The COMP Cams melonized distributor gear is a single replacement gear made for Chevrolet small and big block distributors with a .491" shaft. Melonized iron construction offers enhanced wear resistance and timing accuracy compared with traditional bronze options, making it suitable for use with iron camshafts—both hydraulic and solid roller—where reduced friction and longer gear life are priorities.
