Nice Look
Really like the look of my silverado with this kit installed. Good value and quality seem above average. Instructions where clear, took about 8 hours to install. Did a little trimming and was able to fit 35 inch tire / wheel combo. Happy with purchase.

Good Product
Looks great on the Truck, messes up the ride, it is much stiffer and you feel every bump through the steering wheel. Looks much better than the other lifts because you don't have all that hardware hanging down and is not permanent so it will allow for better resell. Running 35's now with no cutting or rubbing. Installation, took about five hours in my buddies shop, could not imagine trying to install in my drive way with a jack and laying on my back. Over all very happy
