Enhance your vehicle's performance and safety with ALPHA XD 7500 lb air bags/air helper springs from Pacbrake, designed to eliminate truck sag, sway, and bottoming out.

With Pacbrake's extreme-duty air springs, you can distribute weight evenly across your tires, preventing overtaxing of your suspension system. These springs are engineered for maximum strength and durability, featuring one-piece aluminum end caps and 20 support wires—a design that minimizes the risk of air leaks and cold weather fractures often associated with plastic end caps.

Rated for up to 7500 lbs. of load-leveling capacity, ALPHA XD 7500 air springs are perfect for those who regularly tow or haul heavy loads. These springs feature a robust 7-inch double convoluted bellow type design, ensuring your truck maintains a level stance while providing additional support for a smooth and safe ride.
