Purple anodized aluminum flywheel.
Includes brass collet and steel pins.
Implementation cannot take place without research and development. Our Ultra Light aluminum flywheels are no exception. Ultra Light flywheels are CNC-machined from lightweight 6061-T6 billet aluminum This flywheels can be used with any stock or aftermarket clutch 2 shoes setup, but we recommend our Ultra Grip 7075 T6 clutches.
Our flywheel weights are chosen very carefully. They are the perfect balance of strength and light weight. Because of their light weight, energy normally used to turn the heavy stock flywheel is now used to turn your drive wheels! In addition, the reduced mass allows the engine to rev faster and get you into your power band more quickly.
You might need a Clutch nut shim. (OFN10099)
