Yeah Racing TT02 oil filled gear differential

Yeah Racing have created this true oil filled gear differential for Tamiya’s TT02 and TT01. Using a design based on 1/10 competition touring car differentials to ensure smoother operation and with a proper seal, it comes with driveshaft blade protectors to protect the driveshafts and differential outdrives. This will only work with the small sized ball joint universals.
