Wow that's alot of mud. You are running the 2.5 Tmaxx converted? What other parts from the 2.5 do you still have on the truck? The revo 3.3 diffs won't hold up. And to be honest the 3.3 tranns won't hold up much longer either. It's a plastic gear tranns.. Even if you did the FOC. The Nitro truck parts/gears can't handle the power and tourqe. That the brushless motors can put out.. any way the diffs that you want to get are the revo brushless diffs.Or the Tmaxx 3.3 diffs.. but you should change the bulks to the grey ones from the tmaxx 3.3.. what axles are you running with?
Or if you can find the. The Emaxx diffs
