Ring - Crankshaft Position Sensor Exciter

The Crankshaft Position Sensor Exciter Ring from Chevrolet Performance is a precision timing component designed for Chevrolet small-block and big-block engines. This exciter ring acts as the trigger mechanism that allows the crankshaft position sensor to accurately read engine rotation, ensuring precise ignition timing signals are delivered to the engine control module.

Constructed as a compact ring assembly, this exciter ring features precisely spaced magnetic reference teeth that rotate with the crankshaft. As the ring spins, these teeth pass by the stationary crank sensor, generating the electronic pulse signal that the engine's computer uses to determine crankshaft position and rotational speed. This level of precision is critical for modern fuel injection systems and variable valve timing.

Mechanics and engine builders will find this exciter ring essential for both rebuilding high-performance stroker engines and replacing worn timing components on stock builds. Its design is engineered to tight tolerances, ensuring consistent sensor readings across the entire RPM range, from idle cruising to wide-open throttle acceleration.
