Diff Buddy is your new best friend. A helping hand in a stand for 1/10 ball diffs of most off-road 2wd vehicles. The supporting blade in the stand recess keeps the diff screw up in the diff half while providing a stand for diff assembly. Fits stock and MIP puck style diff halves. If you need both hands and want a less chaotic diff to build this is what you're looking for. Feel free to sip your favorite beverage mid diff build without panic or excessive cursing. No longer will you have your diff balls flea like cockroaches as they bounce across the floor never to be seen again the night before race day.
