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 multicoil spring packs, they offer high rpm capability with less spring pressure for cams up to .585" lift.
Features and Benefits:
- Lower spring force results in reduced valve train noise, increased valve stability, and longer valve train component life
- Excellent upgrade for stock rebuilds and mild performance cams
