S&S Pinion Shafts

5 products — part of all Pinion Shafts

S&S pinion shafts for Harley-Davidson are precision-ground engine components that carry the pinion gear and drive the cam train and oil pump from the crankshaft. A worn or damaged pinion shaft causes timing drift, oil pressure loss and progressive wear through the gear train — problems that compound quickly in a high-revving V-twin and ultimately threaten engine longevity if left unaddressed. S&S machines their Harley-Davidson pinion shafts from high-grade steel and grinds them to the close tolerances required for correct gear mesh and bearing fit, making them a trusted choice for engine rebuilders who demand the same quality they expect from S&S's broader performance engine programme. Iron City Motorcycles, your authorised Harley-Davidson dealer in Leeds, stocks S&S pinion shafts as part of a comprehensive engine rebuild and performance components range.
