Does anyone have any pitures of 2-door JK's on 37's? I am running a 4" Rough Country lift with Smittybilt flat fenders and I think I could clear 37's. Also, what would I absolutely have to do to run 37's? I have an X model so Dana 30 in the front. I live in Florida, so there's really not a whole lot of places to go wheeling hard. Thanks in advance.

 

C-gussets for the front, trim the pinch seam in the front the rear wheel wells, and extend the bump stops as needed. You will probably need to shim your steering stops, too.

 

what is the backspace on the wheels?

 

Right now I am running stock wheels and tires. But when I go to 37's, the wheels need to have 4.5-4.75" backspacing per the lift kit instructions.

 

go even lower if possible. You'll be less likely to rub on your control arms

 

This may sound like a stupid question, but how do you know if you can go with a lower backspacing?

 

you can pretty much always go with lower backspacing because if will help with tire clearance on your frame or control arms, however when you go too low, it begins to put added stress on inner C's, stub shafts and unit bearings. I would not run anything less than 2.5" on stock axles, however you will never find wheels with that backspacing unless you go full custom

 

I was originally looking at the 17" Spyderlock's, and they only come with 3.5" backspacing. However, most of the other wheels that I like come with 4.5-4.75" backspacing. As previously said, the manufacturer of the lift's website (Rough Country), says the wheel backspacing should be between 4.5-4.75" backspacing.

 

3.5 will be perfect for 37's

 

Ok. Thank you for all your help.
