Crank Trigger Kit SBC w/7in Wheel

The MSD Ignition Crank Trigger Kit with 7-inch wheel is a precision ignition trigger system designed specifically for small-block Chevrolet engines that require accurate crankshaft position sensing. This kit is ideal for serious engine builders and mechanics who are working on high-performance street, strip, and race applications. It provides the reliable spark timing control necessary to maximize horsepower and ensure consistency across varying RPM ranges.

The 7-inch trigger wheel mounts directly to the crankshaft and operates in conjunction with a dedicated sensor to deliver continuous, real-time crankshaft position data to MSD's ignition systems. This magnetic trigger design is resistant to timing drift and wear that can occur with mechanical advance weights and springs, ensuring that spark delivery remains consistent with engine speed and load conditions. The compact design allows for easy integration into tight engine bay layouts, while the precision-machined wheel maintains concentricity to minimize timing variation.

This crank trigger kit is particularly beneficial for small-block Chevy builds, including 350 cu in stroker engines and modern LS conversions. It is compatible with various MSD ignition systems, making it a versatile choice for those tuning carbureted hot rods or preparing engines for competition. By eliminating the variability of traditional distributor-based ignition, this kit unlocks the full potential of your engine combination.
