mountune Stage 1 Focus ST Gearbox Transmission
Our Stage 1 Focus ST gearbox is a great solution for those looking to replace their tired and worn original gearbox.
We start with a brand new original Ford (Getrag) MMT6 gearbox, then each box is disassembled and inspected to ensure each part and component meets specifications. We then reassemble the gearbox with our carbon-lined upgraded synchros and steel-caged primary bearings.
Price is outright, no exchange is required, and because these are shipped assembled and ready to install, downtime with your vehicle is reduced.
