Will a rancher turn 28″ mayhems

Ok so in a few weeks I’m going to buy a used rancher 420 sra 4×4 and I am going to be completely modding it out. One of the first things I am going to do is buy fronts 28x9x14 rears 28x11x14 mega mayhems on itp hurricanes. I was wondering if I will need to do any mods such as a clutch kit or gr?should I just go with 27"? i really want 14" rims but if I can’t pull the tires there isn’t a point. Gr are expensive and I’m wanting to stay clear of them if possible. Thanks
