Jims Sprockets & Chains

6 products

Jims sprockets and chains for Harley-Davidson reflect the same precision manufacturing philosophy that has made the brand a cornerstone of professional V-twin workshops for decades. Jims produces transmission sprockets and drivetrain components machined to exacting tolerances, drawing on deep knowledge of Harley-Davidson gearbox and final drive geometry across Big Twin, Sportster, Softail, Dyna and Touring platforms. Where generic sprocket suppliers offer approximate fits, Jims engineers their components with the dimensional accuracy that Harley-Davidson drivetrains demand — particularly important on transmissions where sprocket alignment directly affects chain wear and service life. Their transmission sprocket range covers classic four-speed and five-speed Big Twin gearboxes as well as the later six-speed configurations found on Touring and Softail Harley-Davidson models. Whether you are replacing a worn sprocket as part of a routine service or rebuilding a transmission from scratch, Jims components give professional-grade confidence in the finished result. Iron City Motorcycles, an authorised Harley-Davidson dealer in Leeds, stocks Jims precision drivetrain parts. Browse the full Jims Sprockets & Chains range below.
