I was an AMP electric steps guy until they screwed me. I had them on my 2106 Canyon for five years and then on my 2019 Ford Raptor. I bought the AMP's through an online sale and didn't keep the email. However, when they arrived, I filled out the warranty card and submitted it to them.
I had a motor go bad under warranty and called them. They asked if I had a receipt. I didn't. They chastised me for not having a receipt. I told them I had filled out and submitted the warranty card. They said they had an issue at the facility and lost all the warranty cards. Okay, I still have an issue and need a motor.....sorry you don't have a receipt. I asked hm to explain how it was any different that he had lost the warranty cards. He was just an ASS.
My neighbor also installed them on his 2016 Canyon. The motor just went bad on his......guess what, they discontinued the motor.
I'm sorry, I won't ever do business with them again.
My 2024 Sierra is a Denali and has the OEM electric boards. They have a nice feature, if you push the button on the end, the boards move rearward so you can stand on them and reach into the bed.
