SumRevo is doing well. I have left the suspension LT rockers & inner hole. The drive shafts have no signs of damage to the u-joints. Again if I was ruuning a BL system I would be breaking drive shafts like crazy. Been there done that. I am going to put a 14.4 Dewat motor on it. I have the part's & have been working on it, when I have time. Have one for my Summit too.
