Distributor Gear Polymer .500in Chevy

The COMP CAMS Distributor Gear Polymer .500in Chevy is a precision-engineered timing component designed for Chevrolet V8 engines requiring OEM-specification distributor shaft compatibility. Built from carbon ultra-poly composite material, this distributor gear delivers the durability and wear resistance necessary for reliable ignition timing control in both stock and mildly modified Chevy V8 applications.

The .500-inch shaft diameter matches the standard Chevrolet V8 distributor bore, ensuring proper fit and eliminating timing inconsistencies that plague worn or incompatible gears. Carbon ultra-poly composite material resists the tooth wear and backlash that develops in aluminum alloy gears over extended engine operation. The black finish provides corrosion resistance, particularly important in high-temperature under-hood environments where moisture accumulation accelerates oxidation. Each unit is manufactured to COMP CAMS' established tolerances, guaranteeing interference-free operation with existing distributor components and cam timing specifications.

This distributor gear is essential for Chevy V8 engine builders, restoration specialists, and performance enthusiasts addressing timing chain wear or replacing original equipment that has developed excessive gear tooth wear. Whether rebuilding a classic small-block or preparing a street engine for long-term reliability, a fresh composite gear eliminates variables that compromise ignition timing stability. Weighing only 0.16 lbs, it imposes no additional rotating mass on the cam timing train while delivering superior longevity compared to softer aluminum alternatives.
