Distributor Gear Iron .500in

The Distributor Gear Iron .500in Shaft from ALLSTAR PERFORMANCE is a precision replacement component engineered for small-block Chevy V6 and V8 engines requiring synchronous ignition timing control. This iron gear drives the distributor shaft while meshing with the camshaft gear, making it essential for any engine rebuild, restoration, or high-performance application where reliable spark distribution is critical. Whether you're assembling a classic hot rod, rebuilding a street engine, or restoring a vintage Chevrolet, selecting the correct distributor gear ensures proper timing chain operation and consistent ignition timing across all engine speeds.

Manufactured from iron and finished with a durable black melonized coating, the Distributor Gear Iron .500in Shaft resists corrosion and wear while maintaining precise gear mesh tolerances with OEM Chevy cam gears. The .500-inch shaft diameter is the industry standard for small-block Chevrolet distributors, ensuring direct compatibility with original equipment specifications. Iron construction provides superior strength and longevity compared to brass or polymer alternatives, especially in high-RPM applications where gear loading intensifies. The melonized finish—a specialized surface treatment—enhances wear resistance and reduces galling between meshing gear teeth.

Technicians, engine builders, and Chevy enthusiasts rely on this distributor gear for stock restorations, custom engine builds, and timing chain replacements. Installation is straightforward when the timing cover is removed; the gear slides onto the distributor shaft and aligns with the camshaft gear teeth during engine assembly. This SKU ALL 81309 gear is manufactured to ALLSTAR PERFORMANCE's exacting standards and fits all small-block Chevy V6 and V8 configurations using the standard .500-inch distributor shaft. For anyone rebuilding a Chevrolet engine from the ground up or addressing ignition timing issues, this replacement gear delivers reliability and OEM-quality performance at a competitive price.
