Replacement Reluctor - 6 Cylinder

The MSD Ignition Replacement Reluctor for 6-Cylinder engines (MPN PRD13952) is a precision trigger wheel assembly engineered to restore accurate crankshaft position sensing in electronic ignition systems. This reluctor ring sits at the heart of any distributor-less or computer-controlled ignition setup, translating engine rotation into precise timing signals that the engine control module uses to fire cylinders at exactly the right moment. A worn or damaged reluctor compromises combustion timing, causing rough idle, hesitation, misfires, and failed emissions tests.

MSD's reluctor is designed with tight tolerances to ensure consistent air-gap spacing relative to the pickup coil sensor. Any variance in tooth geometry or radial runout degrades signal quality and creates timing errors. This OEM-spec replacement maintains the exact tooth profile and magnetic properties needed for clean, repeatable pulse generation across the full RPM band. The compact 1.75 x 0.65 x 2.75-inch design fits within standard six-cylinder crankshaft configurations, and the minimal weight of 0.08 lbs means negligible rotating mass—critical for high-RPM stability in performance engines.

Technicians rebuilding electronic ignition systems, engine builders upgrading to MSD performance ignition platforms, and shop owners restocking repair inventory rely on reluctor rings like this one. Whether diagnosing a no-start condition, replacing a crankshaft sensor setup, or assembling a complete ignition harness, having the correct reluctor specification ensures the signal chain is intact. This reluctor is purpose-built for six-cylinder applications where precise cylinder identification is non-negotiable for proper sequential or wasted-spark firing.
