Heavy towing or hauling can leave your truck squatting low in the rear. The LoadLifter 7500 XL Ultimate air springs add up to 7,500 lbs of load-leveling support to keep your ride level and steady. The 7" diameter double-bellows springs have more air volume than smaller systems, giving you greater leveling strength at lower pressures. With your suspension properly supported, steering and braking stay firm, headlights stay aimed right, and tires wear evenly mile after mile.
Even when the bags run low on air, the built-in jounce bumper inside each spring protects your suspension from harsh bottoming out. It cushions heavy hits when driving with an underinflated or uninflated bag. Air Lift’s exclusive roll plates on top and bottom add extra protection and increase load capacity while reducing wear on the rubber. The result is a smoother ride that absorbs road shock instead of transferring it through the frame.
Every load is different, and these bags let you fine-tune your setup for each one. You can inflate each spring independently to balance off-center loads or adjust both together for even support front to back. The included manual inflation valves mount for easy access—usually on the bumper—and make adjusting simple with any air source. Add a compressor system later if you want in-cab control or automatic adjustment.
Each air spring is constructed from 2-ply, fabric-reinforced rubber with high-strength Zytel nylon endcaps that are lighter, stronger, and more corrosion resistant than steel. All mounting brackets, hardware, and air lines are included for a solid installation. Once set up, you’ve got heavy-duty suspension support designed to reduce strain on your factory components and maintain stable handling under the heaviest loads.

After 1 yr of use hauling 6-8 ton of hay smooth ride, not showing any signs of air leaks, not showing any wear or deterioration on any of the components.

One year later and my Air LoadLifter 7500XL is working great! Towing our 40ft. 5th wheel with 4 slides is much smoother now. We found 35 to 40 psi works best while towing it. I run different psi when towing my excavator. It is great to be able to adjust the psi according to the weight and position of the load on my trailer.

No issues with the air bag system. It has kept the truck level when hauling the 5th wheel. Well worth the money to install the system and have the smooth level ride.

Air Lift continues to be a valuable tool in managing towing heavy loads. I adjust the pressure depending on the weight and distribution of the load on my 30 ft gooseneck trailer. Users should be aware that if the pressure is set in the morning when it is cool, the pressure may increase 10 or 20 psi as the surrounding temperatures increase into the afternoon. Great product!

This system has been on my 2018 Ram 3500 SRW. We tow a horse trailer and use it everyday. I installed it myself. Works perfectly. We are now going to put one on the 2007 Ram 2500
