Tamiya 15456 JR AR Chassis Gear Ratio Set  [15456]

Overview - Tamiya 15456 JR setting gears for AR chassis

The Tamiya 15456 JR Setting Gear Set is intended for Mini 4WD hobbyists wanting to tweak AR chassis performance. A range of gear options helps you set up the car for varying track demands.

Chassis fitment and key features

This gear set is compatible with the AR, VS, Super-II, Super TZ, and Super TZ-X chassis families. The AR chassis in particular gains flexibility from the selectable ratios thanks to its front motor arrangement and aerodynamic layout.

Performance tuning and components

The set covers gear ratios from 3.5:1 to 5:1, letting you prioritise either acceleration or higher top speed. It also includes a fluorine-coated gear shaft and a 620 ball bearing to help reduce mechanical drag.

Installation pointers

Included parts such as the 1.4mm hollow lightweight propeller shaft and reinforced pinion and G-13 gears are designed for easy installation. That makes it straightforward to swap ratios during setup sessions or between races.
