Have a 2006 Rubicon that was built (not by me) for off road. I'm wanting it to do some trail running, but also suitable for daily driving/road trips. It is currently running 5.13 differentials. I'm considering regearing to 4.56 or possibly even 4.27. It has 35 inch tires. I guess I'm asking which diff ratio would serve me best as both a trail runner (not rock crawler) and a highway driver? And I would lean a little more toward the highway driver in the consideration. Good on the highway, but capable on moderate off road trails.
