Product Description
ARP 134-3610 High Performance Head Bolt Kit for 2005+ LS Engines
Premium 8740 Chrome Moly Head Bolts for Gen IV LS Applications
The ARP 134-3610 High Performance Head Bolt Kit is engineered to deliver superior clamping force, durability, and reliability for 2005 and newer GM LS engines. Manufactured from premium 8740 chrome moly steel and heat treated to 190,000 PSI, these head bolts offer a significant strength upgrade over factory fasteners. ARP’s thread-rolling process performed after heat treatment dramatically improves fatigue resistance, ensuring long-term sealing integrity in both stock and high-performance LS engine builds.
