yes, I had a 99 ranger XLT that I lowered 2 inches in the front and I saw about a 1-2 mpg increase on the hwy. of course, it did nothing for city driving except to make it much better handling.
by lowering it, your presenting a smaller frontal area. but I dont know how much of an effect it will have on a full sized truck.
