Designed for extreme durability and performance, the ALPHA HD PRO S™ Series comes with stainless steel hardware and integrated jounce bumpers/bump stops. The flexible polyurethane bumper inside the air spring prevents bottoming out, protecting the springs from damage, and allows the system to operate at 0 psi when unloaded for factory ride comfort.
This system is perfect for users who want peace of mind from having an internal bumper and improved ride comfort whether towing or not towing. For those seeking maximum bag travel and enhanced control when off-roading, towing, launching boats, or lowering the rear to hook up trailers, the ALPHA HD air bag provides dependable load-leveling performance with up to 5,000 lbs of capacity.
