Designed for durability and performance, the ALPHA XD PRO™ Series comes with jounce bumpers/bump stops — a flexible polyurethane bumper inside the air spring that prevents bottoming out, protecting the bag from damage. This design also allows the system to run at 0 psi when unloaded, providing factory ride comfort. It is ideal for users who want the peace of mind of internal bumper protection whether towing or not towing.
For those who require maximum bag travel and enhanced control when off-roading, towing, launching boats, or lowering the rear to hook up trailers, the ALPHA XD air spring system offers strong load-leveling performance with a 7,500 lb capacity.
