S650 - ZF Design For GM And Ford

The S650, which is also known as the S6-650 is a rear wheel drive manual transmission with 6 forward speed and one rear speed, used in 2Wd and 4Wd configurations.

This is a heavy duty ZF design unit used in Ford and General Motors pickup trucks requiring a strong and flexible transmission.

Even though the units are similar for the Ford and Chevy sharing some parts there are differences between the two. For example the front half of the case, which includes the bell housing, is different and so is the tail housing.

Among the bearings, gaskets, seals, and synchros we also carry the forks, shafts, oil pump, key and spring kit and many other parts.
