The ARP 250-4301 Diesel Head Stud Kit is a must have upgrade for your 2011-2016 Ford 6.7L Powerstroke. These extra heavy duty studs are rated at 220,000 psi tensile strength and provide the clamping force required to keep your 6.7L Powerstroke’s cylinder heads from lifting due to higher combustion pressures.
The ARP Head Studs are manufactured in ARP’s 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.
