Ok.
So we have mixed opinions regarding mpg and gear ratio.
Up or down.
Hmmm.
I did 75-80 from Henderson to Houston today, and got 13.8mpg.
Stock gears still, with 36s on 20s.
Haven't struggled offroad much, but wonder what I'm missing.
Not sure I'll ever figure out regearing. Everyone says something different.

 

As I said in my post above:

That's no B.S. Regearing helped make the warranty case.

That said, each dealer is different.

 

Damn, i dont think that would work with the ass hats that run the service dept where i got mine.

Your original statement was, "NO. Depending on what gears you get the worse the millage. Gears just give you stock engine and execration performance, not gas millage. the higher the gear the worse themillage, 3.21, good, 5.38's very bad. so 4.88's will get better MPG than 5.13's, but worse than 4.10 and 3.73 will get better MPG's than 4.10's. So no matter what, you will loose MPG, just how many is up to your gearing."

The higher gear numerically will not necessary decrease your mileage. In my case it didn't seem to. I say didn't seem to, because even if I remove all other variables I still cannot say how much affect the height difference or increased accessory weight has on my mileage. However, I can say that the difference between stock 32" tires with 4.10 gears is comparable to 35" tires with 5.13 gears.

In my case, 4.88s might have given me better mileage than 5.13s, but I'm guessing that statement would be invalid if I were running 37" or greater tires.

Sorry, I'm not trying to poke at you. I just don't see anything accurate with your original post.

 

I tend to agree with JPop's statement. I can't say I get better mileage, but no worse by keeping my RPM close to the 2000 range when driving 45-50 MPH (which I do often). I have auto, 3.73, 32" stock tires. I keep the OD off even up to 55 MPH and in relatively flat territory I do not see more fuel consumption. As for hilly terain, I can't say but it wouldn't matter then cause OD off would be manditory in my opinion. To me, the stock JK does not have good driveability until 60 MPH and above in OD.

 

I have always lost mpg when regearing different vehiclesincluding jeeps.

 

quick quest. guys. In my case with 3.73 gears now and 33" tires, and an auto tranny, would 4.11 be the best gears fo me? Or should I be looking at another set of gears.

 

I have 5.13s on my auto to spin my 35s and it gives the jeep the extra go and low gearing a jeep should have IMO. If I was you and going to regear for 33s I would likely go 4.88. I would definantly go no less than 4.56. Do you plan to stay on 33s forever? if you are going to 35s I would maybe wait and go 5.13s then. If you went 4.88 now though, that would give you awesome low end power and better in town MPG, then if you went to 35s you would have close to stock rubicon gearing.

 

Well guys, I will report my results when I regear! Sadly though, I don't know when I'm going to, money has to catch up!

I have alot of added weight, but the only thing that changed just now was the lift/tires, all the weight from my bumpers/winch/snorkel/skidplates/gear was already there.

So, when I regear to 4.88, I'll see the change for a modded 2-Dr and report the results so everyone can hear.


One more pic as I love my Jeep...

 

I've got 37" tires and I'm getting about 10mpg on the highway.

If I re-grear what would I be looking at?

Also how much it generally cost?
