Crank Trigger Wheel

The MSD Ignition Crank Trigger Wheel (ASY16719) is a precision ignition timing component designed for high-performance engine management systems. This flying magnet crank trigger wheel features a 6.250-inch balancer diameter and is constructed from aluminum with red anodized finish, providing reliable magnetic signal generation for MSD digital ignition systems and compatible electronic timing applications.

The red anodized aluminum construction offers both corrosion resistance and visual identification on the engine block. At 0.7 lbs, the crank trigger wheel maintains a lightweight profile while preserving the structural integrity required for accurate crankshaft position sensing. The 6.250-inch balancer dimension is critical for proper timing signal detection—this size specification ensures compatibility with MSD Flying Wheel Crank Trigger Kits and maintains the precise spacing necessary for consistent magnetic pickup operation across the RPM range.

This component is essential for engine builders and performance technicians integrating MSD ignition systems into custom engines, street rods, race applications, and engine swaps where OEM ignition components are being replaced with aftermarket electronic systems. The crank trigger wheel works in concert with MSD's timing control modules to deliver precise spark advance curves tailored to fuel type, load conditions, and RPM. Proper installation and alignment of this component directly impacts engine startup, idle quality, and overall combustion efficiency.

MSD Ignition specializes in programmable digital ignition systems used across motorsports, marine propulsion, and performance automotive applications where precision timing control is non-negotiable. The crank trigger wheel is a core wear component that may require replacement during system rebuilds or major engine service intervals.
