MSD 8624 Crank Trigger Kit Flywheel Magnet BBC 7in Red

The MSD 8624 Crank Trigger Kit is a high-performance ignition timing system designed for Big Block Chevy (BBC) engines with 7-inch flywheels. This kit uses a magnetic pickup mounted on the flywheel to provide precise crankshaft position information to your MSD ignition system, delivering accurate timing control at all RPM ranges.

Key Features:

• Flywheel-mounted magnetic trigger design for BBC engines
• Compatible with 7-inch diameter flywheels
• Red anodized finish for corrosion resistance and appearance
• Eliminates distributor timing fluctuations for consistent performance
• Provides accurate timing signal directly from crankshaft rotation
• Works with MSD 6-Series, 7-Series, and 8-Series ignition boxes
• Includes magnetic pickup, mounting hardware, and wiring

This crank trigger system mounts directly to the flywheel, providing a more reliable timing reference than traditional distributor-based systems. By reading timing directly from the crankshaft, you eliminate timing errors caused by distributor gear wear, timing chain stretch, and distributor shaft flex at high RPM. Ideal for high-performance street engines, race applications, and any BBC build requiring precise ignition timing control.
