and you need the hagen widening right? And is the 300 usd shipped or not shipped. What year and model of yota cv's do you need? Did you have any troubles blowing stock sidekick cv's with the front locker before you switch to the yotas? im only running 31's maybe 32's soon and i don't do rocks, do you think this is really needed or should i just get the locker for the front, drive around, if i blow up a cv then buy the yota cv kit?
