You say you tow with your jeep.
Get the 5.38s
You won't be happy towing with 5.13s

 

I have a 2011 jkur, 3.8l with a six speed trans. I have a 3.5" lift and toyo m/t 35x12.5x17. because of the tire size and running heavy due to bumpers, skid plates, winch, rock rails, recovery gear, etc. and not living in a flat part of the country, I went with 5.13 gears and am very happy with them.
