The LoadLifter 5000 load support kit for lifted 2017-2022 Ford F-250/F-350 SRW 4WD offers up to 5,000 lbs. of load-leveling capacity while helping to eliminate squat, trailer sway, and body roll and backed by our limited lifetime warranty.
Offering up to 5,000 pounds of load-leveling capacity, the LoadLifter 5000 kit for a lifted 2017-2022 Ford F-250/F-350 SRW 4WD from Air Lift will make towing and hauling a comfortable and stress-free experience. Fully adjustable from 5-100 PSI, our air springs are the perfect partner for your vehicle, helping to eliminate problems frequently faced when towing and hauling, such as squat, poor headlight aim, trailer sway, body roll, and bottoming out. This side-mounted kit is designed to fit lifted trucks. It will not fit lifts that alter or replace factory leaf springs or lifts that alter frame-to-leaf distance. Because of its side mount design, this kit will work with leaf spring block spacer-style lifts, which are commonly used on this platform. Each kit has upper and lower roll plates to protect the air springs from sharp edges. The air springs are built similarly to tires, reinforced with 2-ply fabric for maximum strength. All end caps are made with an ultra-high-strength nylon composite formula, as strong as steel but much lighter and corrosion-proof. Installing the kit is simple, requiring only common hand tools and no frame drilling. The LoadLifter 5000 kit has clear, easy-to-follow instructions and an underframe design that works with most in-bed hitches. As the leader in air suspension products for over 75 years, Air Lift is committed to delivering quality load support products that fit, work, and last. To ensure the highest quality, longevity, and customer satisfaction, the key suspension components, including the air springs and all hardware, have all been torture-tested to 1 million cycles on our hydraulic test rig. With a limited lifetime warranty, a 60-day ride satisfaction guarantee, and a dedicated in-house customer service team, you can purchase this kit with peace of mind. Do not exceed the vehicle’s gross vehicle weight rating (GVWR).

Kit 57409 is designed for Ford F-250 & F-350 4WD Single Rear Wheel models. The manual does not specify model years. Contact Air Lift customer service at (800) 248-0892 or email service@airliftcompany.com to confirm fitment for your specific year and configuration.
If your F-250 has Ford 5th wheel brackets mounted to the side of the frame, you must remove the hardware that holds the brackets to the frame during installation. The manual does not specify whether the brackets are permanently removed or can be reinstalled after the air springs are mounted.
Required tools include: hacksaw or handheld grinder with cut-off wheel; tin snips or box cutter knife; standard and metric open-end or boxed-end wrenches; standard and metric regular and deep-well sockets; 15/16" ½ drive socket; 15/16" open-end or boxed-end wrench; 3/8" and ½" drive ratchet; small and large capacity torque wrench; hose cutter, razor blade or sharp knife; hoist and axle lift or floor jack; two tire chocks; two safety stands; safety glasses; air compressor or compressed air source; and spray bottle with dish soap/water solution.
The kit includes: 2 lower brackets (03965), 1 upper LH bracket (07729), 1 upper RH bracket (07840), 4 spacer bars (11182), 4 roll plates (11951), 2 air springs (58437), 2 1/4" 90-degree swivel air fittings (21837), 8 3/8"-24 X 7/8" hex cap screws (17203), 8 3/8" lock washers (18427), 16 3/8" flat washers (18444), 4 3/8"-16 X 5½" U-bolts (10561), 4 3/8"-16 X 2" U-bolts (10594), 4 5/8"-11 X 4½" hex cap screws (17348), 8 3/8"-16 nylon lock nuts (18435), 4 5/8"-11 nylon lock nuts (18548), 8 5/8" flat washers (18449), 1 air line assembly (20086), 6 zip ties (10466), 2 valve caps (21230), 2 star washers (18411), 2 rubber washers (21234), 2 M8 flat washers (18501), and 4 5/16" hex nuts (21233).
The manual does not mention battery disconnection. This kit is a mechanical air suspension system with no electrical components requiring battery disconnection.
The 3/8" hex cap screws (H) that attach the upper brackets (B & C) to the air springs must be torqued to no more than 20 lb.-ft. (27 Nm).
Install the 1/4" 90-degree swivel air fittings (G) into the top of the air spring finger-tight, then tighten an additional 1½ turns. Do not over-tighten.
The 5/8" hex cap screws (M) that attach the upper brackets to the frame must be torqued to 185 lb.-ft. (250 Nm).
The lower bracket mounting hardware must be torqued to no more than 20 lb.-ft. (27 Nm) during initial alignment. After alignment is complete, the U-bolt hardware is torqued to 16 lb.-ft. (22 Nm) for both frame-contact and non-frame-contact overload models.
U-bolt fasteners must be torqued to 16 lb.-ft. (22 Nm). This applies to both the 3/8"-16 X 5½" U-bolts (K) used on non-frame-contact models and the 3/8"-16 X 2" U-bolts (L) used on frame-contact overload models.
Yes. You must drill a 5/16" (8 mm) hole for each Schrader valve location. The manual recommends choosing locations inside the fuel tank filler door, inside rear wheel wells, or in the license plate or rear bumper area. The manual does not specify the number of valves or whether drilling is required on all installations.
On models equipped with an inner fender liner, you must trim out a small section where the fender comes in contact with the roll plates on top of the air spring. Use tin snips or a box cutting knife to trim the area as needed. The manual warns to use extreme caution with a box cutting knife to avoid injury. Not all models have an inner fender liner.
For non-frame-contact overload models only: use a hacksaw or grinder to trim the rear, inside leftover length of the U-bolt off to just above the nylon lock nut on both sides of the vehicle. For frame-contact overload models, there is no need to trim the U-bolts.
Use zip ties (BB) 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 any movement that might pull on the air line. 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. Avoid sharp bends and edges.
Make clean, square cuts with a razor blade or hose cutter when cutting the air line (AA). Do not use scissors or wire cutters, as they will damage the line.
Never inflate the air springs beyond 100 PSI (7 BAR). The minimum recommended air pressure is 5 PSI (0.34 BAR). The actual air pressure needed depends on your load and gross vehicle weight rating.
Maintain at least 6" (152 mm) of clearance between air springs and air lines and any heat sources. 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.
The LoadLifter 5000 air springs are rated to provide up to 5,000 pounds (2,268 kg) of load-leveling support. However, you must not exceed the maximum gross vehicle weight rating (GVWR) or payload rating as indicated by the vehicle manufacturer.
Perform the following checks before operating: (1) Clearance test—inflate to 40–60 PSI and verify at least ½" (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—verify at least 6" (152 mm) clearance from heat sources. (4) Fastener test—after 500 miles (800 km), recheck all bolts for proper torque. (5) Road test—drive 10 miles (16 km) and recheck for clearance, loose fasteners and air leaks.
Check air pressure weekly to maintain proper system operation and load support.
Use a soapy water solution to check all air line connections and the inflation valve core to locate the leak. Do not deflate and remove the air spring until you have identified the source of the leak.
After 500 miles (800 km), recheck all bolts for proper torque to ensure the system remains secure.

You need a hoist and axle lift or floor jack, torque wrench, hacksaw or grinder, tin snips or box cutter, compressed air source, and standard/metric wrenches and sockets. Safety stands and tire chocks are also required.
Yes, you must drill a 5/16" (8 mm) hole for each Schrader valve. On models with an inner fender liner, you may also need to trim the fender where it contacts the air spring roll plates.
Upper bracket to air spring: 20 lb.-ft. (27 Nm). Upper bracket to frame: 185 lb.-ft. (250 Nm). Lower bracket and U-bolt fasteners: 16 lb.-ft. (22 Nm). Lower bracket initial alignment: 20 lb.-ft. (27 Nm).
Maximum air pressure is 100 PSI (7 BAR). Maintain at least 6" (152 mm) clearance from exhaust and heat sources, and at least ½" (13 mm) clearance from tires, brakes, frame and shock absorbers.
Inflate to 40–60 PSI and verify clearance from all components. Check for leaks at all connections. Verify 6" clearance from heat sources. After 500 miles, recheck bolt torque. Road-test for 10 miles and recheck clearance, fasteners and leaks.
Check air pressure weekly. Always maintain normal ride height. Never exceed 100 PSI. If a leak develops, use soapy water to locate it before deflating. Recheck all bolts after 500 miles.
Use a spray bottle with a soapy water solution to check all air line connections and the inflation valve core. Bubbles will form at the location of any leak. Do not deflate and remove the air spring until you have identified the source of the leak.
