Much More Diff Master
Korean company Much More have released their diff master, a tool which helps you rebuild the ball differential on your touring car. These smart tools have two functions, the first is a diff ring holder, with a small magnet on one side, so the diff ring can be attached and held easily for sanding smooth again. The other side of the tool can be used as a diff stand, securely holding the ball diff and stabilizing it while you insert the small diff balls and it also has a pin or a small block to hold the diff nut or screw, so you can reassemble the ball diff very easily. Available in 3 different versions for 3 different cars, the blue version is suitable for the Tamiya TRF416 & TA05, the purple version for the HB Cyclone and the black version for the Xray T2’008 & 009.
