Traxxas 10778X Front Planetary Differential Ring & Pinion Gear Set – Mini Maxx

The Traxxas 10778X Front Planetary Differential Gear Set is a genuine OEM replacement gear set for the Mini Maxx front differential. This set includes the 47-tooth ring gear and 12-tooth input gear — the two core gears of the front planetary differential assembly — restoring smooth, efficient power transfer to the front wheels.

Differential gears wear over time with heavy use and can strip under high-torque loads. Keeping a replacement set on hand means you can rebuild your front diff quickly and get back on the bash spot without waiting for parts.
