Dun get the center ball diff. I had one MIP but it slipped so badly even when I had it tightened all the way. The mini-lst is simply too heavy for the ball diff. So I used the spring washers from the ball diff kit on the stock plastic diff (spring washer mod from beatyourtruck). And it did held up under the brute power of a 380S 5100KV brushless motor on 3S. I took out the center diff to check it and it looked as good as new even after 10 runs. Slipper spur tightened to the point where the front wheels raise up slighly under full throttle. The stock center diff with the spring washer mod is better in transferring power to the wheels as it does not slip like a ball diff.
