I don't think a leveling kit will have much effect on you mpg....IF it did I would think it may SLIGHTLY increase by a point or two due to less drag from the front end.

Now...the tires are a different story. I would say probably atleast 1-2mpg loss (maybe more maybe less). You can always even that out by changing your gearing though to better match a larger tire.

maybe someone else can give you some more specific answers.

 

If you are asking a MPG question chances are you should not do this... That being said I can't imagine 31x10.50s changing your MPG much.

 

I've got 32x11x20 on mine with a 2" level kit and I get ~13-14mpg driving 85% city. Hope that helps!

35's when I wear these out, can't wait to see what that does to my mpg!

 

Yea I know another MPG question and I know you don't buy trucks for their MPG. But be honest everyone still thinks about it. So yes I am asking a MPG question.

Are you running the 5.4L ?

 

Yup

 

You will lose 1 mpg or so.

 

Anyone have pictures of our model 2.5" leveled on 31" 10.50 17 ??

 

Mine is 2.5" leveled on 32" by it's 10.50x20 instead of 17. Close, but maybe it's a good approximation?

 

Thanks. I am trying to figure out if 31s are going to look too small after the leveling kit.

 

I run 33's and sometimes they look small to me, I have flares too so I think it's exaggerated because of that. Check out my photos....
