S&S 0.585" Valve Springs For Harley Big Twin

The S&S Street Performance .585" Valve Spring Kit elevates Big Twins outfitted with stock heads featuring 7mm and 5/16" valve stems. It is designed with single wire conical shape springs, optimized for high performance contexts and capable of accommodating camshaft lifts to 0.585".

With an installed height of 1.800" at a tension of 130 lbs and reaching 325 lbs at maximum lift, it stands as a critical enhancement for riders demanding more from their Big Twins.
