Ford MMT6 gearbox synchroniser set. Upgraded carbon friction surfaces.

Suits 6-speed gearboxes found in the Focus ST and RS.

These synchros markedly improve shifting feel – a fantastic upgrade whether using your car for daily driving or as a weekend track weapon.

For street cars we recommend Amsoil Synchromesh; for track-oriented vehicles you may be better off with the heavier Amsoil 75w90GL4.
