All I have seen the lift kits don't do any justification in regards to tire clearance. You will still have to do frame mod. Have one friend did the lift and is having shaft problems !! Mechanics indicated is due to the shortness of the shafts. If its ground clearance you are looking for would go with larger tires. Bike has plenty power. I'm running 26's and have friends running 29.5 with no problems, as long as you don't turn all the way. If you need all your turning radius you will need to do frame mob. Their are many post indicating how.
