Crank Trigger Wheel

The MSD Ignition Crank Trigger Wheel (ASY16719) is a precision-engineered ignition system component designed for high-performance engine builds and aftermarket ignition conversions. This trigger wheel is ideal for automotive enthusiasts and professional mechanics looking to upgrade their ignition systems for improved performance and reliability.

This crank trigger wheel replaces factory crankshaft-mounted components to enable accurate crank position sensing and optimized spark timing. It mounts directly to the crankshaft and works with compatible MSD ignition systems to deliver precise crank angle information to the ignition module. The design features accurately spaced trigger points that allow the ignition system to calculate engine speed and timing advance in real time.

Engine builders and mechanics rely on the MSD Crank Trigger Wheel for engine swaps, carburetor-to-fuel-injection conversions, and custom builds. Weighing just 0.7 lbs with compact dimensions of 6.55 x 1.35 x 9 inches, it integrates seamlessly into tight engine bays while maintaining the dimensional accuracy required for consistent sensor-to-trigger gap clearance.
