LS Reluctor Wheel 24-Tooth

The LS Reluctor Wheel 24-Tooth is a precision crankshaft trigger component designed for LS engine ignition systems and engine control modules. This reluctor wheel is crucial for builds converting older carbureted LS engines to modern fuel injection or upgrading from distributor-based ignition to coil-on-plug systems. It is ideal for engine builders and performance enthusiasts looking to enhance their LS engine setups.

Engineered to meet Chevrolet Performance specifications, this reluctor wheel ensures accurate crankshaft position sensing for optimal spark timing and fuel delivery. The 24-tooth design is the factory standard for LS engines, providing the correct tooth spacing to work seamlessly with factory or aftermarket crankshaft position sensors and engine management systems. Each tooth passes the CKP sensor at precise intervals, allowing the ECU to calculate engine speed and synchronize fuel injector pulse width with accuracy.

Engine builders and tuners replacing worn reluctor wheels or assembling stroker LS engines will find this part beneficial. It mounts directly onto the crankshaft nose, ensuring a reliable fit and sensor signal quality across thousands of engine revolutions. The OEM part number for this product is 12559353, making it a reliable choice for those working on LS1, LS2, and LS3 engine variants.
