Iv'e been running the Kraton front cvd's on the back end of my Kraton,bolt on with no clearance problems.They have been holding up great and still zero wear on the diff out drives.I had heat hardened the diff out drives to see if they have less wear and after 8 hrs of run time with a 4092/1730 motor i can say it was a success!Some Kratons may not have enough clearance to run cvd's in back,install one and move the suspension around spining the wheel to make sure there is no binding!
