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.
Enhance the reliability of your Porsche 2.5L SOHC or DOHC engine with the Auto Racing Products (ARP) Cylinder Head Stud Kit. Specifically designed for high-performance applications, these undercut studs provide the clamping force necessary to keep your cylinder head sealed under high-compression and high-RPM conditions.
The undercut design of these studs is critical for distributing stress evenly, which significantly reduces the risk of stud failure and head gasket leaks. Manufactured from high-tensile chromoly steel, these studs are far superior to factory head bolts. The 12-point nuts ensure easy installation and provide a secure, reliable connection that holds up under the rigorous demands of racing or spirited street driving. This kit is an essential component for any engine rebuild, providing the peace of mind that your engine will stay sealed regardless of the power output. Trust in the proven performance of ARP hardware for your Porsche engine build. Explore our complete selection of performance engine fasteners at GGCRACING.
