S&S Tappets

9 products — part of all Tappets

S&S tappets for Harley-Davidson are developed alongside S&S cam profiles — the lifter and cam combination ensuring bleed-down rate, bore diameter, and contact geometry are matched across the complete valvetrain package rather than left to chance. When you're running an S&S cam in a Harley-Davidson engine, S&S tappets remove the compatibility uncertainty that comes from mixing brands with different lifter specifications. S&S lifters cover Evolution Big Twin from 1984 through the XL Sportster range from 1986, with specifications matched to both stock-lift and S&S high-performance cam profiles. The slow-bleed high-performance variant suits builds where cam lift and valve spring pressure exceed OEM hydraulic lifter design parameters. Iron City Motorcycles stocks S&S tappets for the Harley-Davidson performance build that needs the valvetrain to work with the cam, not against it. Browse the full S&S Tappets range below.
