BBM Main Bolt Kit - Fits 426 Hemi 2-Bolt

The ARP BBM Main Bolt Kit for the 426 Hemi 2-bolt configuration is designed for high-performance engine builders and serious engine work that requires OEM-spec reliability with enhanced material properties. This main bolt kit serves as a drop-in replacement for factory fasteners in Mopar 426 Hemi applications, ensuring consistent clamping force and fatigue resistance under extreme power levels.

Manufactured from premium chromoly steel with a black oxide finish, the BBM Main Bolt Kit offers superior tensile strength and corrosion resistance compared to stock fasteners. The cross-bolt design distributes clamping loads evenly across the main bearing saddle, reducing stress concentration and preventing main cap walk—a critical failure point in high-RPM or high-boost applications. The black oxide coating protects against oxidation while maintaining consistent friction characteristics during installation.

Engine builders, race teams, and restoration specialists rely on this main bolt kit when uncompromising fastener quality is essential. This kit is specifically tailored for the 426 Hemi 2-bolt configuration, making it the ideal solution for both stock-appearing builds and high-performance applications.
