One of the questions that Cindy and I get asked all the time since installing a brand new EVO 2.5" Stage 4 Boost Lift and 37" Cooper STT Pros on our Jeep JL Wrangler Rubicon Unlimited is, do you have any rubbing? Being that we got our Coopers in a 13.50 width and have them mounted on KMC XD231 beadlock wheels that have 4.75" of back spacing, people have been wanting to know if they rub at a full turn, at a full stuff or at a full turn and stuff. In this episode of the JL JOURNAL, you'll get to see JET Li being taken out to do some flex testing, to find out where all his problem spots will be and what we did to help address them. We hope you find this video to be helpful in your JL build.
