S&S Valves Exhaust

S&S sprocket shaft spacers serve the narrow but critical job of locating the engine sprocket on its shaft at the correct position for chain or belt alignment — and S&S is the brand you go to when the engine itself is an S&S long block or a crank using S&S-style Sportster dimensions. The spacers cover 1970–1999 OEM Big Twin excluding Twin Cam, 1955–1964 Big Twin with Timken-style bearing configuration, and 1986-up S&S style Sportster engines running a 1-1/4" Big Twin style sprocket shaft — the latter being a specific S&S conversion dimension that demands S&S sourced alignment hardware. Running a misaligned primary chain on a Harley-Davidson engine causes rapid wear; getting the spacer thickness right is the step that makes the rest of the drivetrain last. Iron City Motorcycles, your authorised Harley-Davidson dealer in Leeds, stocks S&S sprocket shaft spacers. Browse the full S&S Sprocket Shafts Spacers range below.
