Quaife Toyota 6-Speed Sequential Gear Kit (C52)

QKE12E

The QKE12E six-speed sequential gearkit is purpose designed for the 4A-GE and 4E-FE engines, using the C52 transmission.

A direct replacement for the standard 5-speed H-pattern Toyota transmission, the QKE12E six-speed sequential gearkit package includes a specially strengthened outer gearbox casing and sequential gearchange mechanism, which features a compact, drum style design for an ultra rapid gear shift.

QKE12E utilises the original bellhousing half of the casing, allowing the retention of the Toyota clutch, differential, driveshafts and mounting points. The QKE12E offers optimised gearing with a choice of five shorter overall final drives and two sets of close-ratio intermediate gears with a straight cut tooth form.

These design elements enable Quaife to minimise transmission power losses and allow drivers to easily keep the 4A-GE and 4E-FE engines working in their power band, while delivering a top speed more suited to the needs of competition.

Key technical features of QKE12E include:-

• Strengthened gear casing and stock mounting points

• Ultra fast sequential gearshift with straight cut, close-ratio gears

• Retains stock Toyota clutch, diff, driveshafts and mounts

• Optional Quaife ATB (QDF15E) and final drive ratio (QRE12E) available
