Billet Timing Set - BBM 3-Bolt

The Billet Timing Set – BBM 3-Bolt by COMP CAMS is designed for engine builders and performance mechanics who require precision and reliability in ignition timing control. This hardened billet component replaces the factory OEM timing gear assembly, addressing issues of deflection and inconsistency that can occur in stock setups, particularly in high-RPM and boosted applications.

Constructed from billet aluminum, this timing set features a robust 3-bolt mounting design that minimizes timing drift under load and vibration. Unlike cast iron OEM gears that can wear over time, the billet construction helps maintain tight tolerances, ensuring that cam timing remains accurate. The 3-bolt configuration offers superior clamping force, which is essential for consistent ignition mapping across various engine management systems.

This timing set is particularly beneficial for those upgrading their small-block or mid-size domestic engines with performance cam modifications. Installation requires basic mechanical skills and follows standard timing gear removal procedures, making it accessible for both DIY enthusiasts and professional mechanics.
