Distributor Gear Iron .491in

The Distributor Gear Iron .491in Shaft from ALLSTAR PERFORMANCE (SKU ALL 81308) is a precision-engineered distributor gear designed for Chevy V6 and V8 engines. This component is essential for engines requiring reliable distributor drive synchronization, and it serves as a direct replacement for worn or damaged OEM gears. Built from durable iron construction with a black melonized finish, this distributor gear ensures consistent ignition timing delivery across a wide range of Chevrolet applications.

The 0.491-inch shaft diameter is engineered to mate precisely with standard Chevy distributor housings, providing positive engagement and eliminating timing drift during engine operation. The iron construction offers superior wear resistance compared to lighter materials, while the melonized finish provides corrosion protection and extended service life in high-heat engine bay environments. This gear transfers rotational force from the camshaft to the distributor at the correct ratio, maintaining proper spark plug firing order and engine efficiency. Proper distributor gear function is critical for preventing timing issues that can lead to poor idle quality, hesitation, and reduced fuel economy.

Chevrolet engine builders, restoration specialists, and daily-driver owners benefit most from this replacement gear when rebuilding distributors or performing engine overhauls. It is compatible with most classic and modern Chevy V6 and V8 engine platforms, making it a versatile choice for both street and performance applications. Installation requires removal of the distributor assembly and careful alignment during reassembly to ensure proper timing. This single-unit gear is a cost-effective solution for restoring OEM-specification ignition performance without expensive distributor replacement.
