I'm new to the forum. I read a bunch of gearing threads last night and still not sure what to get. I have an 08' 4 door sahara, 35" tall tires with 3.73 gears automatic. It is fine in the city, but cant stay in OD to save its life on the highway. Any offroading is not serious crawling and I live in Spring, TX it is flat as a pancake out here. I see alot of you are running 4.88-5.13. My question is, what gear should I get to run better on the highway. I was thinking 4.56-4.88. Any suggestions would be greatly appreciated.

 

I would recomend the 5.13's, but if you really want MPG then at minimum 4.88's dont do the 4.56 with 35's........ good luck.

 

My wife drives it everyday only about 15 miles round trip. I can't believe I would say this with gas prices the way the are, but MPG is not that important. Hell it gets about 12-13 right now. I was worried with 5.13 on the highway I would not be able to cruise that fast. Can you do 75mph with 5.13 with out it sounding like it is going to blow up?

 

Dont worry about highway cruising and 5.13's it not at all like a car would be with 5.13's I can do 80-85 no problem. You dont loose top end really, yeah you may not be able to do 125anymore . I think I am somewhere around 2700rpm at 80.
