here is a pic of the traxxas on w/ gear...


here is another question, ae all diff cups bolt pattern the same......does anyone have any info on this....

If traxxas will sell the gear seperately we may have a winner. I would just mod the adapter that I am having made to bolt to this gear. Hopefully they sell it seperately, as they do with the revo center diff:

No problem, the more ideas I here the better the finished product will be! I am glad you posted a pic of the erevo center diff, now I can see what it looks like. Where did you find the pic?

Don't maximizer's work with emaxx old style diff's? So the question here would then be, how can you get the proper internal's?

The maximizer cup uses std traxxas internals, so 2 spiders and 2 output gears. I will see if I can get my hands on a center diff kit, and try to use the gear on my adapter. I have a revo center diff, wrong number of teeth, 29 vs 33, but it should be the same size...

By 6 spider, you mean 4 spider gears and 2 output gears? A six spider diff is like the ofna spyder diff, and the ue diffs. A 4 spider gear diff is like a std 1/8 buggy/truggy diff.

Yeah, but is the cup the same diameter as the maximizer? Looking for something that can hold a 6 internal, yet bolt up to that gear.

I doubt that you will find that. Looks like traxxas uses the gear on the center diff as the cover.

When cowbody made the setup for the nitro revo he used a different gear, as he had it machined to mount to an adapter that acted as the diff cover.

My main issue with the traxxas design is that it uses the output shafts to hold the assembly up via the stock bearings. I plan to have the diff case and my adapter run on bearings, and the shafts will run inside the diff and the adapter, just like they do on an 1/8 scale diff. Should last longer and rotate true. Plus my design will have a 4 spider diff, not the 2 spider traxxas setup.
