Description

The mountune Stage 1 Focus RS Gearbox Transmission is a rebuilt gearbox designed as a replacement for tired original gearboxes. It starts with a new Ford (Getrag) MMT6 gearbox, which is then disassembled, inspected, and reassembled with upgraded carbon-lined synchros and steel-caged primary bearings. An optional Quaife ATB differential can be added for increased traction and cornering performance. The gearbox is shipped assembled and ready for installation to minimize vehicle downtime.
