Installed on my 2005 Chevy 1500 Z71 because I needed a little more cargo capacity for towing and towing. Great product, good quality and pretty easy to install if you have some basic mechanical skills. I installed in my garage using jack stands and a jack in 2.5 hours. If you have an elevator, maybe cut that time in half. Would definitely buy again, arrived in a day or 2 and would definitely recommend.
