Okay, I know there are a million posts about gearing (and I think I've read them all) but here is another! I could really use some last minute advice before I get my Jeep regeared. I am currently running 33" takeoffs, and may go up to 34" tires (285/75/17) in the future when the current tires wear out. No plans of going any larger than that, as I want to stick with my current lift (2"OME, 1" BM and MM). I have the 4.0L, NSG370 6-Speed, and 3.73 gears in the Dana 30 and 44, and currently my LJ is way undergeared! I have had 4.56 and 4.88 gears recommended by others. The online charts / grimjeeper / forum members usually recommend 4.56, but I live in Colorado at over 9000', and spend most of my driving is in the mountains at high elevation. Most 4x4 shops in Colorado have recommended 4.88 (due to the altitude and hills). The Jeep is my DD, and I do 80% highway, 20% trail (no extreme rock crawling). I want to be able to go 65mph up mountain hills on the highway, and still be able to go 80mph down hills without revving crazy high. Medium weight Jeep (hard top in winter, might add steel winch bumper, etc). Any suggestions or personal experiences with similar set-ups would be greatly appreciated!
