Being that you have a 13' and a manual tranny 4.88 might be better for 37's
So I just had 5.13 gears installed in my '07 JKU with auto and 35" tires. I was going to originally get 4.88s but was talked into 5.13 by trail jeeps and others that were running them with no issues. The shop that installed the gears in my rear 44 said he hates putting them in because they get too hot and don't last. Anyone have issues with 5.13s in Dana/pro rock 44 with 35-37" tires? I'm worried I should have stuck to my guns and got 4.88
What cozdude said ^^^
With a 3.6L motor and a manual transmission, 4.88's will make your 37's feel like you're stock again. 5.13's aren't a bad choice as they will give you a bit more power but you will be running slightly higher in the RPM at highway speeds.
Thanks for the input, I left my order the same with 4.88s. I was about to get it change when I stumbled on this thread.
