Product Description
The AIR LIFT 88398 LoadLifter 5000 Ultimate Air Spring Kit is designed to improve load support, towing stability, and ride quality for the 2005-2010 Ford F-250 and F-350 Super Duty 4WD trucks. Engineered for serious towing and hauling applications, this premium air suspension system delivers up to 5,000 pounds of load-leveling capacity to eliminate rear-end squat and maintain proper suspension geometry when carrying heavy loads.
The LoadLifter 5000 Ultimate system includes Air Lift’s exclusive internal jounce bumper, creating a three-stage ride comfort system that absorbs road shock and prevents bottoming out even if air pressure drops. Adjustable air pressure from 5-100 PSI allows drivers to fine-tune suspension support depending on trailer weight or payload demands.
Constructed with heavy-duty double convoluted rubber air springs and corrosion-resistant mounting brackets, the AIR LIFT 88398 kit is built to handle demanding towing environments. The kit installs between the frame and rear leaf springs and includes air springs, mounting brackets, airlines, fittings, and installation hardware for a straightforward bolt-on upgrade.

Can I install an onboard compressor system?
Yes. Air Lift compressor systems such as WirelessAir or WirelessONE allow drivers to adjust air pressure from inside the cab.
