LS Reluctor Wheel 24-Tooth

The LS Reluctor Wheel 24-Tooth from Chevrolet Performance is a precision crankshaft sensor trigger ring engineered for GM LS-series engines and LS-based powerplants. This component is essential for modern engine management systems, providing accurate crankshaft position data to the engine control module (ECM) for proper fuel injection timing, ignition sequencing, and spark curve optimization. Whether you're building a street machine, a restomod classic, or a high-performance crate engine installation, the reluctor wheel ensures reliable electronic fuel management and consistent engine operation.

The 24-tooth design creates distinct magnetic pulses as it rotates past the crankshaft position sensor, allowing the ECM to track engine speed and piston location with precision. This reluctor wheel mounts directly to the crankshaft balancer or harmonic damper assembly and is compatible with both carbureted and fuel-injected LS conversions when paired with appropriate LS engine control harnesses. The compact form factor—measuring 7.65 x 1.4 x 7.7 inches and weighing just 1.31 lbs—makes installation straightforward in tight engine compartments without adding significant mass or complexity to your rotating assembly.

Technicians and enthusiasts performing LS engine swaps, crate motor installations, or fuel injection retrofits rely on this OEM Chevrolet Performance reluctor wheel to achieve clean idle quality, accurate fuel metering, and repeatable timing control. The 24-tooth configuration is the standard tooth count for most modern LS variants, ensuring compatibility with factory ECM calibrations and standalone engine management systems commonly used in performance and street applications. Proper installation requires alignment with the corresponding crankshaft sensor for optimal signal integrity.
