- Brand: ARP

- Country of Manufacture: United States
ARP Pro Series head studs are engineered for maximum performance and reliability, making them the top choice for professional engine builders. Manufactured from premium grade 8740 alloy and proprietary ARP2000 alloy, these studs offer superior strength compared to standard “aircraft” quality steels. Each stud undergoes precise vertical heat treatment—190,000 psi for 8740 material and 220,000 psi for ARP2000 material—ensuring complete heat penetration and consistent quality.
Exacting manufacturing tolerances guarantee perfect alignment of gaskets and cylinder heads, simplifying assembly and servicing, particularly in high-performance and racing engines. Studs provide more accurate and consistent torque loading compared to bolts, as they are installed hand-tight and only experience vertical stretch under load, resulting in even clamping force across the cylinder head.
ARP controls all aspects of the manufacturing process to ensure optimal quality and reliability, making these head studs a dependable choice for demanding applications.
