Distributor Gear Polymer .491in Chevy

The Distributor Gear Polymer .491in Chevy is a high-performance replacement distributor gear designed specifically for Chevy V8 engines, ensuring precise ignition timing control. This gear is ideal for engine builders, restoration specialists, and performance mechanics who are upgrading or rebuilding Chevy V8 ignition systems.

Constructed from a durable polymer material, this gear offers significant advantages over traditional steel gears, including resistance to wear from constant meshing with the camshaft drive gear. It maintains dimensional stability across temperature cycles typical in high-RPM engine operation and reduces noise transmission through the distributor housing. The .491-inch shaft diameter conforms to OEM specifications, ensuring a proper fit and engagement with the distributor shaft.

Whether restoring a classic muscle car or servicing an aging engine, this distributor gear is essential for maintaining stable spark timing without slippage or premature wear. Its black finish provides corrosion resistance in engine bay environments, making it a reliable choice for both classic and modern Chevy V8 applications.
