ARP 250-4301 Ford 6.7L Powerstroke Diesel Head Stud Kit

The ARP 250-4301 head stud kit is engineered specifically for Ford 6.7L Powerstroke diesel engines, providing superior clamping force and reliability for high-performance and heavy-duty applications. These premium head studs are manufactured from ARP's proprietary 8740 chromoly steel material and heat-treated to deliver exceptional tensile strength of 200,000 PSI, far exceeding OEM fastener specifications.

Key Features:

• Precision-manufactured from 8740 chromoly steel with 200,000 PSI tensile strength
• Thread-rolled design for superior fatigue resistance and strength
• Parallel ground washers ensure even load distribution across the cylinder head
• Black oxide coating for corrosion resistance
• Includes premium-grade ARP Ultra-Torque fastener assembly lubricant
• Essential upgrade for boosted, modified, or high-mileage Powerstroke engines
• Allows for precise and repeatable torque values during installation

ARP head studs are the proven choice for diesel performance enthusiasts and professional engine builders who demand maximum reliability under extreme cylinder pressures. Unlike factory TTY (torque-to-yield) bolts that cannot be reused, ARP studs provide consistent clamping force and can be removed and reinstalled multiple times without compromising integrity. This kit includes all necessary studs, washers, and assembly lubricant for a complete cylinder head installation on 2011-2023 Ford 6.7L Powerstroke diesel engines.
