I have only had them for a month. I think the quality of construction is very good. (We will see about the motors) I think there note to bad to install, but the directions are poorly written.

Not for someone without maintenance skills. These took a bit to get installed. I was able to get them installed by myself without having to jack-up the truck. Since I was doing all the work by myself it took me about 4 hours to get completely installed. Getting the wiring passed was the hardest bit to do by myself.

These are great and worth the money in my opinion.. the problem i had, was the instructions tells you to cut 7in off the board if your truck is a double/crew cab.. I did not cut them and they fit perfectly!!

Installed running boards, look nice but front wants to ride about an inch lower than the rear where the motors are at.

These look so much better than the giant factory steps that were on my Sierra. I was able to remove the old ones and install these in about 4 hours. Completely worth the extra cost for the Amp steps, very happy with this purchase so far.
