    Exclamation Diff between e-revo and e-maxx confirmation

    Hi guys I wanted just to have a confirmation .
    The difference between the e-revo and e-maxx diffs are just the diff housing?
    After carefully looking at the exploded veiws of both I saw that all the components are the same and set out exactly the same.
    Could everyone who had use the e-revo and e-maxx confirm
    The housing for the e-revo is 5380 and for the e-revo it is 3979.
    Thanks

    The internals are the same but the outer case is different. Same goes for the nitro versions.

    and the difference between nitro and electric is that electric has the "I bar" in the diff for more support.

    Do the nitro models have the I-bar?

    Correct. I should have ended my query with "now?"

    Awesome , thanks guys
    The reason I asked is because it works out cheaper for me to buy an e-maxx diff and add 5380 diff housing for my two parallel projects.
    A normal e-revo build and my hybrid build.
    Have a great weekend every one

    Last question will the nitro diff be able to handle brush-less system
    I have purchased the parts to build two diffs, but unfortunately they offered me the 5381 diff carrier instead of the 3978.
    Got home and I found that they are exactly the same except that the 5381 does not have the I bars...I put this question in my e-revo build.
    If you could answer there it would be awesome
    Thanks

    From what I read, the I bar is required to have the diff strong enough to take the power of a brushless system. Nitro has no where near the instantaneous torque of a brushless motor... especially when it is fed LiPo!
    Whatever it is I just said... I could be wrong.

    Yeah I did find the 5382x whcih is suppose to have the I bar, but it is the cup carrier that I have to change, mine 5381 does not have the 3978 extra parts that come with it. Will go back to the lhs next week to exchange when the 3978 comes in. This is the illustrated diagrams

    The nitro version will not be able to handle the brushless power; to my knowledge it is still the original design. The I-beam in the electric ones provide additional support so that the pin holding the spider gears do not carve their way into the cup. I noted this was happening with my 3.3 Revo so I stepped up to the e-version of the diffs years ago with no further damage. The cups are different between the two so you'll need the e-version.
