P1046 FRONT WHEEL DRIVE TOURING CAR GEARBOX

The 1046 gearbox is a high performance front wheel drive touring car gearbox that has been designed specifically for the British Touring Car Championship and is suitable for the World Touring Car Championship.

The 1046 makes use of Rally derived gear ratios with minimised size and weight to reduce inertia. The gearchange system incorporates the latest polynomial barrel track design and low inertia gearchange rack to improve gearchange response and driver feel. The gears have been re-ordered to allow the overlap of barrel track profiles.

The low positioning of the gear cluster enables easy removal from the car under the chassis rail, and lowers the centre of gravity. The gear cluster is fully exposed when removed from the gearbox allowing quick inspection, and easy access for ratio changes.
