i don't have that setup myself but i do know plenty of people that do and it seems like the difference in mpg between 4.88 and 5.13 is very little. for me personally, i would prefer the extra power but if mpg is a real concern of yours, 4.88 is the correct match up for 35 and it will deliver stock like results.

They difference is very little and you will want the extra power with 35s. I ran 35s with 5.13s and now have changed to 37s and now want to regear to 5.38s. The MPG loss going from 35s to 37s was about 4 MPG because I am now under powered Go with 5.13s and you will be very happy.

How do the unlimited's with 35's and 4.88's do on the highway? Are you more limited on the top speed or comfortable cruising speed of 75-80 mph. Our interstate speed limits are 75 mph. Approximately what are the RPM's at 75 mph on a flat highway? I'm pretty new to the re-gearing process, so any help and advice along those lines is appreciated. I've still got the stock 3.73's and it's been somewhat bearable, but I don't think I'm going to want to go any lower than 4.88's, depending on the advice you all provide.
