TAMIYA 15434 Mini 4WD 3.7:1 Gear Ratio

● A set of gears, shafts, and round-hole ball bearings that can be set to a gear ratio (3.7:1) between the high-speed gear and the super-speed gear.
● Can be used for a wide range of Mini 4WDs, and if you are changing from the super-speed gear, all you need to do is replace the counter gear (green) in this set. Changes are easy.
● To change from a gear ratio other than the super-speed gear to 3.7:1, the spur gear built into the shaft must also be replaced with the spur gear (yellow) in this set.
