E-Series Head Bolt Kit BBM 440

The E-Series Head Bolt Kit BBM 440 is a precision fastener assembly designed for high-performance cylinder head applications on Mopar B and RB-Series engines. This kit provides operators and engine builders with OEM-grade fasteners that maintain critical clamp load and head gasket sealing integrity under extreme combustion pressures and thermal cycling.

Manufactured from chromoly steel and finished in black oxide, the E-Series Head Bolt Kit BBM 440 delivers superior tensile strength and corrosion resistance compared to standard zinc-plated fasteners. The hex head design allows for precise torque application using conventional socket tools, ensuring accurate preload distribution across all cylinder head mounting points. The black oxide coating protects against rust while reducing reflectivity.

Engine builders, restoration specialists, and performance technicians benefit most from this kit's consistency and durability. While it is compatible with Mopar B and RB-Series engine blocks, it is important to verify compatibility with specific cylinder heads before use.
