Description

Note: This is the 5th wheel version. It fits trucks with (OEM) 5th wheel prep packages, where the standard HP10585 kit does not.

Hauling a fifth wheel and tired of watching the back of the truck squat every time you hitch up? Pacbrake's ALPHA HD air springs put the ride height back where it belongs and keep it there, loaded or empty.

Up to 5,000 lbs of load leveling capacity spreads the weight evenly across the tires instead of overtaxing the factory leaf packs, so you get a level stance, better control and none of the sag, sway or bottoming out.

Part Number: HP10725
