Designed for durability and performance, the ALPHA XD PRO™ Series comes with bump stops and stainless steel hardware. The flexible polyurethane bumper inside the air spring prevents bottoming out, which could damage the springs, and allows operation at 0 psi when unloaded for factory ride comfort. It is ideal for users who want peace of mind from having an internal bumper and smooth ride performance whether towing or not towing.
For those who desire maximum bag travel, especially when off-roading, towing, launching boats, or lowering the rear to pick up trailers, the ALPHA XD air bag system provides increased stability and control with a 7,500 lb load leveling capacity.
