The Tamiya 53117 RD 0.4 Steel Pinion Gear Set suits hobbyists looking to refresh or upgrade their 1/10 on-road drivetrains. The set features two steel pinions, one 26T and one 27T, built to withstand repeated running.
These pinions are formed to work with 0.4 module spur gears, giving smooth power transfer and consistent mesh. The hardened steel construction increases resistance to wear compared with softer materials.
Alongside the two pinions you get the needed fitting tools: a hex wrench and three grub screws so you can mount the pinions securely and get back on the road quickly.
