles, which indicate a leak. If a leak is detected, it must be repaired before the vehicle is road tested. If the leak cannot be located or repaired, deflate and remove the air spring and contact Air Lift customer service at (800) 248-0892.
During the clearance test at 40–60 PSI (2.8–4.1 BAR), check that there is at least 1/2" (13 mm) clearance from anything that might rub against each sleeve, including the tire, brakes, frame, shock absorbers and brake cables. If rubbing is detected, the air spring assembly must be realigned by sliding it forward or backward. After realignment, torque the mounting hardware on the top and bottom to no more than 20 lb.-ft. (27.1 Nm) and recheck clearance.
After 500 miles of driving, recheck all bolts for proper torque. If fasteners are found to be loose, retighten them to the specified torque values: upper bracket flanged nut (O) to 20 lb.-ft. (27.1 Nm), lower bracket carriage bolts with clamp bars (A) to 16 lb.-ft. (21.7 Nm), U-bolt (P) to 10 lb.-ft. (13.6 Nm), and air spring mounting hardware (top and bottom) to no more than 20 lb.-ft. (27.1 Nm). Recheck fasteners again after the 10-mile road test.
