I ran 37's with no lift for a while (jlRU). It would be fine for city driving. But, even with a RC 2.5" spacer lift, the rear tires rub the outside for the rear fenders when fully flexed (I have 1.5" wheel spacers and 37/12.5" tires, stock bump stop). If there was a fender kit that would remove the bottom half of the Rubicon fenders, add lighting, and increase clearance in the fenders, I'd be all over it.How much bump stop would you recommend to run 37’s stock? Would you have to use spacers if on stock wheel? Thinking of 37” ko2 on stock height.
