We carry SPEC's full line of billet super light weight aluminum and billet steel flywheels. Your engine, gearing and vehicle weight are factors in determining which SPEC billet steel or billet aluminum flywheel is best suited for your application. Please inquire with an S & T MotorSports technical assistant for recommendations
BILLET ALUMINUM
SPEC billet aluminum flywheels are also CNC machined and exceed SFI standards for high stress racing applications. These units are recommended for highly modified street or racing vehicles, and for mildly modified street cars that can benefit from reduced rotating mass without the loss of daily drivability. Consult a S&T Motorsport technical assistant for recommendations on your specific needs. The body of the flywheel is made of tempered aluminums, either 6061 T6 or 2024T3, for ultimate strength and lightest possible weight. The 1/4 inch thick friction plate is a 1050 high carbon alloy, for incredible durability with any friction disc material, even iron. The plates are secured to the body by aerospace fasteners or stainless steel rivets, depending on the application. These fasteners were chosen because of their exceptional strength and corrosion resistance. The ring gears are pressed on and secured wit h grade 10 fasteners. The gear is also heat treated for longevity. They are effective, durable and almost too pretty to install! Typical weight is 10 lbs.
BILLET STEEL
SPEC billet steel flywheels are machined from the highest quality materials and exceed SFI safety standards for high rpm racing applications. They are precision ground to mate perfectly to the crank with minimum run out and provide a true and reliable surface to mate with the variety of friction materials we offer. They are recommended for heavy vehicles in a drag racing application and for mildly modified street/strip cars.
