      The need for increased performance has led TODA Racing to design a single progressive coil spring to replace the standard double valve springs. As well as allowing valve lifts of up to 13.00mm, the material and the coil springs natural frequency have all been optimized. Ideal also for Drop-in camshafts for people wanting to be able to extract power to higher rpm than the standard valves will allow.

      SuperTech Dual Valve-springs, Supertech dual bases, Ti retainers and collets
      Supertech dual valve springs are designed and manufactured to reduce valvetrain harmonics, increase durability, and provide an increase in performance for your high performance racing engine. All their dual valve springs are manufactured using superclean chrome silicon vanadium alloy and then heat treated, stress relieved and shoot peened to help improve the fatigue life of the spring. Springs we use are rated to 95lbs but ratings are available at 80lb, 82lbs and 97lbs. Springs come complete with matching Supertech bases, retainers and 7' collets
