PacBrake HP10725-J ALPHA HD PRO Air Bags w/ Bump Stops, Silverado/Sierra 2500HD/3500HD (20-26)

Eliminate truck sag, sway and bottoming out with ALPHA HD PRO™ air bags (air helper springs) from Pacbrake. Pacbrake is the only brand with inch-thick, corrosion resistant end caps and 20 support wires for maximum strength and durability.

The ALPHA HD PRO Series adds jounce bumpers (bump stops): a flexible polyurethane bumper inside each bag that prevents bottoming out, which could damage the air springs, and lets you run the bags at 0 psi when unloaded for factory ride comfort. It is the pick for anyone who wants the peace of mind of an internal bumper and the ride of running without air when not towing.
