The five-speed sequential gearkit has been design for Ford's M66 gearbox, fitted predominantly to the Mk2 Focus models, including ST and RS derivatives, but also some Volvo models.
A drum style shift mechanism provides fast and reliable gear changes while five wider-than-standard gears provide additional strength. The QKE45Z is available with two final drive options for straight-cut gear sets and one helical engagement option, as seen below.
The company has also developed a bespoke gearbox breather system for the Mk2 Focus, a necessity when running the QKE45Z. The system mounts to the bulkhead and includes a breather tank and filter alongside race lines and fittings. For flat-shifting, a Geartronic ignition-cut module is available when retaining the OE Powertrain Control Module (PCM). For alternative aftermarket PCMs, a load-cell is available.
Iterations of many iconic Volvos use the M66 and the QKE45Z can be adapted to suit the following: C30, S40, V50, S60, C70 and V70. In non-RS Focus and Volvo applications, a Quaife ATB limited slip differential is recommended, if not being fitted to a Focus RS (where it was fitted as standard) and is also available through mountune.
