Crank Trigger Kit SBC w/7in Wheel

The MSD Ignition Crank Trigger Kit with 7-inch wheel is a high-precision ignition system component engineered for small-block Chevy engines requiring accurate crankshaft sensing and reliable spark timing control. This magnetic sensor-based crank trigger kit delivers the timing reference signal necessary for advanced ignition management systems, delivering consistent performance across varying engine loads and RPM ranges.

The kit includes a flying magnet trigger wheel, magnetic sensor pickup, trigger bracket, and mounting hardware designed for straightforward installation on a 7-inch balancer. The 7-inch wheel diameter provides reliable magnetic signal generation with minimal signal noise, critical for modern distributorless or multi-coil ignition systems that depend on precise crank position input. MSD Ignition's magnetic sensor design is industry-standard for small-block Chevy engine builds, ensuring compatibility with leading aftermarket ignition controllers and ECU platforms commonly deployed in performance and rebuilding applications.

This crank trigger kit is essential for engine builders, performance tuners, and Chevy engine enthusiasts transitioning to modern ignition management systems. It serves applications ranging from race engine builds and street performance builds to engine swaps where factory ignition sensors are unavailable or unsuitable. The complete kit format eliminates guesswork during installation, providing all necessary components in a single package.

Small-block Chevy platforms remain the most common choice for engine rebuilds and performance modifications across road racing, drag racing, and automotive restoration projects. A reliable crank trigger system is foundational to spark timing accuracy and overall engine reliability—especially critical in boosted or carbureted applications where timing precision directly impacts power delivery and engine longevity.
