Crank Position Sensor

The Crank Position Sensor is an OE replacement unit engineered for GM LS-series engines, delivering reliable crankshaft position feedback essential for precise engine management and ignition timing. This 24x pulse crankshaft position sensor is designed for owners and technicians who demand factory-level performance and durability when servicing LS-based powerplants. Whether you're rebuilding a classic muscle car, maintaining a performance truck, or restoring a modern LS swap, this sensor ensures your engine control module receives accurate rotational data for optimal combustion and reliability.

The Crank Position Sensor operates by generating 24 pulses per crankshaft revolution, allowing the ECU to precisely calculate engine speed and timing events for fuel injection and spark advance. This inductive Hall-effect design responds directly to reluctor ring teeth on the crankshaft, providing real-time positional feedback without electronic drift or calibration loss over time. The compact form factor—measuring 2.3 x 1.55 x 4.1 inches and weighing just 0.08 lbs—allows straightforward fitment into tight LS engine bays while maintaining the electrical integrity and durability of the original Chevrolet Performance specification.

LS engine builders, performance shops, and DIY enthusiasts benefit from this OE-matched sensor because it eliminates guesswork and compatibility concerns during installation and tuning. Direct bolt-in fitment and standard GM LS-series mounting ensure plug-and-play integration with your existing harness and ECU calibration. Proper crank position sensing is critical to preventing rough idle, hesitation, hard starting, and check-engine diagnostics—making this Chevrolet Performance unit an essential reliability upgrade for any LS-series application from street engines to race-prepped builds.
