Designed for durability and performance, the ALPHA HD PRO™ Series comes with jounce bumpers/bump stops — a flexible polyurethane bumper inside the bag that prevents bottoming out, protecting the air springs from damage. This design also allows the system to operate 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 needing maximum bag travel and stability while offroading, towing, launching boats, or lowering the rear to pick up trailers, the ALPHA HD air bag system provides strong load-leveling capability up to 5,000 lbs.
