ARP Head Studs - 6.7 Powerstroke 2011-2016

ARP 250-4301 Head Stud Kit

These extra heavy ARP studs are rated at 220,000 psi tensile strength and provide the clamping force required to keep your 6.7L Powerstrokes cylinder heads from lifting due to higher combustion pressures. Adding head studs can ensure you keep them in place without gasket failures during performance modifications. ARP Fasteners are the premier head stud manufacturers for all diesel performance applications. Each stud is a direct replacement for the factory head bolts that comes in the 6.7L engine.

The ARP Head Studs are manufactured in ARPs Santa Paula, CA plant from proprietary ARP 2000 material, with threads rolled after heat-treating to provide optimum fatigue strength. They are center-less ground to assure perfect concentricity. Also included in each kit are heat-treated, chrome-moly steel 12-point nuts and parallel-ground washers, with a black oxide finish for extra durability.
