Designed for durability and performance, the ALPHA HD PRO™ Series comes with jounce bumpers/bump stops — flexible polyurethane bumpers inside the air springs that prevent bottoming out and protect the system from damage. This design allows you to run the bags at 0 psi when unloaded for factory ride comfort.
It is perfect for users who want peace of mind from having an internal bumper whether towing or not towing. For those who need maximum bag travel for offroading, towing, boat launching, or lowering the rear for trailer hookup, the ALPHA HD air bag system delivers reliable performance with up to 5,000 lbs of load-leveling capacity.
