Quaife QBE46Z Ford Focus Mk3 ST250 (2WD) & RS (4WD) 5-Speed Sequential Gearbox
QBE46Z is a five-speed sequential conversion gearbox for the Ford ST250 2WD and Ford Focus RS Mk3 4WD gearboxes. QBE46Z features a replacement Quaife outer gearbox maincase, which houses five straight-cut, close-ratio gears, and a compact, drum style sequential gearchange mechanism. This combines with an open face dog design to ensure a rapid, positive sequential gear shift.
Careful design by Quaife allows the QBE46Z to retain the original bellhousing, plus the stock Ford clutch, differential, driveshafts and mounting points. This enables easy installation of the QBE46Z sequential gearbox into the ST250 and RS.
Key features of the QBE46Z include:
– Complete, built sequential conversion gearbox, compatible with both ST250 2WD and RS 4WD gearboxes
– Gearkit reuses original bellhousing from donor 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
– New generation of gearchange mechanism allows fitment into front or rear wheel drive configurations
– Compatible with flatshift systems
– Includes oil temprature sensor
– Supplied with either a manual lever and cable or air actuator for paddleshift

Quaife QKE45Z Ford/Volvo M66 5-Speed Sequential Gearkit
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, but are not limited to, both FWD and AWD 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 and both FWD & AWD Volvo models fitted with the M66 gearbox
- Gearkit retains original bellhousing from gearbox
- Optional Quaife ATB (except Focus RS)
- 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
