The Air Lift LoadLifter 5000 Ultimate Air Spring Kit (88354) is designed to provide dependable load-leveling support for Ford F-250 and F-350 Super Duty 4WD trucks with single rear wheels (SRW). With up to 5,000 lbs. of load-leveling capacity, this rear underframe-mounted kit helps eliminate sag, trailer sway, rough ride, and bottoming out when towing or hauling heavy loads.

This Ultimate-series kit features Air Lift’s exclusive internal jounce bumper, allowing the air springs to safely operate at zero PSI while still absorbing shock and protecting your suspension. Fully adjustable from 5–100 PSI, the LoadLifter 5000 Ultimate delivers a stable, level ride whether loaded or unloaded.

Installation is straightforward with a no-drill, bolt-on design that works with most in-bed hitch systems. Backed by Air Lift’s limited lifetime warranty and 60-day ride satisfaction guarantee, this kit is a proven upgrade for serious towing and hauling.

Note: Fits SRW models only. Does not fit dual rear wheel (DRW) or commercial cab & chassis applications.
