2020-2026 Duramax Alpha XD 7500 Air Suspension Kit W/ 5th Wheel Prep (HP10725-X)

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

The ALPHA XD is Pacbrake's heavy end of the range. Big 7 inch double convoluted bellows hold far more air than a standard sleeve spring, which is what gets you to 7,500 lbs of load leveling capacity instead of 5,000. If your Duramax works hard for a living and the standard ALPHA HD is not enough spring, this is the kit.

One piece aluminum end caps and 20 support wires mean no cracked plastic caps in a Canadian winter and no slow leaks a year down the road.
