Lighter and simpler than our previous valve springs, S&S Sidewinder springs are made from special ovate spring wire and have only one progressively wound coil. Since they do not add as much mass to the valve train as multi-coil spring packs, they offer high rpm capability with less spring pressure. Ideal for stock rebuilds and for mild performance cams.
