42197 TRF417 Gear Differential Unit II
The use of a gear differential unit is becoming a major trend at R/C touring car races around the world. This Gear Differential Unit uses oils with different viscosity for adjustment, which results in optimum power transmission from the high-power brushless motors as well as improved traction and acceleration. The unit is fully enclosed and the built-in gears are less likely to wear out compared with ball differentials.
