The Air Lift LoadLifter 5000 Ultimate is a rear load-leveling air spring kit for 1999-2007 Chevrolet Silverado and GMC Sierra 1500 half-ton trucks. It works alongside the factory leaf springs to add up to 5,000 lbs of load-leveling capacity, keeping the truck level and stable whether loaded or unloaded. The closed-cell urethane jounce bumper sealed inside each air spring absorbs shock and lets the kit run safely at zero air pressure. Air pressure is adjustable from 5 to 100 PSI to match the load.
