    I doubt the 1 inch wind deflector really helps anymore with fuel millage when the truck has a 6 in lift kit & big heavy tires. Those deflectors are use the cut back on the wind resistance under the truck right?

    Thanks! But take a look at ajarman's thread. He's got a Silverado and his pics give you a good idea of what yours would look like. I think it will change your opinion.

    I don't have the #s to confirm it since so much changed at the exact time I lifted, but I don't see how it could improve my mileage at this point.
