Eliminate truck sag, sway, and the risks of bottoming out with ALPHA HD Pro™ air bags / air helper springs from Pacbrake, distinguished by their inch-thick, corrosion-resistant end caps and reinforced with 20 support wires for unparalleled strength and durability.

The ALPHA HD PRO™ Series is meticulously designed for durability and performance, integrating Jounce Bumpers/Bump Stops. These innovative, flexible polyurethane bumpers nestled inside the air bags are a safeguard against bottoming out, protecting your air springs from potential damage. Uniquely, they enable the operation of your bags at 0 psi when not loaded, preserving factory ride comfort seamlessly. It's an ideal solution for those who not only seek the security of an internal bumper but also cherish the ability to maintain a ride without air when not engaged in towing activities. For enthusiasts who prioritize maximum air bag travel, vital for off-roading, towing, launching boats, or those regularly needing to adjust their vehicle's rear height for trailer connectivity, our HP10355 ALPHA HD air bag emerges as the ultimate choice. With a load leveling capacity reaching up to 5,000 lbs*, it ensures your vehicle's balance and control, regardless of the task at hand. Always remember, adhering to the manufacturer's recommended Gross Vehicle Weight Rating is crucial for safety and optimal functionality.
