I have the 3.5 in rock krawler adventure series long arm lift on my 4dr Jk. I noticed on the drivers side upper control arm that the resonators O2 sensor is being hit when the drivers side front axle droops. The pictures below show the O2 sensor is definitely contacting the arm, but I do not see damage to the sensor, nor indications that the arm is fully moving past the sensor. With this being said, I’m curious if anyone knows of some exhausts that will cooperate with a long arm and give me the clearance needed when flexing. I have also noticed what sounds like an exhaust leak coming from the headers so I probably will be replacing the exhaust from headers all the way through to mitigate all forthcoming exhaust problems.
