Carson, I installed ems on my 12v and I opted for the large outer shafts and they bound up on hard right or left turn the solution was buy larger inner axles or grind the yokes down I chose to tac weld a 1/4" nut on each side at the stop surface. My intention is to buy the larger inner axles later and Steve has asured me that will resolve the binding issue , The 1/4" nut fix only cost me about a foot in my turning radious, only noticeable when doing tight parking manuvers. I am enjoying the increase in fuel mileage by 2 mpg. And that to me is well worth the investment . This conversion did increase wheel width by 1/2" on both sides which will help when I buy my next set of larger tires all in all I'm real happy with the results and the guys at ems are good to deal with I hope my expirence helps you with yours.
