Product Description
The AIR LIFT 57575 LoadLifter 7500XL Air Spring Kit is designed for serious towing and hauling with 2001-2010 Chevrolet Silverado and GMC Sierra 2500HD and 3500HD trucks. Built specifically for heavy-duty diesel pickups, this premium suspension upgrade delivers up to 7,500 pounds of load-leveling support, eliminating rear suspension squat and dramatically improving towing stability.
The LoadLifter 7500XL system uses massive 7-inch double-bellows air springs that provide roughly 20% more air volume than the standard LoadLifter 5000 system. This increased air capacity allows the suspension to support larger loads with less air pressure while maintaining excellent ride quality. Adjustable air pressure from 5-100 PSI lets drivers fine-tune suspension support for different towing or hauling conditions.
An internal jounce bumper protects the suspension from bottoming out when driving with heavy loads or low air pressure. Reinforced roll plates and corrosion-resistant brackets increase durability while distributing weight more evenly across the rear suspension. The kit includes air springs, mounting brackets, airlines, inflation valves, and installation hardware for a complete load support system.
