I'm running my 08 jk on 285/65/18's with stock 3.21's and when i'm on the highway
i loose speed.What would be a good set of gears to run on that will maintain my speed.

The most popular is 4.88 with man trans and 35's. If you are even pondering going up to bigger tires I would suggest going to the 4.88. If you are really happy with the 33's then go with 4.56

Thanks for the tip and i do like my 33"s, it's just right for me .I found a gear ratio guide
on www.4wheelparts.com/aux_inc/gear_ratio.html based on 65 mph and a gear ratio of 1:1 on a manual trans in 4th.Maybe i could use this to find the right gears.Have a look at the site and tell my what you think.
