New build.

How are the diffs in the new Emaxx's? Are they strong like 1/8 truggy diffs? I remember the version 1 diffs being super weak.

Don't know anything about the new 3905 EMaxx diffs. This thread is about a year old and it was about custom 3906 Maxx trucks. No stock 3905 diffs here.

The truck pictured has the RCM hybrid combo bulk/diff setup in the front and rear, and 1/8 HPI hardened steel diff gears set in RCM Savage aluminum diff cups, but the center diff IIRC has the Robinson Racing cup on it with hardened steel gears installed. That chassis is something RCsolutions made for a super extended Maxx truck. Harold gave it to me a while back. The truck is nearly done, but all of my R/C gear is still in shipment on its way here from our move from Asia to Praha. I probably won't really get to do much of anything with my R/C's for a few more months as we get settled in here. I still have to get everything moved in and put away when our household goods show up some time in mid May. Then I have to mount all of our audio and video gear as well.

The newer emaxx style diffs ( 3903/05/08 ) are something of an improvement over old 3906 diffs, but they are still fatally flawed. They still use only 4 spider gears, plastic diff cup and cases- put much power through them and the spider gears get shredded, as do the ring & pinion gears.

In future I would start a new thread in the T/E-maxx parts or General Discussion sections, rather than posting an unrelated question in an old dormant build thread.
