ARP (Automotive Racing Products) makes the strongest fasteners in motorsport — head studs, main studs, rod bolts, and flexplate bolts used by every Formula 1, NHRA, NASCAR, and championship motorsport program. Aerospace-grade alloys, exact-fit machining.
Achieving a reliable head gasket seal is the most critical step in any Gen III Hemi build. The Auto Racing Products (ARP) Pro Series Cylinder Head Bolt Kit (147-3901) provides the necessary clamping force to handle increased cylinder pressures, whether you are running a naturally aspirated setup or forced induction. Designed specifically for the 5.7L and 6.1L Hemi platforms, these bolts are a direct upgrade over stock hardware.
These bolts are manufactured from high-strength chromoly steel and heat-treated to ensure they maintain their integrity under extreme thermal cycling. The 12-point head design allows for precise torque application, ensuring that your cylinder heads are seated evenly across the entire surface. By utilizing these professional-grade fasteners, you eliminate the risk of head gasket failure caused by bolt stretch. Upgrade your Hemi build with the best hardware on the market.
