These gears are specifically designed for the front and rear axles of your vehicle, ensuring a seamless connection between the differential and central drive shaft. To learn more about how to install them properly, check out this comprehensive video guide: https://www.youtube.com/watch?v=A2Jj3CZOkWk. Unfortunately, the original gears I had were ruined because fine gravel got inside the rear differential gearbox. To prevent this issue from happening again, consider purchasing an additional gearbox cover that can be found here: https://www.thingiverse.com/thing:2784331. One notable feature of these gears is that the large bevel gear is identical to the ones used in the WLtoys 18428 and 18429 models. I designed these gears using Fusion 360, following a step-by-step guide found in this video: https://www.youtube.com/watch?v=xHNkGQePP-Y&t=265s. To my surprise, these gears have already survived two full batteries of high-speed driving and rough handling without any issues whatsoever.
