Stock 3906 emaxx diffs = epic fail, quite often.

3.3spec diffs = better, but still weak

3905 diffs = much better.

Anyway, the hotbodies diff thing refers to 1/8 scale diffs- you can only use them with FLM Hybrid diffs/bulks, or UE Ultra Lite diff cases.

You could beef up your existing diffs with a metal cup, case and hardend ring gear, but you need to tell us which specific diffs you have now (model of emaxx?).

I would rather spend the money on FLM hybrids though, atleast that way you are removing the biggest weak link which is the spider gears- 4 spiders vs 6.
