Fully rebuilt 5 speed Sierra Type 9 gearbox converted to 2.74 first gear ratio. These boxes have been used successfully in the UK in applications such as drag and circuit racing. Includes new bearings and seals and professional conversion to layshaft and first gear on mainshaft to 2.74 first gear (standard first gear is 3.3 or 3.6). First and second gear have been converted to run on needle roller bearings reducing stress.
Great box for a Clubman lotus 7 style car or where a lower diff is used and the taller first gear will provide benefits. Sold outright no exchange needed. Shifters offered at discounted pricing when a box is purchased. Professionally rebuilt by qualified experienced technician with many years experience with these gearboxes.
