So I plan on getting the fabtech spindle lift for my truck this summer but I got a problem, my wheels are 16" with 4" backspacing. They recommend on a 15" wheel with 3 3/4 bs. I contacted fabtech to see if they would fit and they told me idk try it out -___- So does anyone out there have a similar set up? Should my wheels fit ok? The tires are 32" procomps that are 10.5" wide
