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 air springs from damage.
This design allows you to run the bags at 0 psi when unloaded for factory ride comfort. With up to 5,000 lbs of load leveling capacity, it provides a smoother, more stable ride for towing, off-roading, hauling, and frequent heavy-load use.
