I meant they didn't change the suspension on the Revo when they put the 3.3 into it.

Just out of curiosity, what suspension changes did Traxxas make on the 3.3 T-Maxx? I work at a LHS, so this is some good info. to know. (We only have a 2.5 T-Maxx on display, so there isn't a 3.3 for me to look at.)

Only thing different is the colour of the shocks and the arms are slightly different to use the revo shafts. (they are notched)

the revo shafts have become updated to match the bulks of the maxx (they have got an X behind their partnumber now)

and it uses revo knuckles. as well as other turnbuckles. that's about it.

it uses different differential cases, 4 screws instead of 2, and grey updated bulks (not only changed the colour, but also a slightly different design)

The turnbuckles look fatter to me as well. I had some pics around here.
I could find them and send them to you if you like.
