Product Description
The AIR LIFT 88338 LoadLifter 5000 Ultimate Air Spring Kit is engineered to provide maximum load support and towing stability for the 2011-2019 Chevrolet Silverado and GMC Sierra 2500HD/3500HD trucks. Designed for heavy-duty hauling and towing, this advanced air suspension system delivers up to 5,000 pounds of load-leveling capacity to eliminate rear-end squat, improve ride stability, and maintain proper suspension geometry under heavy loads.
The LoadLifter 5000 Ultimate system features Air Lift’s exclusive internal jounce bumper, which creates a three-stage ride comfort system. This design absorbs shock, prevents bottoming out, and protects the suspension even if air pressure drops. Adjustable air pressure from 5-100 PSI allows drivers to dial in the exact suspension support needed for towing trailers or hauling heavy cargo.
Constructed with heavy-duty two-ply reinforced commercial-grade rubber air springs and corrosion-resistant mounting brackets, the AIR LIFT 88338 kit is built to withstand demanding towing conditions. The kit includes air springs, brackets, air lines, fittings, and mounting hardware for a straightforward bolt-on installation that dramatically improves ride quality and load handling.

What is the advantage of the Ultimate series?
The Ultimate series includes an internal jounce bumper that prevents bottoming out and provides a smoother ride even if the air springs lose pressure.
Can this kit work with fifth-wheel hitches?
Yes. The AIR LIFT 88338 is compatible with most side-mounted fifth-wheel hitch setups commonly used for towing large trailers.
Can I add an onboard compressor system?
