Fits 2003-Newer Hemi Engines 5.7L 6.1L 6.2L 6.4L
The ARP 147-3901 Pro Series Head Bolt Kit is engineered to deliver superior clamping force, durability, and reliability for 2003-newer Chrysler Hemi V8 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.
