The first stage of any car modification should include optimising the ratios of the gearbox to suit the engine characteristics as well as the intended application. With this first stage in mind we have produced a range of helical upgrade kits for the standard Sierra T9 gearbox.

Whether you are restoring a car which utilises the Sierra T9 gearbox or building a new kit car based around the Sierra driveline, these close ratio helical kits provide the perfect solution for the road based, trackday car.

These are truly the first step onto the motorsport transmission ladder.
