X Shift Gearboxes has developed a stronger hypoid gear set for the front transfer case 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, resulting in larger teeth that can handle higher torque and greater impacts. Our stronger hypoid gear set features 32 teeth on the crown gear and 14 teeth on the pinion, compared to the original, which has 39 teeth on the crown 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. The gear set is made from high-alloy steel and finished using the REM isotropic superfinishing method for a superior surface finish.
For a hassle-free replacement, we offer installation at X Shift Gearboxes. Simply send us your original transfer case, and we will take care of the rest.
If you are interested in the hypoid gear set or want more information, please contact our sales department or our dealers.
