Rocker Shaft Shims

3 products

Our range of Rocker Shaft Shims for Harley-Davidson provides the precision spacing shims used on the rocker shafts of 1966-1984 Shovelhead Big Twins. Iron City Motorcycles in Leeds is an authorised Harley-Davidson dealer, and we list shims sized to the original factory specifications used on these vintage Harley-Davidson top ends, where correct end float is central to a long-lived rebuild. You will find MCS workshop-standard shim packs, selected to match the material and dimensional tolerances these engines were designed around. Whether you are resetting rocker shaft end float during a Shovelhead top-end rebuild, replacing worn or missing shims after a head refresh, or returning a long-stored vintage Harley-Davidson engine to reliable service, the right shims are here.
