Bellhousing Bolt Kit 6pt SBM 273-360

The Bellhousing Bolt Kit 6pt SBM 273-360 is engineered for Mopar small-block engine builders and enthusiasts who demand reliability where engine and transmission meet. This critical fastening system secures the bellhousing to your Mopar 273, 318, or 360 cubic-inch engine block, preventing the catastrophic separation that can occur under boost, high RPM load, or extreme acceleration. Whether you're building a street machine, drag car, or performance restoration, proper bellhousing fastening is non-negotiable for safety and durability.

ARP (Applied Reliable Products) specializes in fasteners engineered for high-stress applications, and this kit features premium-grade bolts with 6-point heads that resist rounding compared to 12-point alternatives. The SBM designation confirms these are sized and specified for small-block Mopar applications, delivering consistent clamping force that maintains concentricity between engine and transmission. The compact kit weighs just 0.54 pounds, making it ideal for weight-conscious builds while maintaining the structural integrity essential for forced-induction or high-RPM applications.

Installation is straightforward for those familiar with engine assembly: remove original fasteners, apply a light coat of ARP Ultra-Torque or equivalent assembly lubricant, and install using a calibrated torque wrench to specification. This kit is essential if you're upgrading from stock fasteners to a performance transmission, installing a modern overdrive unit, or rebuilding an engine after a prior failure. Mopar drag racers, street rod builders, and restoration shops rely on ARP bellhousing bolts to ensure repeatable, fail-safe assembly that survives repeated heat cycles and extreme loads.
