    Hi, Iím going to be doing the same and also have a MT,, any insights on how it performs off-road ?

    I can't speak on this manual tranny as I have an Automatic, but I have a JLUR with 37s and its awesome off road. So I must assume the MT is as good or better. I prefer the MTs, which I have driven for 40+ years of owning Jeeps, but my wanted to be able to drive the Jeep, so this is my 2nd Automatic Jeep.

Im looking to get the JLU Rubi in a manual transmission, I will be putting 37s and would like to know if this pulls as good as everyone says the automatic does? All I seem to find is info on the auto.

    Like others have said..see how you like the feel of the 4.10's and 37's. I went 5.13's for mine and it'll idle 2mph in 1st gear up a hill in traffic! Although 1st gear is officially a granny gear now lol. You'll be shifting before you even get close to crossing an intersection. I can let the clutch out without even tapping the gas in 1st starting off..its great.

    What's MPG like compared to the 4.10, I was going to go with 4.88 but I'm thinking maybe 5.13 is the ticket.

    I actually went from 3.45's and 35's to 5.13's and 37's so I can't compare those. I get about 15mpg mix of city/ highway. Recently did a 700 mile road trip and got around 16mpg..for a portion of the trip. Mpg will go up a bit once summer gas is back.
