Do the 2.5" leveling kits hurt MPG's that badd??
 

Just wondering if leveling kits can hurt gas mpg's that much by taking the "rake" away from the factory strut setup???

I think there may be an aerodynamic factor, but usually it's the larger tires that get put on after the leveling kit that do the mileage damage.

anyone else have input???

Agreed... Had my 295/70/17 before my Level and once level was on, very little to no difference.:D

I added a 2.5 and 305 20's and noticed little to no difference.

The leveling kit really will not do anything to your mileage. I ran my 2.5" kit for a year with no other mods. I did not notice any difference. Once I put on my 33's? Then that is another story!

Agreed.

Like many have already stated.

A level kit on its own will do [almost] nothing to your MPG.

But rarely, if at all ever, will someone level their trucks without the addition of a wheel and/or tire combo.

That's when the MPG numbers may change significantly.... dependent almost entirely on what wheel/tire package you so desire.

Agreed

It's the tires that kill ya!

I have a 2017 Lariat with 3.5liter,355 rear gears,scab,etc.FX4,7000# GVWR package
Was wondering about lowering the rear,to look level with front.
wondering about pinion angle changes,rear shocks bottoming out....etc and gas mileage,using stock wheel/tires = 275/55R-20 BSW All-Terrain[factory wheel+tire for Lariat special edition
I would like the truck level,but not at the expense of ride,handling,fuel mileage .....
thank you
