X Shift Gearboxes has developed a stronger hypoid gear set for the front transfer assembly of the Toyota GR Yaris. With this product, you can avoid issues with the original gear set, which is weaker and prone to gear tooth damage. Our new gear set has fewer teeth than the original, allowing use of larger teeth that can handle higher torque and greater impacts. Stronger hypoid gear set features 32 teeth on the ring gear and 14 teeth on the pinion, compared to the original, which has 39 teeth on the ring gear and 19 teeth on the pinion. The gear ratio is very similar to the original and closer to a 1:1 ratio between the front and rear axles.
Not only gearing, but also input shaft was improved to endure most extreme conditions. New design of the shaft with thicker wall and securing nut instead of snap ring results in more durable solution. Both gear set and input shaft are made from high-alloy steel and finished using the REM isotropic superfinishing method for a superior surface finish.
Improved hypoid gearing and input shaft are fully compatible with OEM transfer case, but we strongly recommend using our advanced Toyota GR Yaris Billet Transfer Case.
