Leveling kit, does it affect MPGs??

[DannyMK2]

I did mine, no difference at all. Until I put on 35's. lol
But a level wont do anything.

its made a difference on the last 3 trucks ive put one one....

your altering the aerodynamics. its going to make a difference. maybe your driving patterns didn't yield much of a measurable difference, but for somebody else (especially somebody that does a significant amount of highway driving), it could/should be noticeable.

Yes it will affect it slightly. I went with motofab 3" front and 2" rear. I kept my stock 17s on my 2017 express quad cab. I lost about 1mpg. I still get 17.5-18
