New distributor gears from COMP Cams® provide the universal compatibility often associated with bronze gears for use with any steel, cast iron or ductile iron camshaft, but without the wear concerns.
COMP Cams® Melonized Distributor Gears are designed to work with Big and Small Block Chevy, Ford 302 and Ford 351W applications. The melonizing nitriding process was originally developed by OEMs, including GM and Ford. As opposed to bronze gears, melonized versions are less wear-prone and feature better timing accuracy and higher strength than any other universally compatible distributor gear option. The greater wear resistance and higher precision of COMP Cams® Melonized Gears also provide less spark scatter (more accurate timing) than is possible with a bronze gear.
