BBM Timing Tab - Black

The BBM Timing Tab - Black is a precision timing indicator designed for engine builders and mechanics who demand accuracy during initial startup and tuning operations. This compact tool serves a critical function in the ignition timing workflow, allowing you to verify proper ignition advance without reliance on electronic diagnostics alone. Whether you're dialing in a fresh engine build, tuning a carbureted platform, or validating distributor settings on a classic muscle car, the timing tab provides the mechanical reference point that separates guesswork from confidence.

The BBM Timing Tab mounts directly to the harmonic balancer or crankshaft pulley, creating a fixed pointer datum against which you can observe the balancer's degree markings under a timing light. The black finish ensures high contrast visibility when directing a strobe toward the balancer during engine idle and load conditions. At just 0.17 lbs with compact dimensions of 5.9 x 1.4 x 9.7 inches, the tab adds negligible mass and installs without requiring crankshaft removal or significant teardown.

This timing tab proves indispensable for street engine tuning, performance dyno work, and engine assembly shops where repeatability and documentation matter. Enthusiasts rebuilding big-block and small-block engines will find this tool particularly useful for ensuring accurate ignition timing. Its straightforward installation and reliable performance make it a valuable addition to any mechanic's toolkit.
