Pacbrake ALPHA XD PRO STM Air Bags / Air Helper Springs
Eliminate truck sag, sway, and bottoming out with Pacbrake ALPHA XD PRO STM air bags. Built for extreme-duty performance, these air helper springs feature inch-thick corrosion-resistant end caps and 20 internal support wires—delivering maximum strength and long-term durability.
Designed for durability and performance, the ALPHA XD PRO STM Series includes stainless steel hardware and integrated jounce bumpers (bump stops). These flexible polyurethane bumpers inside each air spring prevent bottoming out and protect against damage under heavy load conditions.
A major advantage of this system is the ability to run the air bags at 0 PSI when unloaded, maintaining factory ride comfort when not towing or hauling. This makes it ideal for drivers who want maximum load support while keeping everyday drivability.
For applications requiring maximum air bag travel—such as off-roading, towing, launching boats, or frequent trailer hookups—consider the Pacbrake HP10677-X ALPHA XD air bag option.
Performance:
*Never exceed the manufacturer’s recommended Gross Vehicle Weight Rating (GVWR).
Kit Includes:
