MCS Sprocket Shafts

13 products — part of all Sprocket Shafts

MCS sprocket shafts for Harley-Davidson are the critical engine output shafts that transfer power from the crankcase to the primary drive. A worn or damaged sprocket shaft introduces primary chain or belt misalignment, excess runout and progressive wear that propagates through the entire drivetrain. MCS stocks sprocket shafts across the Harley-Davidson Big Twin and Sportster engine families, sourced to OEM dimensional tolerances to ensure correct bearing fit, seal retention and sprocket alignment on installation. Replacing a worn sprocket shaft during an engine or primary rebuild is the correct approach to preventing repeat primary drive failures. Iron City Motorcycles, your authorised Harley-Davidson dealer in Leeds, stocks MCS sprocket shafts as part of a comprehensive engine components programme alongside primary and transmission parts.
