Jims Pinion Gears

Jims has built a formidable reputation producing precision engine components for Harley-Davidson, and their pinion gear range exemplifies that commitment to tolerance. The pinion gear is the critical driver at the heart of your Harley-Davidson's gear train, transmitting crankshaft rotation to the camshaft and oil pump with zero margin for slop. A worn or undersized pinion gear introduces timing errors that degrade performance, accelerate cam wear and eventually threaten engine integrity. Jims pinion gears are machined and heat-treated to exacting specifications, ensuring correct mesh with the pinion shaft and gear case components across Big Twin and Sportster applications. Iron City Motorcycles, your authorised Harley-Davidson dealer in Leeds, stocks Jims pinion gears as part of a comprehensive engine rebuild programme. Browse the full Jims Pinion Gears range below.
