Heavy loads can make the rear sag and throw off how your vehicle drives. The Air Lift 1000 kit adds up to 1,000 lbs of load-leveling support right inside the rear coil springs. By taking some of the strain off the factory suspension, it keeps ride height level so steering, braking, and headlight aim stay where they should. You’ll feel the difference in handling confidence every time you hitch up or haul a full load.
Every job is different, and that’s where this system shines. Each air spring can be inflated from 5 psi to 35 psi to match your load. Keep minimum pressure when driving empty for a smooth ride, then bump it up when towing or hauling to keep things level. With dual air lines installed, you can even adjust each side independently to balance uneven loads.
Hauling weight over bumps and dips can make the rear bounce, sway, or squat. These molded polyurethane air springs work with your existing suspension to absorb road shock and reduce sway. The result is a steadier feel through corners and less bounce over uneven pavement so you stay comfortable and in control no matter what’s behind you.
Designed to slip right inside your rear coil springs, the Air Lift 1000 kit installs with standard tools and comes with tubing, Schrader valves, heat shields, and hardware. Once in place, it supports heavy loads without changing everyday ride quality. Add a compressor system later if you want on-the-fly air pressure adjustment—either way, you’re set up with reliable load support that’s easy to maintain for the long haul.

I have towed my RV several times over the last year and these helper springs work perfectly! I had a very small air leak but I added some silicone at the airline connections and it is 100 percent! I carry a battery powered air compressor with me and it’s basically a “set it and forget it” systems.

Yes! Soapy water is a great piece of advice! I'd still like to know what you think once you have had a chance to try them out, too :)

Great improvement to my ride height when towing my 22 foot toy hauler. Really help stabilize the rear of the H2 Hummer.

The helpers look great on your Hummer, Rob! What kind of travel trailer are you hauling?
