Bolt & Divider Kit - for 1621 BBM B/RB

The Bolt & Divider Kit - for 1621 BBM B/RB from COMP Cams is an essential component for engine builders and performance mechanics working specifically with the Chrysler 1621 BBM B/RB block. This fastener and divider assembly kit addresses a critical need in high-performance small-block and big-block combinations where precision rocker geometry and valve train integrity are paramount. Whether you're assembling a vintage muscle car engine, rebuilding a performance street machine, or constructing a dedicated race platform, this kit ensures proper alignment and secure retention of core valve train components.

COMP Cams engineered this bolt and divider kit to maintain consistent rocker arm positioning and prevent lateral movement during high-RPM operation. The divider component isolates valve actuation zones and reduces cross-firing interference between adjacent cylinder banks, a common issue in aggressive cam profiles and forced-induction applications. Manufactured to exacting tolerances, the kit's fastener design accommodates the specific bolt patterns and thread specifications of the 1621 BBM cylinder head configuration, ensuring repeatable installation and long-term reliability under sustained engine load.

This compact assembly (2.8 x 2 x 4 inches, weighing 1.7 pounds) integrates seamlessly into tight underhood environments without compromising accessibility. This kit is indispensable for engine shops, performance builders, and hands-on enthusiasts who demand factory-grade engineering and reliability in their builds. With its precise design and robust construction, the Bolt & Divider Kit is a must-have for anyone working on the Chrysler 1621 BBM B/RB block.
