When heavy loads or trailers push down the rear of your vehicle, steering and braking can get sketchy. The Air Lift 1000 Universal Air Spring Kit adds up to 1,000 lbs of load-leveling support inside your rear coil springs, keeping your ride level and predictable under load. With the suspension back in its proper range, your handling, braking, and headlight aim stay steady no matter what you’re hauling.

Every load is different, and this system lets you dial in support for each one. You can manually adjust the air pressure anywhere from 5 psi up to 35 psi when spring pitch is greater than 1", or up to 50 psi when it’s less than 1". Inflate or deflate the polyurethane air springs as needed using built-in Schrader valves for even weight distribution and a smoother ride. Add a compressor system (sold separately) if you want on-demand adjustments from the driver’s seat.

Bumpy roads and uneven loads can make your vehicle bounce and sway. These tough polyurethane air springs sit inside your coil springs to absorb road shocks and reduce sway. The result is a more stable, comfortable ride whether you’re towing a camper, hauling tools, or driving home empty after a long day.
A good suspension helper should last through years of use. The Air Lift 1000’s polyurethane construction resists wear and tear while protecting your factory suspension from extra strain. With proper setup, these air springs keep your vehicle riding level, improve tire wear, and cut down on suspension stress mile after mile.
