Transmission Gears

17 products

Transmission Gears for Harley-Davidson are precision-machined components that transfer power through your gearbox. Whether you need replacement gears for a worn transmission or performance-cut gears for smoother shifting under high-torque conditions, quality internals are essential. Iron City Motorcycles, an authorised Harley-Davidson dealer in Leeds, stocks transmission gears from Andrews, MCS and Samwel for four-speed, five-speed and six-speed Harley gearboxes spanning Big Twin and Sportster platforms. From mainshaft gears and countershaft gears to close-ratio performance sets, these components are engineered for durability and accurate engagement. Replacing worn gears restores crisp shifting and protects the rest of your drivetrain. Browse the full range below.
