Air Lift LoadLifter 5000 Ultimate Rear Air Spring Kit - Toyota Tundra 2007-2021

The Air Lift LoadLifter 5000 Ultimate is a rear load-leveling air helper spring kit for the 2007-2021 Toyota Tundra. It works with the factory leaf springs to add up to 5000 lbs of leveling capacity and control squat, sway, and bottoming-out when towing or hauling. Air pressure is adjustable from 5 to 100 PSI to match the load, and an internal closed-cell urethane jounce bumper replaces the factory bumper so the springs run safe at zero PSI. The kit includes 2 air springs, brackets, air lines, a Schrader valve, roll plates, and all mounting hardware, and requires no frame drilling.
