It's a proven fact that factory head bolts are the weak link in a diesel engine; especially if the engine has been modified. That's because Ford® Power Stroke® engines are assembled using "Torque to Yield" (TTY) bolts and preloaded to yield and beyond (typically 100-110%). Any increases in combustion pressure can lead to problems like blown head gaskets or catastrophic engine failure. And because TTY bolts are yielded by design, they should never be re-used.

ARP solves the problem by offering head studs that are designed for higher clamping loads. They are available in several different strength materials to safely handle applications from performance street to all-out competition use.

Similiar improvemnts over factory TTY bolts are provided by high strength ARP main studs.

And there's more. With increased performance you need the extra security that ARP flywheel and flexplate bolts can provide.

Features:

  • Constructed of Premium grade 8740 alloy and a proprietary ARP2000® alloy that are rated far superior to "aircraft" grade alloy steels.
  • Each stud is placed vertically into special racks and precisely heat-treated to to ensure complete heat penetration.
  • Each stud is centerless ground to make it as close to perfectly concentric as possible.
  • ARP studs are thread rolled after heat-treat, which gives them about (20x) better fatigue strength than studs that re threaded prior to heat-treat
  • Undercut studs to equalize the "stretch" of the studs, resulting in more consistent clamping force - and one that compensates for head gasket compression once cylinder heads are installed preventing blown head gaskets and assure optimum sealing
