ARP (Automotive Racing Products) makes the strongest fasteners in motorsport — head studs, main studs, rod bolts, and flexplate bolts used by every Formula 1, NHRA, NASCAR, and championship motorsport program. Aerospace-grade alloys, exact-fit machining.
When pushing your Subaru EJ-Series SOHC engine to the limit, stock head bolts often fail to maintain the necessary clamping force. The Auto Racing Products (ARP) 12pt Head Stud Kit is engineered to provide the structural integrity required for high-performance and boosted applications. Manufactured from premium 8740 chromoly steel and finished with a durable black oxide coating, these studs are designed to prevent head gasket failure under extreme cylinder pressures.
The 12-point design allows for easier access in tight engine bays, ensuring you can achieve precise torque specs without clearance issues. By upgrading to this professional-grade fastener kit, you ensure that your cylinder head remains perfectly seated, regardless of boost levels or compression ratios. Whether you are building a street-strip warrior or a dedicated track car, these studs provide the peace of mind that your engine internals are locked down tight. Invest in the best engine hardware available at GGCRACING.
