Our advantages

AVAILABLE FOR:

Toyota Yaris GR / Toyota Corolla GR

The Toyota Yaris / Corolla GR just got serious! One of the most popular and in demand cars on the road and track now has a gearbox to suit! If you are looking to give your Yaris / Corolla GR the superstar treatment, then the 7 speed sequential gearbox from Kotouc Gearboxes is a must.

The 7 speed sequential gearbox is designed to fit in the original position as a replacement for the standard gearbox. Additionally, the same clutch, flywheel, starter motor, gearbox mounts, driveshafts all stay the same. There is no modification required to any of those parts, so installation is swift and time and costs are saved.

For those looking to upgrade, the sequential gearbox is prepared for a hydraulic clutch bearing, and mounting position for a piston in the case of paddle shifting. An oil outlet and inlet are available for the compatibility of an oil pump and cooler and a spare thread prepared for an oil temperature sensor.

Our dogring technology and engineering of the shifting barrel allows for the smoothest and cleanest shifting gearbox on the market. The arrangement of the gearing on the shafts allow for a 7 speed gearbox in a space usually that only 5 gears would fit. Moreover, the maximum width of the gears are 25mm!! Almost twice the size of the original Toyota gears.

With the popularity of this gearbox already high, there is no tome to wait! Call us today to get your hands on this amazing gearbox!
