The Raceline Duratec lightweight 7 ¼” and 8 ½” billet flywheels are machined from EN24T steel with an integral cut-in ring gear, heat treated and parkerized. The standard diameter flywheels are designed to use in conjunction with the stock Duratec starter motor. Raceline also offers a ‘compact’ version of the flywheel which retains the same clutch footprint but, by cutting the ring gear into the back face of the flywheel, allows for a smaller 268mm overall diameter. The ‘compact’ flywheel can only be used together with our ‘compact’ starter motor and together are made to neatly package inside our ‘compact’ bell housing – our smallest Duratec bell housing setup which in turn ties in with the critical dimensions of the Raceline dry sump system.Raceline stock a range of clutch options to suite all performance levels. If you can’t find a clutch listed below that is relevant to your application, please phone for advice.
