Pontiac Bronze Dist. Gear - .491in

The Pontiac Bronze Dist. Gear - .491in from COMP CAMS is a precision distributor gear engineered for classic Pontiac V8 engines requiring OEM-specification replacement components. Built for restorers, engine builders, and technicians who demand reliability in fuel distribution timing, this bronze gear serves as a critical synchronization element in the ignition system. Whether you're performing a complete engine rebuild or restoring a vintage Pontiac muscle car to factory specifications, this distributor gear ensures accurate cam-to-crankshaft timing correlation.

Manufactured in bronze material for durability and wear resistance, the Pontiac Bronze Dist. Gear features a 0.491-inch shaft specification that interfaces directly with Pontiac V8 distributor assemblies. Bronze composition provides superior lubrication characteristics and resists corrosion compared to ferrous alternatives, extending service life in both street and high-performance applications. The precise machining of the gear teeth ensures smooth mesh engagement with the crankshaft-driven cam gear, minimizing timing drift and maintaining consistent ignition advance throughout the engine's RPM range. This component's critical role in fuel delivery timing directly impacts engine efficiency, starting reliability, and emissions compliance.

Engine builders and Pontiac enthusiasts rely on this OEM-quality gear for any V8 rebuild requiring stock or near-stock distributor systems. Installation requires basic mechanical knowledge and proper timing verification post-installation to ensure optimal engine performance. This gear is particularly valuable for vehicles where original equipment has worn or failed, restoring proper ignition timing without modification to the existing distributor housing. Compatibility is confirmed for Pontiac V8 applications using the standard 0.491-inch shaft diameter; always verify fitment against your specific engine block and distributor assembly before purchase.
