Product Description
Genuine GM 24X Crankshaft Reluctor Wheel - GM #12559353
Genuine GM 24X Crank Trigger Wheel for Compatible LS Engine Applications Using a Black Crankshaft Position Sensor
Restore the correct crankshaft position signal configuration with this Genuine GM 24X Crankshaft Reluctor Wheel, GM part number 12559353. Designed for compatible GM LS engine combinations requiring a 24X crank trigger wheel, this OE replacement component is an ideal choice during a crankshaft replacement, short-block rebuild, rotating assembly upgrade, or complete engine build. Confirm the existing reluctor count, crankshaft position sensor color, ECM calibration, and engine-management configuration before installation.
Key Features & Benefits
- Genuine GM Replacement Part: Genuine GM 24X crankshaft reluctor wheel, GM part number 12559353, for compatible engine combinations requiring the original 24X crankshaft trigger configuration.
- Correct 24X Crankshaft Signal Configuration: Designed for applications using a 24X reluctor wheel and the corresponding compatible crankshaft position sensor, wiring harness, ECM, and calibration.
- Ideal During Engine Rebuilds: A practical replacement when servicing the crankshaft, replacing a rotating assembly, building a short block, or completing a full LS engine rebuild.
- Helps Maintain OE-Style Engine Management Compatibility: Matching the correct reluctor wheel count to the sensor and ECM configuration is essential for proper crankshaft position signal operation.
- Black Sensor Identification Reference: Compatible 24X applications use a black crankshaft position sensor, providing a useful visual confirmation point before ordering parts for an existing engine combination.
Specs
- Brand: Genuine GM
- GM Part Number: 12559353
- Product Type: Crankshaft reluctor wheel
- Reluctor Count: 24X
- Primary Use: Compatible GM LS crankshaft position signal applications
- Sensor Identification: Black crankshaft position sensor for 24X applications
Notes
- 24X vs. 58X Verification Required: Confirm your engine requires a 24X reluctor wheel before purchase. 24X applications use a black crankshaft position sensor, while 58X applications use a grey sensor.
- Sensor Location: The crankshaft position sensor is located at the back of the engine block near the oil pan, on the passenger side of the engine, just above the starter.
- Engine Management Compatibility: Verify the reluctor wheel count matches the intended crankshaft position sensor, wiring harness, ECM, and calibration before final assembly.
- Installation Note: Reluctor wheel replacement requires engine disassembly and proper crankshaft assembly procedures. Confirm all component compatibility before installation.
Key Fitments
- 24X Reluctor wheels were primary used on 1997-2005 LS Engines.
- Also used on some 2006 LS Engines.
