Here's a question that I should know the answer to but, a brain fart is kicking in.
Will Ofna 1/8 diffs, specifically Hyper7 diff, fit in the Integy aluminum diff case?

what kind of bulks do you have? I doubt they fill fit.

Standard FLM..... Yeah I'm thinking they won't either.....Just can't remember for sure....Might just have to bite the bullet and go with UE diff cases

1/8 diffs will not fit in the stock diff case. The integy diff cases are the same as stock but metal instead of plastic.

You have 3 choices to convert to 1/8 diffs in the Maxx
1. UE Ultralight diff cases as you know
2. FLM hybrid bulkheads (it's a nice setup btw)
3. LST diffs with your bulkheads. Requires making an adapter ring to go between the bulkheads and diff case, hogging out the pinion collar for the larger diameter LST diff case and doing something about the larger 8mm diameter pinion (Traxxas is 6mm?) of the LST diffs.

And with any of these there's still the output side of the diffs. But that depends on what axles you're running. Plastic, cvd kit designed for stock diff outputs, UE cvd's etc.

Yup, knew all that , thanks for the effort though. Just couldn't for the life of me remember if the ofna's would fit in the Integy aluminum diff case. Have a set of the 8 spider Onfa diffs with nothing to put them in. Gonna have to order up a set of UE cases and they will be good to go.
