Resolve issues of truck sag, sway, and the risk of bottoming out with the ALPHA HD PRO™ air bags / air helper springs from Pacbrake. Stand out with the robustness offered by inch-thick corrosion-resistant end caps and 20 support wires, ensuring the utmost strength and longevity.

The ALPHA HD PRO™ Series is engineered with durability and performance at its core, featuring Jounce Bumpers/Bump Stops. These flexible polyurethane bumpers, nestled inside the air bags, are designed to prevent the damaging effect of bottoming out and enable operation at 0 psi when unloaded, maintaining the original ride comfort of your vehicle.

Ideal for those seeking the assurance of an internal bumper for protection and who value the ability to enjoy a comfortable ride without air pressure when not engaged in towing activities.
