2.5 lift questions

[CamoFreak117]

Ok so I have a few questions. I hear that under the Ford warrenty you can only have a lift no more than 2.5 inches. Is this true? My other question is how bad will my gas milage suffer with a lift kit and AT tire?

Idk how much lift but when I did mine they said it would mess up any suspension warranty that was it same dual exhaust just messed up the exhaust part

Yes it will void it and I know a 2.5 lift and a set of 35 Mickey Thompson bajas took about 8 miles off my mpg until I bought a edge programmer and it went back to about 15 city 20 hwy

I don't like that lift it's made my truck ride like a one ton truck

I put 18" Goodyear Wranglers on my 05 from 17" street tires and my mileage went down a good 1 to 1 1/2 mpg if that helps any
