Gear Treatment
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. A Quaife ATB differential is added to ensure maximum traction and improved cornering.

Price is outright, no exchange is required, and because these are shipped
assembled and ready to install, downtime with your vehicle is reduced.

We recommend and use only MOTUL MULTI DCTF transmission fluid for improved shifting and performance, click
here for details.

he WPC process is unrivaled in treating engine parts and other surfaces that have contact points of friction.
