Transmission Top Cover Parts

53 products

Transmission Top Cover Parts for Harley-Davidson keep your gear-selection mechanism working precisely shift after shift. Iron City Motorcycles, an authorised Harley-Davidson dealer in Leeds, carries top cover components from MCS, James Gaskets and Samwel. Fitments include 1979-1986 four-speed Big Twin, 1984-1990 four-speed Sportster and 1952-1979 Big Twin platforms. Whether you need a replacement shift-fork shaft, detent springs, gaskets or a complete top-cover assembly, the right part restores crisp, positive shifting. These components are essential during any transmission rebuild and are often overlooked until a missed shift reveals the wear. Keep your gearbox selecting every ratio cleanly and reliably.
