The Air Lift LoadLifter 5000 is a rear load-leveling air spring kit for the Chevrolet Silverado / GMC Sierra 1500 Trail Boss 2019-2026. Rated up to 5000 lbs of load-leveling capacity and adjustable from 5 to 100 PSI - the air springs mount between the frame and existing suspension to eliminate squat - sag - trailer sway - and bottoming out when towing or hauling.
