T-Works 1/10th buggy ball differential tool
Made for many 1/10th scale off-road buggies is T-Works’ new ball differential tool that allows for easy adjustment of the often somewhat hidden units. The wrench features an angled tool tip that slides into the differential outdrive, reaching into the ball diff adjustment screw for convenient differential hardness adjustment without having to remove the driveshaft. The tool is usable for all ball diffs with industry-standard hex head screw and it is available from now on.
