Overview
The AirLift LoadLifter 5000 Ultimate air spring kit, part number AIR88350, is a rear air spring kit for 2020–2022 Ford F-250 and F-350 Super Duty trucks. It adds an internal jounce bumper to the LoadLifter 5000 design, which AirLift says helps absorb shock even with zero air pressure in the spring.
The air springs add rear support to the existing suspension for hauling. The kit provides up to 5,000 lbs of load leveling, and it is designed to keep the rear of the truck level under heavy loads. It is a direct-fit rear kit for the Super Duty trucks covered by its fitment.
Key features
- Internal jounce bumper for shock absorption at zero air pressure

- Rear application
- Boosts the existing suspension for hauling

Air spring maintenance and load
Air springs are rubber bellows that hold air, and their condition decides how well the rear suspension supports a load. Check the bellows for cracks, abrasion and bulges, especially where they rub against brackets or the frame. Air lines should be routed clear of heat and moving parts, with clamps where the tubing could chafe.
Leaks show up as a slow sag overnight or a compressor that runs more often than usual. A soapy water test on fittings and the bellow seams will find most leaks without special tools. Air pressure should be set with the truck loaded, since the support level depends on pressure and load together.

- Test fittings for leaks with soapy water
