I've only blown one diff, and that was from power launching it on pavement after I did my 2nd revo as a 3.3 (testing out wheeling, trying to stop it.) Otherwise diffs were ok, but I don't abuse my stuff FWIW.

The big thing I hated about the diffs was that they tended to leak and you about need epoxy to get any diff action out of them due to the 4 spider design. Where I have 5K oil in my 1/8 diffs, you need 30-50K in the Revo diffs to get the same action. For the C diff kit you need 500000 wt oil. At that point its not even oil, its sticky putty. Filling a diff w/ it sucks. Even at that it diff'd out badly. Then its major surgery to remove the diff. 1st time you do this and you'll know what I mean.

I just popped out the diff in my Savvy and it takes 3 mins. 6 ez to get to M4 screws and the front of the diff case just pops out. Don't have to touch hingepins or shocks at all. Same as an 'uggy basically. Then its normal wt oils to fill it and proper gaskets instead of those crappy rubber rings TRX has on theirs that tear way too ez and then can only get in a $5 parts pack w/ a new diff cup.

As far as suspension goes, part of it is that the Sav is just so much bigger (esp the XL I have.) Its taller and wider, and easily fits 40 series tires on it. You can run it higher and its not as dramatically tippy as lifting the Revo all the way up. Revo handles great on the middle or lower position, but not so great on the highest.
But also its also the difficulty of swapping around all that stuff to change the handling. You can put other rockers on (like LTs) but then you have to change the pushrods (and all that disassembly) and if you change the height you are supposed to change all the ball joints around for the bumpsteer. Ok, get out the manual, look up the setting, ok, tall hollow ball...where did I put it?.. pop it out the middle ball I had in there, save it..., put in the new one... rescrew everything back together.. oh don't forget the springs, take apart the shocks now... ad infinitum.

I changed around the ride height and the rockers once in 3yrs I had the Revos it was such a PITA. Screw it, just left the P2s and middle pushrod and kicked off the ruts I got stuck on. With a normal shock setup, you just move one maybe two screws to adj ride height and progressiveness.

Now I'm not trying to start a Revo vs Sav thread, or Revo sucks thread or whatever. Its still quite a good truck, and is a good all around truck that is a million times more durable than the Emaxxes (esp 1st additions.) I just got pissed at it for enough little things over the years that it just annoys me now. That and the half-assed chintzy TRX engineering. And all the nickel and diming TRX manages to engineer into them. (Death by a million little upgrades and option parts.)

However, if someone were looking to get a truck to go bash around the yard and never race with or try to set spd records with, I would highly rec the Sav over the Revo. None of this is aimed at you btw beatle, just an opinion on a general comment.
