Pacbrake Hp10387-X Helper Spring Kit

Eliminate truck sag, sway and bottoming out with ALPHA XD air bags/ air helper springs, the only brand with inch-thick corrosion resistant end caps and 20 support wires for maximum strength and durability. Do not risk the air leaks and cold weather fractures that are more common in the plastic end caps that can happen with competitor air springs. When hauling heavy loads, the rear springs can be pushed to the limit - resulting in excessive bounce, sagging ride height, and an overall feeling of instability. And, if you are hauling these massive loads on regular basis your truck needs some extreme duty air springs to level that load. With the simple addition of an Alpha XD 7500 Pound Air Spring Suspension Kit you can distribute weight evenly to your tires, supporting any load without overtaxing your existing system.The big 7-inch double convoluted bellow type air springs have increased volume for that added load-leveling capacity.
