But you have an auto, whole different world from a 6 speed.

yes i guess so because me and my budy had the same gearing wen we bought are jk s , we had 4:10 and he is manual and we had a diffence of 300 rpm at 60 mph ..

I have a 6 speed, 5.13's and 35's. At 70mph in 6th gear, I am at 3k rpms. I can accelerate up an overpass in 6th at 70. On 37's, I would think the 5.13's would be perfect, I will go to 37's next time I need tires. I think the 5.13's are a little deep for 35's. Just my opinion, but keep in mind I am in Texas, just outside Houston, it's pretty flat here.

With all the talk about strength, I would like to see a side by side comparison of the 4.88 and 5.13 to visually see the differences

Thanks for the input guys, pretty sure I'm going to stay with the 5.13's

i think in general 4.88 and 35s are the way to go. and 5.13 with 37s. But there are so many variables when talking about this topic such as enviornment, towing habbits, highway miles. Not an easy choice.

Thanks for the input guys. Geeper, In general from what I've seen there is a considerable difference between the auto and the manual. From what I've seen and read, 5.13 would probaly be a definate with an auto and if you were thinking of 37's since you have a rubi and dana 44's front and rear, then go 5.38's.

My opinion is to go with the 5.13 if you want to ever use your top gear
