When a heavy load or trailer drops your rear suspension, steering and braking can feel off. The Air Lift LoadLifter 5000 air springs add up to 5,000 lbs of load-leveling support to keep your ride height where it should be. By distributing weight evenly across all four wheels, they reduce strain on your factory suspension and help maintain proper headlight aim. Even under a full load, your truck stays level, stable, and ready for the next climb or braking zone.
Every haul is different, and this setup adjusts to match. The LoadLifter 5000 lets you fine-tune each spring from 5 to 100 psi using the manual inflation valves included in the kit. Inflate both sides equally for front-to-back leveling or independently for side-to-side balance when hauling uneven loads. Whether you’re towing heavy or driving unloaded, it’s easy to get the comfort and control you want with simple air adjustments.
Load support only matters if it lasts. Each air bag is made from 2-ply, fabric-reinforced rubber with corrosion-proof Zytel nylon endcaps that are lighter and stronger than steel. Air Lift’s exclusive upper and lower roll plates add extra protection against road shocks while boosting the springs’ load capacity. The result is a kit that resists leaks, rust, and wear so you can count on it season after season.
Installing real suspension support doesn’t have to be complicated. The LoadLifter 5000 comes with all necessary brackets, hardware, air lines, and manual valves for a complete install. Mount the springs, route the airlines, and use the included valves—typically mounted on the bumper—for easy access to air adjustments. Add an optional compressor system later if you want automated pressure control. It’s a clean setup built with the do-it-yourself installer in mind.
