Tow With Confidence And Ride With Comfort

If your truck squats under load or feels unstable while towing, the Air Lift 88338 LoadLifter 5000 Ultimate Air Spring Kit is the upgrade you’ve been looking for. Designed for 2011–2019 Silverado and Sierra 2500HD/3500HD models, this kit helps restore proper ride height and keeps your truck level and controlled whether you're towing a fifth wheel or hauling heavy gear in the bed. With up to 5,000 pounds of load-leveling support, it drastically improves comfort, safety, and control under load. The internal jounce bumper adds a cushion of support, so even if air pressure drops, you won’t bottom out or get that harsh, jarring ride. That means more confidence on rough roads, better braking response, and improved steering feel when it matters most. Installation is straightforward with all necessary hardware included, and it replaces your factory jounce bumpers for a clean, OE-like fit. Whether you're chasing comfort, capability, or both, this air spring kit has your back.

Engineered To Handle Heavy Loads With Zero Compromise

The Air Lift LoadLifter 5000 Ultimate Kit is built to maximize load support and ride control for heavy-duty towing and hauling on 2011–2019 GM 2500HD and 3500HD trucks. Each air spring is constructed like a high-strength tire with reinforced 2-ply fabric for durability, while the built-in closed-cell urethane jounce bumper provides progressive load absorption even with zero air pressure. This eliminates harsh bottom-outs and allows the vehicle to maintain safe ride quality, even during sudden compression events. The kit includes exclusive upper and lower roll plates that protect the air springs from contact with sharp frame edges and increase overall load capacity by up to 10 percent. It’s a fully bolt-on system and includes all brackets, air lines, Schrader valves, and a detailed instruction manual. Once installed, the system requires no regular maintenance and is backed by a lifetime warranty that covers every component in the kit. It also includes a 60-day money-back guarantee, giving peace of mind to truck owners who demand both performance and reliability.
