Fits LSA Engines ONLY: 2009-2015 CTS-V, 2012-2015 ZL1 Camaro
The ARP 134-3613 High Performance Head Bolt Kit is engineered to deliver superior clamping force, durability, and reliability for GM Supercharded LSA 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.
