S&S Rocker Arms And Shafts

8 products — part of all Rocker Arms And Shafts

S&S rocker arms and shafts give Harley-Davidson engine builders a precision-engineered valve train upgrade that delivers more consistent valve actuation and improved durability compared to factory components, particularly in engines running performance camshafts with aggressive lift and duration profiles. The rocker arm is the lever that converts pushrod motion into valve lift — in a standard Harley-Davidson engine it is a pressed or cast component, while the S&S equivalent is machined to tighter bore and geometry tolerances for reduced side-load on the valve stem and improved roller tip geometry. S&S supply rocker arm and shaft sets covering the main Harley-Davidson Big Twin and Sportster cylinder head configurations, with shaft diameters and rocker bores matched to deliver the oil film clearance that sustains valve train durability in both street and performance applications. Iron City Motorcycles, an authorised Harley-Davidson dealer in Leeds, carries S&S rocker arms and shafts alongside a comprehensive engine performance and rebuilding range.
