2021 power retractable steps

[Soapmaker]

I see the 2021's are available with power retractable steps.

Does anyone have any info on how these steps mount and tie into the electrical system on a 2020? Opinions on whether to buy the gm steps or an aftermarket step such as the amps?

Id like to get them for mine but haven't checked with my dealer yet, not sure they will be available yet.  I think they are only available on GMC black diamond edition, not sure about Chevy.

I’ve got them on mine. They come on the black diamond or have to be ordered with the truck. If I were you I’d buy aftermarket. These wire into the BCM and seems like a pain to install. I’d venture to say that AMP probably makes the Oem ones.

According to the GM Online Ordering guide / site, there was a distribution update a few weeks ago that made this option (B3L) more widely available.  I was able to slide this option in to my AT4 order which just got picked up by GM this week.  I'm super happy as I was torn between the high-clearance step and the normal offering; however, I REALLY wanted the retractable only available on the Denali trim at the time.

could you do me a huge favor? can you measure the actual length of the board?

I am guessing Amp does indeed make them for GM, they look nearly identical. 

I think GM may be putting the longer board on them as opposed to what comes with the Amp kit.

I would be interested in swapping to the longer boards if they would fit.

thanks

I was wondering that too.  I'm assuming I'll be one of the first AT4s with the factory option.  Happy to take pictures/measurements when it arrives in the next few months.   Judging from your name, you must be a local!  (I'm in Canton)

You'll have to post pics and what you think of the boards after the truck arrives. 

 

North side off the lake....pretty much across from Cleveland.

I just picked-up my 2021 Denali and it doesn't have the power boards. AMP makes them and as I understand, the quality, fit and finish is excellent.  https://www.amp-research.com/powerstep-running-board/2021/gmc/sierra-2500-hd

i am guessing the difference between the 2 power step options for the AT4 and Denali are just the chrome strip on them. I know the Denali has it, I bet the AT4 does not

Had AMP steps on my 2015 Denali 1500 and no problems with them for 5 years. One of the first things I immediately did on the 2500 was ripping off the park benches and going AMP again.

It looks like the factory retractable steps are longer than the Amp steps when looking at pictures

they are. I asked another member to measure, he said they are about 90".

Amp has an 85" board. I may end up getting those. I don't understand why they come with the 79" boards if the longer ones fit

Want to sell originals?

[MMDenali13]

Sorry, sold them a few months ago.
