I definitely should re-gear down to 5.13 with my 5 speed, but considering I have 230k on my 4.0 and I don't know what I'm going to do when it blows, I'm holding off for now. Jeep doesn't wheel all that often anyways. Put about 500 miles on it since last summer.
Oops! I didn't realize you had the 5 speed. I'm not as familiar with it so take my recommendation with a grain of salt.
