Heavy trailers, campers, and bed loads can make even a solid truck squat in the rear. The Air Lift LoadLifter 5000 Ultimate air springs add up to 5,000 lbs of load-leveling capacity to keep your stance even. With adjustable air pressure from 5 to 100 psi, you can raise or soften the support to match the load. Leveling out your ride keeps steering sharp, braking balanced, and headlights aimed where they belong—especially when towing or hauling uneven cargo.
These air springs include internal urethane jounce bumpers that smooth out rough roads and act as a built-in backup if air pressure ever drops. The hybrid design combines the tunable feel of air springs with the reliability of jounce-style springs. The jounces engage progressively—the more weight you add, the stiffer they get—so bumps and dips don’t bottom out the suspension. Even at lower pressures, you get a more comfortable, controlled ride when empty or loaded.
The LoadLifter 5000 Ultimate is made with 2-ply, fabric-reinforced rubber air bags protected by exclusive upper and lower roll plates that guard against damage from moving parts underneath. High-strength Zytel nylon endcaps are lighter than steel but resist rust and corrosion better. The urethane jounce inserts require no maintenance and handle hot or cold conditions without breaking down, giving you reliable support for years of towing and hauling.
Installing these springs doesn’t require a shop full of tools. The kit includes mounting brackets, hardware, manual inflation valves, and air lines for both sides. Once bolted on, you can route the inflation valves to your bumper for quick access or add an optional compressor system for in-cab control. Just mount the springs, air them up, and you’re ready to haul with a level stance and steady handling every time.

The air fittings on the air bags leak, I changed them out but I think after time they will leak again. But the unit works great I would recommend
