Put the explorer brake kit on, its the same as the Grand Cherokee but with better bearings. I went with the 60 because there is a lot of misinformation about back bracing and other issues, the 60 doesn't need back braced, the brace goes over the top. Lots of offroad guys out there welding up the 60's tubes to the housing and not one average person needs to do multiple gear swaps like claimed that they need a 9" for. It would be down to money for me. Tim
