I was at the dealer yesterday and my service writer mentioned that the 2012 JK's cause a problem with 3 inch lifts. They usually use a Teraflex lift on their new JK's and he said the exhaust system needs to be re-routed. Does anyone know if this is a common problem with all of the JK lifts or is it too early to tell?
I think it's mainly the full flex stuff that would interfer with the exhaust. I have a bds 3" on mine and have no problems. I'm not crawling, but hitting logging roads, creek beds. Around town stuff should be fine.
