I have 305/70/17 and 4.88's with auto. If I was going to run 37's I would do the 5.13.

With a 3.8 auto I would agree with the rest of the folks who commented and say 5.13's for sure.

I changed my gears from 3.73 to 5.13 and all I can say is WOW! Planning on 37's in the future as well. I wouldn't think twice about doing it again.

I have the 3.8 and 35's and just got 5.13 gears and it is great, but I think if I was planning on 37's I would go with 5.38's. Just my opinion, of course.
