By reducing the weight of the flywheel over the standard Zetec SE item to as little as a half, the resulting reduced inertia gives better acceleration, especially in the lower gears. In addition, the reduced weight at the flywheel edges allows quicker gear changes, and increased engine braking. Comes with integral starter ring (ring gear is machined into the flywheel).

For use with the standard Zetec / Sigma cover.

Suitable for use with our Zetec SE to Ford Gearbox Bellhousing.
