The only reason I got aluminum bulks is that the hinge pins would bend in a certain area ONLY because the bulks would allow it. With aluminum bulks, that area of the hinge pins NEVER bent. I ripped an RPM arm right out and the hinge pin was still straight as an arrow (though another part of it bent, which annoyed me).

However, my plan is to just run JDCarbon hinge pins...to run these, you just need to tap a set screw into the bulks (super easy if you run stock bulks, still not really that hard with aluminum bulks).

However, since these are CF, they will flex a little without breaking, helping to absorb impact. However, most importantly, they can't bend, so really you either break them or you don't. If you just keep a second set of them with you (they only cost like 16 for the whole set) then you will never have to worry...this is my plan if I get the new Maxx at least...

There is a heck of a lot of confusion over on the Traxxas forum, however, I have carefully studied the part numbers and exploded views so that I can provide a definative answer. The new emaxx diffs use different sized bearings on either side of the 'pumpkin', so they will not work with the older maxx style casings. The internals however will be a direct fit & upgrade to existing revo diffs. The entire new emaxx diff is a direct fit for the old emaxx and t-maxx bulks. Therefore, you cannot use the new emaxx diff internals with the flm combo bulks- only the entire diff with normal plastic/alloy bulks.

I find it amazing how even the traxxas employee over there wasnt aware of this at first, and still one or two kids over there want to argue the toss when the exploded views simply dont lie...
