ShareGoo RC Car Belt Drive Gear Set – 3.2mm Upgrade for Axial SCX10 SCX10-II 90046 (Black)
ShareGoo RC Car Belt Drive Gear Set – 3.2mm Upgrade for Axial SCX10 SCX10-II 90046 (Black)
The ShareGoo RC car belt drive transmission gear system is a metal upgrade part designed for the Axial SCX10 and SCX10-II 90046 1/10 scale RC crawler. It uses a belt drive with a 13:36 gear ratio, a 3.2mm small gear aperture, and a 132mm belt length to help reduce noise and improve smoothness. This set is for hobbyists aged 14 and up who want to modify their RC gearbox for quieter, more reliable performance.
How does the belt drive reduce noise compared to standard gears?
Belt drive systems transfer power through a flexible belt rather than metal-to-metal gear meshing. This design absorbs vibration and minimizes the high-pitched whine common with traditional gear drives. For RC crawlers, this means a quieter operation, which is especially helpful during indoor or late-night runs where noise can be a concern.
Compatibility with Axial SCX10 Models
This upgrade part fits the Axial SCX10, SCX10-II, and 90046 1/10 RC crawler cars. It is specifically for the transmission gearbox area. Before purchasing, ensure your vehicle model matches these compatibility details. The kit is intended as an upgrade, so it may require some mechanical skill to install.

Frequently Asked Questions
Will this work with my Axial SCX10 III or other versions?
This part is listed as compatible with Axial SCX10, SCX10-II, and 90046. Other versions (like SCX10 III) may have different transmission layouts. Check your vehicle's gearbox design before ordering.
Is it hard to install?
Many hobbyists find the installation straightforward, but it does require some familiarity with RC gearboxes. The metal construction helps with durability, and the belt drive is designed to be easy to remove when needed.
How much does the gear ratio affect crawling performance?
The 13:36 ratio provides a good balance between torque and speed. For rock crawling, this ratio helps deliver more rotational force to the wheels, which can improve climbing ability on steep or loose surfaces.
What color is the metal?
The gears are available in either black or red. The choice doesn't affect performance, so pick the one that matches your build.
