Lunati 89032 Everwear Cast Distributor Gear Chevy V8 HEI 0.427" Shaft

The Lunati 89032 Everwear Distributor Gear is a cast steel distributor gear engineered for Chevrolet V8 and V6 HEI applications using a 0.427-inch diameter shaft. Designed as a direct replacement or performance upgrade, this gear delivers reliable ignition timing transfer between the camshaft and distributor in demanding street and race environments.

Lunati's Everwear series was developed using a proprietary material formulation combined with a special nitride case-hardening process, resulting in a gear surface that resists premature wear and failure. Unlike standard cast iron or bronze gears, the Everwear design is compatible with all common steel camshaft core materials, including 1050, 5150, 5160, 8620, 8650, and 8660 alloys ? eliminating the guesswork when matching a distributor gear to your camshaft.
