Dont drive it...biggest gas saver on a jeep.

There isnt much you can do to get better mileage out of your jeep...just take it easy on the gas pedal.

big tire size plus stock gearing equals worse than normal gas millage.. What size tires do you have? and do you have the right gearing for that tire size? is something you have to ask yourself.. Most stock TJ's get 14-16 mpg

Ya'll had it easy. They made us carry our Jeeps up hill both ways during wrestling practice, just to get in shape. Now I have the young men I coach do the same thing. I guess that is why they say; "Mens" wrestling is during "boys" basketball season. But, we all get great gas mileage, unless someone ate Taco Bell the night before.

get a primary vehicle other than a jeep if you're worried about mileage with your jeep no ways around it. you can spend all that money on a CAI, TBS, headers, & CAT back, but you're talking mucho $$$$ which isn't cost effective for the minimal mileage increase you're going to get, the engine really wasn't made for modifications, it was made for reliability. 31's really isn't a big enough tire to consider regearing, which is also a pretty expensive modification. is your transmission a manual or auto? if an auto, you're not gonna wanna go over 4.11s, with a manual 4.56's or 4.88s... you're probably seeing minimal changes in your engines fuel economy riding on 31s, if anything you're probably getting better gas mileage. its a battle that you can try to fight, but unfortunately you're gonna lose no matter what really... GL!

Want better gas milage? Buy a Prius. My 06 Rubi only gets 12 mpg average. I've come to accecpt that my loving Jeep has an unholy hunger for gas.

Yep that will work but if you offroad your jeep please be careful how much money you invest in the D35.. In the end no good can come of and investing into that axle.. Not to say people haven't gotten away with it.. But for the most part if you beat on it, It will go BOOM.. Especially if it's locked

Yea, the Dana 35 is a horrible axle. These are pictures from my first d35 I blew up running 3.07's with 31 doing mild trails and hills. I just blew up a second one and now i'm looking for a 97-02 non rubicon Dana 44. Or a ford 8.8 with brackets on it. I'm just sayin I wouldn't trust the Dana 35 for a second any more. Oh, and I think 456's and 488's r gonna b a little steep for 33's. You'd be doin 3k rpms at 65 lol you would b happy with 373's or 411 if u want the lower gearing

if you are looking for 8.8 with everything already installed check these guys out: Bolt In Axles - Complete Axle Assemblies - Axle Housings
This showed up in another thread I was reading, I forget who put it up so I will not take credit for the find.
