S&S Valve Springs

S & S valve springs are made from finest chrome silicon steel to resist highest strain. The kit for Shovelheads includes upper aluminum valve collars and may also be used on Panheads. Kits for Evo Big Twins and Sportster include an outer spring, inner spring and inner harmonic spring for each valve. Available with steel top collars which are drilled for lightness and cooling or superlight titanium top collars and valve keys.

Max. travel is shown without safety clearance. A minimum clearance of .050“ is recommended. Closed valve spring pressure is measured with stock upper and lower valve spring collars and stock installation height, if valve spring collars are supplied with springs it is measured with these collars. Open valve spring pressure is measured at max.possible lift. All valve spring kits are for one motor and without valve spring collars unless noted otherwise.
