I am not sure about that, but with the 3" you probably got from the mopar lift you would probably be OK on road particularly if you pick a "smaller" 37 like the K02 or cooper at3 ltx that are 36.5 vs. a "true" 37 that is 36.8-37. Off-road I have no idea but I wouldn't want to do a ton of flexing without seeing what plastic molding needed to be removed or modified. I have 35" duratracs on mine and love them, will do a true 2" lift and think the spacing on all is perfect, plus will have tons of room for articulation.Could someone answer a question for me on the Borah Wheels please. Will I have any problems running the JL Borah or salta xr wheel (that have the same backspacing) with the Mopar 2 inch lift and 37' KO2s on a JLUR? Unfortunately I don't wheel much, so 90% on road driving. Thanks!
