Our advantages

The Toyota Yaris 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 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 maxiximum 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!

 

WHY CHOOSE KOTOUC GEARBOXES OVER XHIFT??

Why choose us over the competition? There are many reasons why we are the leader in 7 speed sequential gearboxes and when you look deeper into the product you can see why.

- Ability to fit aftermarket dual plated clutch! Dont get caught out! If you are increasing HP in the Yaris (who doesnt!!), there will come a time where you must install a dual plate clutch. Our gearbox is prepared to accept this necessary modification. Others will not.

- Billet case! The billet case ensures that the gearbox maintains minimum weight with maximum strength. Compared to a casting case with a tensile strength of 240MPa, the billet has a tensile strength of 580MPa!

- Strength and Durability! All our gears 1-7 a bigger, wider and stronger. With an average increase in width by over 17% and 7th gear being a whopping 31% wider!

- No modificatios! The gearbox will fit to your original holders, original clutch bearing and driveshafts. Swift installation without hassle.
