The Air Lift LoadLifter 7500 XL Ultimate is a rear load-leveling air spring kit for the 2016-2025 Chevrolet Silverado 3500HD and GMC Sierra 3500HD. Its pair of 7-inch double-convoluted bellows deliver up to 7500 lbs of leveling capacity and are air-adjustable from 5 to 100 PSI to stop squat sway and bottoming-out when towing or hauling. An internal closed-cell jounce bumper absorbs road shock and lets the springs be run safely at zero pressure. The underframe-mount design works with most in-bed hitches and requires 9 inches of clearance from the frame to the tire.
