S&S Sprocket Shafts

5 products — part of all Sprocket Shafts

S&S sprocket shafts for Harley-Davidson transfer engine power from the crankcase to the primary drive and are a critical drivetrain component on Big Twin models. The sprocket shaft operates under constant rotational load and significant lateral force from the primary chain — a worn or out-of-tolerance shaft introduces primary chain misalignment, accelerated chain and sprocket wear, and ultimately primary drive failure at high mileage or in modified engine applications running elevated power. S&S Cycle machines their Harley-Davidson sprocket shafts to tighter dimensional tolerances than OEM, with surface hardness matched to the demands of both stock and performance engine builds. S&S Cycle's engineering heritage in Big Twin performance means every sprocket shaft meets the standard that a rebuilt or performance-modified Harley-Davidson engine deserves. Iron City Motorcycles, your authorised Harley-Davidson dealer in Leeds, stocks S&S sprocket shafts. Browse the full S&S Sprocket Shafts range below.
