I have a set of Fox shocks that I just removed from my 2015 Silverado 4x4. I put them on within the last year and less than 5k miles. I traded the truck in so they are looking for a new home. The front shocks are mounted with the springs and the Fox upper mounts. It takes 5 bolts (and a small jack to push them up over the lower control arm) to swap them. No sprint compressor needed. They are also a coil over so you can adjust the front ride height. They come pre set to "level" the truck.
$850 OBO plus freight or local pick up in Central Ohio.
