Equip your 2013-2018 Focus ST with a flywheel from SPEC Clutch. By reducing the rotating mass, SPEC's lightweight aluminum flywheel is able to free up power. The flywheel features billet construction for strength and durability. Only the highest quality aluminum is used to achieve a .001 machine tolerance. This guarantees a flat seating surface for the clutch and also perfect rotational qualities for perfect balance and extended engine life. SPEC manufactures replacement parts as this is a rebuildable flywheel. Infinite rebuildability means no buying brand new flywheels at full price.

Features and Benefits:
- Billet Aluminum Flywheel
- Lighter Rotating Assembly
