I am upgrading as I go, I installed the combo bulk in the front already. My rear diff is out now and I want to install the Hybrid bulk in the rear. I was doing a little reading up on it and it looks like with the 1/8 diff the gear ratio is different then stock. So there for I can not use the combo in the front and Hybrid in the rear. Is this correct?

Yes, the 1/8th scale diffs are a different ratio. You should probably just stick with the combo bulk for the rear too.

The Revo/Tmaxx diffs have a ratio of 2.846:1, and a typical 1/8th scale is 4.30:1.

I read the 1/8th diffs were 3.30:1
