Heavy loads can make the back end sag, throwing off steering, braking, and headlight aim. The Air Lift 1000 system adds up to 1,000 lbs of load-leveling support to your rear coil spring suspension so the vehicle stays level under cargo or trailer weight. This keeps handling predictable, braking even, and ride height steady for safer travel whether you’re hauling gear or towing a full load.
Every load is different, and these molded polyurethane air springs let you dial in support for each one. Inflate or deflate manually between 5 psi and 35 psi to match your setup—firm when loaded, soft when running light. With dual air lines installed, you can even inflate each spring independently to level off-center loads and fine-tune balance side to side.
Road dips and cornering forces can make a fully loaded vehicle bounce or sway. These air springs fit neatly inside the existing rear coils to absorb road shock and cut down on body roll. The added cushion improves ride quality while reducing strain on tires and factory suspension components, keeping everything planted through turns and over uneven pavement.
This system installs inside your rear coil spring suspension using standard tools. The kit includes two air springs, heat shields, tubing, Schrader valves, and all necessary hardware. Manual inflation valves are typically mounted on the bumper for easy access, and optional compressor systems can be added later for in-cab pressure control. With simple routing and clear instructions, setup is direct enough for a weekend driveway install.

Yes, I did the air lines over sealing each joint and I have not had air deflation since. I am now very satisfied with this product. I have towed over 20,000 miles and have had no problem.
