Need extra durability and performance in your air suspension? PacBrake is proud to to offer the newest upgrade to their line of Alpha Air, Alpha HS Pro S Air Suspension Kit. Created to offer maximum toughness and performance, the Alpha HD Pro S is built with stainless steel hardware, Jounce Bumpers/Bump Stops (a flexible polyurethane bumper inside the bag that prevents bottoming out, which could damage your air springs), and allows you to run your bags at 0 psi when unloaded for factory ride comfort. What this means is that your air system can take a break when your not towing so you aren't wearing it out when you don't need to. On top of this, you have the amazing ride comfort you always get from PacBrake.

The Alpha HD Pro Series is designed to offer both durability and performance. The Jounce Bumpers/Bump Stops are flexible polyurethane bumpers inside the bag that prevent bottoming out, which could damage your air springs. You can also run your bags at 0 psi when unloaded for factory ride comfort. This feature is perfect for those who want the peace of mind of having an internal bumper and covet the ride comfort of being able to run without air when not towing.
