STAR RACING High Lift valve spring kit

Anyone who has ever heard of the brand name Star Racing knows that it is synonym to Horsepower. Star Racing founder George Bryce is one of the "G's" in G-Squared Motorsports, the world championship winning cooperation between Star Racing and S&S Cycle Inc.. They have taken the most power out of any petrol burning Harley-Davidson and reached 200MPH in just 6 seconds. Now all of George his knowledge is available in these Star Racing cams that literally push all boundaries when it comes to usable horsepower. Apart from horsepower and torque these cams even let your Twin Cam sound like a Harley should sound.
