Tamiya 15355 JR PRO High Speed Gear Set - 4:1 Ratio MS Chassis Tune  [15355]

Summary of the Tamiya 15355 High Speed Gear Set

The Tamiya 15355 JR PRO High Speed Gear Set is aimed at Mini 4WD competitors who require stronger acceleration on MS chassis cars. The 4:1 gear ratio enhances responsiveness on sections with frequent turns and short straights.

Fitment Details and Performance Notes

This gear set is intended for the Mini 4WD PRO MS chassis only. Racers experiencing sluggish acceleration from the standard 3.5:1 set will find the 4:1 option provides a punchier response, particularly when matched with a high-rev motor such as the REV-Tuned.

Pack Contents and Practical Use

The kit supplies two G19 (blue) counter gears and two G20 (orange) spur gears. These are ideal for replacing tired gears or trialling setup changes without buying a new model. It offers a straightforward way to refine acceleration characteristics on race day.
