I just installed the Peak Performance 1.25" top hat spacer to level my Overtrail. I think it turned out great and I am really happy with the results. I have leveled numerous trucks including my 4Runner, F250, F150 and Tacoma. I do not like the look, or performance, of raked truck - higher in the back then front. Vehicles come this way because manufacturers think they get better mileage. I have never seen an appreciable difference in mpg in any truck I have leveled, not lifted.
