Have had mine on for about 4 months now. Truck drives better, steers better, and mpg increased 1 to 1. 5 depending on driving conditions. Only complaint is that the black paint rusted through almost immediately. Also, you'll have to find a machine shop to cut holes in the plastic wheel center covers unless you want the lugs/nuts/and axles showing. Had a local mechanic do the install. He had to use a torch to heat the u-joints for removal. He was impressed with the quality and overall ease of installation. No regrets so far - a "must" if you plan to keep the truck several years and drive it 150K - 200k miles.
