The new 6689 billet flywheel from ARC Racing has an ultra low drag fin design that will greatly reduce air drag on your AKRA/NKA racing engine, while still moving enough air for cooling. Less air drag on the flywheel means more power freed up throughout the power curve, especially on the top end. This flywheel is designed for oval track racing. Will work with stock pull rope and OEM coil.
