Air Lift LoadLifter 5000 Ultimate Rear Air Spring Kit with Cradle - Chevrolet Silverado 2500HD ZR2 / GMC Sierra 2500HD AT4X 2024-2026

The Air Lift LoadLifter 5000 Ultimate is a rear load-leveling helper air spring kit for the 2024-2026 Chevrolet Silverado 2500HD ZR2 and GMC Sierra 2500HD AT4X (4WD). It adds up to 5,000 lbs of leveling capacity with double-bellows air springs adjustable from 5-100 PSI to control squat, trailer sway, and bottoming out when towing or hauling. An internal closed-cell jounce bumper lets the springs run safely at zero PSI, and the included Air Spring Cradles let the springs detach from the lower bracket for full suspension extension off-road. The underframe kit bolts on with no frame drilling and works with most in-bed hitches.
