The front shocks are easy to install, but as any Chevy and GMC owner will tell you, the rear shocks suck. They're a lot thinner than OEM and honestly they're not worth buying. I have them on an 02 Yukon XL and the truck sits in the back so now I have to order a new set of shocks. I have a tool box and jack in the back, but even with the originals, he didn't sit down to spend a bit more for a good set. But the front certainly did its job
