Clutch Masters steel flywheels are CNC-machined, precision-balanced components built to work exclusively with FX100–FX500 conversion clutch kits and not OEM clutches. Manufactured in the USA from billet cores and finished—aluminum units receive Type 3 hard anodizing while steel units are black oxide coated—each flywheel is zero-balanced and SFI 1.2 certified. They are engineered for precision fitment and consistent rotational balance in motorsports and conversion applications.
