ARP Head Stud Kits | Multiple Ford Fitments (155-3604)

The ARP Head Stud Kit from ARP is a high-performance fastener set designed for demanding engine applications. Constructed from chromoly steel and finished with a black oxide coating, these head studs provide exceptional strength, rated at 180,000 psi—15 percent stronger than Grade 8 fasteners. The kit features either a reduced wrenching hex head or a 12-point head, facilitating easier installation and re-torqueing without the need to remove valvetrain components. These studs are engineered to deliver reliable clamping force and durability under high-stress conditions, making them ideal for performance and racing engines.

Designed for a variety of Ford applications, these ARP head studs are compatible with multiple Ford models and engine configurations. They serve as a direct upgrade or replacement for stock fasteners, ensuring improved head gasket sealing and overall engine integrity. Suitable for street, track, or high-performance builds, these bolt sets are intended for use in engines requiring enhanced fastener strength. Installation involves replacing existing head bolts with these studs, which do not include washers but provide a secure, long-lasting fit for demanding automotive environments.
