Description
When only the best will do, ARP Pro Series cylinder head studs are the go-to choice for professional engine builders and performance enthusiasts alike. Manufactured from premium 8740 alloy and cold-forged for superior molecular integrity, these studs are heat-treated to 200,000 psi to handle extreme cylinder pressures. Thread rolled after heat treatment, ARP’s studs deliver unmatched fatigue strength and reliability—making them the ideal solution for engines pushed to their limits.
Every ARP Pro Series kit includes precision-machined 12-point nuts and hardened parallel-ground washers to ensure even clamping loads and accurate torque readings. The studs are centerless ground for perfect concentricity, allowing head gaskets and cylinder heads to glide smoothly into place with flawless alignment. Designed to deliver consistent performance under the harshest conditions, ARP studs are a must-have upgrade for serious builds where failure is not an option.
