Ok, now i know upgrading gears will make spinning those big tires easier, therefore more power AND gas mileage.

Any testimonials on here for power and mpg's gained when you swapped???

I have 33's on stock 3.55 now i know thats ok but im looking for better mpgs as this is my DD... Will making a switch to 4.10's or 4.56's really help my mpgs?

 

Anybody? Lol

 

Did you change your speedo gear yet? Your speedo could be off more than 10% causing your MPG calculations to be way off... That is where I started instead of dropping a grand into gears...

 

Well theres a chart online i read and with my gears/tire size so my mph is like 3-5 more than what it reads

 

Than what its showing i mean

 

What should my mileage be around with 3.73 gears and 31s. I'm getting about 15 city and 18-21 hway. Will be running 33s come spring.

 

Ha I got stock gears and 265/75's and get about 220 miles per tank with a 3" lift. It's just terrible. If I didnt love the damn thing so much I'd get rid of it. Havent adjusted the speedo gear but with 31's I was only off about 2-3 mph which for every mile marker on the road I actually drove 8/10 of a mile on the odometer.

 

I have a 3.5 in lift mostly rubicon express but skyjacker shocks. It's more like 4 in the front but itll be around 5.5-6.5 come spring with 33s

 

Oh and my speedo hasn't been adjusted either, I'm about 3-5 mph slow

 

And my gears are stock jus got lucky with the tow package

 

any upgraded gears experiences is what im looking for...

 

Go to 4.10
