Quaife QKE45Z Ford/Volvo M66 5-Speed Sequential Gearkit

Ford Focus RS Mk2

Quaife are excited to announce the launch of QKE45Z, our 5-speed sequential gearkit suitable for Ford’s M66 gearbox.

This transmission is fitted predominantly to the Mk2 Focus, and we’re expecting a high take-up from owners of ST and RS derivatives of Ford’s second generation hatchback.

It’s also worth noting that the M66 gearbox, (as with many components made during the period of Ford’s Premier Automotive Group), was fitted to a number of Volvo models too, expanding the scope of QKE45Z even further. Applicable Volvos will include iterations of C30, S40, V50, S60, C70 and V70, (for those keen on recreating a more up-to-date version of the 850 used in the BTCC).


Key features include:

  • Suitable for Ford Focus Mk2 with M66 gearbox
  • Gearkit retains original bellhousing from gearbox
  • Optional Quaife ATB
  • Strengthened outer casing
  • Drum style shift mechanism for fast reliable gear changes
  • Choice of straight cut or helical gears
  • Retains OEM clutch, differential, driveshafts and mounts
  • 5 wider than standard gears for additional strength
  • New generation of gearchange mechanism allows fitment into front or rear wheel drive configurations

Gear ratios:

1st            2nd         3rd        4th          5th

2.833     2.067      1.556      1.263      1.087    Straight cut

2.867     1.900      1.400      1.107      0.935    Helical

Final drive:

Quaife QBE46Z Ford MMT6 5-Speed Sequential Gearbox

Ford Focus RS Mk3

Ford’s MMT6 gearbox is most associated with the current generation Mk3 Focus ST and RS.

One of the most popular and accessible hot hatchbacks on UK roads, the Mk3 Focus ST was launched in 2012, producing a healthy 252bhp from the company’s 2.0-litre EcoBoost engine. Although it did away with its predecessor’s Volvo sourced five-cylinder engine, which was beloved by many an enthusiast, the current Focus ST has still remained at the upper-end of the hot hatch rankings. Practicality was addressed by the firm sticking with a 5-door only format, along with interestingly, an estate.

The current Focus RS was launched to great fanfare in early 2015 and has been powered by the 2.3-litre turbocharged inline-four engine, also found in the EcoBoost Mustang. Producing 350 bhp with power being sent to all four wheels, the RS can undertake the 0-62 mph sprint in just 4.7 seconds.


Interestingly, many owners of these two sporting Fords have opted to fit Quaife’s Automatic Torque Biasing Differential to improve traction and increase their vehicle’s performance envelope. Indeed, the ATB differential for the Mk3 Focus RS is now approved by Ford when fitted by Mountune or a Ford authorised dealership.

The Quaife QBE46Z 5-speed sequential gearbox is a product designed specifically for use in the Mk3 Focus ST & RS, vehicles initially fitted with Ford’s MMT6 transmission.

Key features include:

  • Gearkit reuses original bellhousing from gearbox.
  • Drum style shift mechanism for fast reliable gear changes.
  • Retains OEM clutch, differential, driveshafts and mounts.
  • Optional Quaife ATB differential.
  • Strengthened outer casing.
  • 5 wider than standard gears for additional strength.
  • Choice of straight cut or helical gears.
  • New generation of gearchange mechanism allows fitment into front or rear wheel drive configurations.
  • Compatible with flat shift systems.
  • Includes Oil Temperature Sensor.
  • Supplied with either a lever and cable or air actuator.
