What all would I need to do to my jku to run 37's with a 4" lift? I know I'll probly have to trim my fenders and use a programmer but what else? It's my daily driver on mild off road trips no black diamond stuff. I know I will need to gusset and sleeve my Dana 30 before I get crazy off road . Is it going to break or bend on road?

 

Sleeves gussets and youll probably want gears...and it can break on road depending onyour driving habits. ive seen things as simple as hitting curbs snap axles with 37s on a dana 30

 

That's what I'm afraid of Breakage on road!

 

You need to trim the pinch seam in the front of the rear fender well and if you have Rubicon rails they will need about 2.5" cut off the end.
