Best Center Diff yet? | ZD Racing truggy. | Warning: full run

I found a generic Center differential for my ZD Racing 9021-v3 1/8 scale RC truggy. This is compatible with Kyosho and Thunder Tiger RCs. I was skeptical at first regarding its plastic spur gear but ironically it is impressive. Best replacement yet!
