The ARP 250-4301 Ford 6.7L Diesel Head Stud Kit is a must have upgrade for your 2011-2023 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.
If you've done even mild upgrades to your 6.7L Powerstroke, we recommend replacing your stock head bolts with head studs as solid preventative maintenance. These trucks are almost too easy to add exponential power to, meaning cylinder pressures can increase if other factors are not addressed, especially if you have a lead foot. The best means to prevent against head gasket(s) failure is by upgrading to a set of ARP's 220,000 PSI Tensile Strength Head Studs. This kit comes complete, ready to install including heat-treated, chromoly steel 12-point nuts and washers.
