About ARP

ARP (Automotive Racing Products) was founded in 1968 and is based in Ventura, California. ARP builds high-strength engine fasteners for racing and performance use. In the diesel world the name usually means one thing: head studs. ARP head stud kits for Duramax and Cummins are the usual fix for a lifted head on a truck making more boost than the factory bolts were built for.

What we carry

We stock the ARP hardware a Duramax or Cummins needs before it sees more boost or bigger injectors. Head studs are first on that list.

  • Head stud kits for 2001-2016 Duramax, 2017-2025 Duramax and 1998.5-2024 Cummins, in a standard kit or a Custom Age 625+ kit
  • Balancer bolt kit and harmonic balancer washer for 2001-2023 Duramax
  • Valve cover bolt kits for 2004.5-2016 Duramax, in black oxide or stainless steel
  • Chromoly bolts, M10 x 1.50 x 30, for 2001-2016 Duramax
