GM LS2 Timing Set 3-Bolt 4x Cam Reluctor

The GM LS2 Timing Set 3-Bolt 4x Cam Reluctor (CS1190) from ROLLMASTER-ROMAC is a precision engine synchronization component designed for LS2 engine platforms requiring OEM-specification timing control. This timing set delivers accurate camshaft-to-crankshaft phasing critical to engine startup, idle stability, and fuel injection pulse timing in modern GM LS architecture powerplants.

The 3-bolt mounting pattern and 4x cam reluctor tooth configuration match OEM LS2 specifications precisely, ensuring compatibility with factory ECU sensors and ignition timing systems. Weighing 3 lbs and measuring 1.6 x 1.6 x 10.2 inches, this component integrates directly into the LS2 front cover assembly. The reluctor ring's four-tooth design is engineered to provide the electronic control modules with accurate camshaft position feedback, which is essential for variable valve timing compensation, knock detection circuits, and diagnostic monitoring in modern powertrain management systems.

Engine builders, performance shops, and LS2 platform enthusiasts select ROLLMASTER-ROMAC timing sets when OEM-grade accuracy and sensor reliability are non-negotiable. Whether rebuilding a stock LS2, restoring an engine to original specifications, or replacing a damaged reluctor after a timing chain failure, this set ensures proper electronic fuel injection sync and eliminates no-start or running conditions tied to camshaft position sensing errors.

ROLLMASTER-ROMAC is recognized for OEM-equivalent timing chain and sprocket systems across the GM LS lineup. The CS1190 reluctor set maintains that reputation for precision manufacturing and tight sensor-to-ring tolerance control—qualities that directly prevent misfire codes, hard-start symptoms, and fuel trim instability in LS2 powered vehicles.
