Product Description
ARP 250-4301 Head Stud Kit – 2011–2016 Ford 6.7L Powerstroke
Lock down your 6.7L with the ARP 250-4301 Head Stud Kit—built from ARP2000 material and engineered for extreme cylinder pressures common to tuned/towed Powerstroke trucks. This kit delivers the clamping force and repeatable torque you need to help prevent head-gasket lift while supporting reliable power. Includes studs, 12-point nuts, and hardened parallel washers for even load distribution and accurate torque readings.
Pair these head studs with other ARP fasteners for a bulletproof 6.7L build: ARP 250-5802 Main Stud Kit, ARP 150-2801 Flywheel Bolt Kit, ARP 150-2901 Flexplate Bolt Kit, and ARP 150-2504 Harmonic Balancer Bolt Kit.

FAQs
Q: Will ARP 250-4301 help prevent head-gasket failures on tuned 6.7L trucks?
A: Yes—these ARP2000 studs provide significantly more clamping force and stability than factory bolts, which helps resist head lift under high cylinder pressures.
Q: Do I need to machine the heads or block?
A: No special machining is required for installing studs themselves; however, any head-gasket job benefits from proper surface prep and inspection.
Q: What torque specs should I use?
A: Use the torque values and sequence from ARP’s official instructions for kit 250-4301.
Q: Can I reuse ARP studs?
A: Studs are generally reusable if they pass inspection and are not yielded or damaged. Always follow ARP guidance.
