I measured my rear axles and they are 4" from pin to pin, thats with the control arms fully extended. The lower control arm (plastic part only) is 5" long. I hope that helps. I want to make sure there are no other parts I will need to buy. I would rather spend any extra money on converting my Tmaxx to the wider version. I am going to look on MIP and try and see exactly what you have and what the advantage of them are. I do have the new 3.3 motor on mine. But I have not had any problems with the axles. thanks.

I just looked on MIP website and it looks like I would need their kit #1485. This supposedly has both front and rear cvd's and associated parts. Could you look on their site and see if this kit is what you have. There should be approx. 12 pieces for front and rear, or 6 pieces if only front or rear. Let me know. I definitely have the narrow version of the TMaxx.
