I have a 06 2wd Ranger Sport. I was wondering if put a 3" spindle lift on my truck can i still use my 15x8 Crager soft 8's (4inch backspace)?. They recommend to use a 17" wheel or larger but Fabtech told me that i can run those rims still. Im just trying to get extra for sure. And when i put that 3" spindle lift on do i have to replace any stock suspension parts?
