Leveling kit for Powerboost - best recommendations?

[TravisM]

Hello friends,

does anyone have any input on if I were to get a leveling kit for my powerboost, which kind? Does it impact the fuel mileage? Etc. looking to level and put 34s35s on it but wanted to know if it’ll kill the fuel mileage like it did on my 5.0

I've read that the 2" level will negatively affect the MPG's about .4 MPG's. 34's or 35's will also negatively affect MPG's and if you get the heaver LT's then it will go down even further. I haven't done anything to my PB yet as far as level or tires since I still have my 19 EB that is levelled on LT 34's and gets 15.1 MPG's. The stock Hancook tires on my PB are 33's so I was just going to do a 2" level and get a more aggressive tire that is the same size as stock and NOT a heavier LT and use the stock wheels. The stock tires weigh about 41 lbs. each vs an LT tire which is 60+ lbs. each. I've been able to maintain 23.5 MPG's for the most part with the PB.
