2020-2026 Duramax Alpha HD Pro Air Suspension Kit W/ 5th Wheel Prep (HP10725-J)

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

The ALPHA HD PRO pairs Pacbrake's HD air springs with internal jounce bumpers. The polyurethane bump stop sits inside the bag, so the spring cannot bottom out and damage itself, and you can run the kit at 0 psi when the truck is empty for a factory feel ride.

Air up when the load goes on and you get up to 5,000 lbs of load leveling capacity, so the truck sits level, tracks straight and stops squatting and bouncing under the weight.
