I have a 2018 Rubicon. It currently has a Rubicon Express 1.5/2.5 inch lift with adjustable control arms added and I am running on Toyo R/T 35's. I am wanting to go up to the 37's. Measurements indicate I got 2 inches of lift. Would I be able to to run 37's without any issues? I am asking because those who are running the Mopar 2 inch lift, are testifying they got closer to 3 to 3.5 inches of lift.
Teraflex has a pretty nice guide you can reference for their 2.5" kit. It will at least help you accurately figure out what you should need Bump wise to do it
