Description
Mountune’s Stage 1 Mk3 Focus RS gearbox upgrade offers the ability to cope with greatly increased power / torque outputs and improves traction, whilst maintaining maximum reliability.
Based around standard gears and internal parts that feature shot-peening for additional strength, in addition, every bearing is upgraded to a more reliable unit that features a steel race, rather than the OE plastic equivalent.
To further improve the mountune Stage 1 gearbox’s strength and to help improve drivability and enhance traction further, a Quaife ATB differential is also fitted as part of the upgrade.
The gearbox is available as an assembled, new transmission, or as a lower cost exchange unit (based on a fully-working donor gearbox).
