[chadj1980]

I've got a spare obr 30.5.. I also was thinking of putting a pipe on it when it comes(vrc). will this buggy take the power or should I just put the 28.5 head kit on the stocker

I have a 28.5 in my 2x4 it,s plenty fore that.i think biger is better tho.i will covert it to 4x4 if they get the kitts in some time,i hope they get the complete gear set up also.
