Set up in 1999, Deland Car Accessories Co., Ltd. is a professional China sierra gearbox manufacturer and designer. It has years of OES and OEM sierra gearboxes production experiences and passed ISO9000 and the TUV certification of ISO/TS16949 quality system. Therefore, we can better fulfill customers' specifications and satisfy their changing needs, such as Ford, Opel, Benz, BMW, Nissan, Toyota, Mitsubishi, Mazda, Isuzu, Hyundai, Kia and Truck series.

The gearbox is from Ford Sierra (Mercury Merkur XR4Ti in the USA), 1.6L & 1.8L: 1982-91, & 2.0L: 1982-87. The gearbox is not included in the kit, but may be procured locally or through the kit supplier. Various alternative gear ratios can be provided including a close ratio gearbox and a standard ratio gearbox with a higher first gear ratio of 2.98:1. The vehicle speedometer will need calibrating. Several companies are able to do this. Sierra is the most common set of ratios used in the MGA 5 speed.
Granada is more difficult to obtain. In the USA the Ford Merkur box is the same as the Type 9. Many gear ratios are available on special order. 2.445 c/r 1st gear in a Twin Cam can be a pig on hill starts. 3.640 std. barely gets across a stop road junction without changing (with std. diff.) 2.930/2.830 1st in the Sierra/Granada is a nice compromise. Includes paint and sealant. Supply drain plug and mill, drill and tap main case to suit (As drain plugs are not fitted from factory). 12 month guarantee.
