Ball Differential Set (MR-04)

Ball differentials have been a staple of RC racing for decades. It replaces the standard gear-type differential with a more precision differential that include hard steel “bearings” that are installed inside the spur gear. When driven at high speeds through a corner, a gear diff tends to lose drive to the inside wheel. This ball differential limits the amount of differential action, and allows to car to accelerate harder through high-speed turns.
