Do the K-Source Custom Towing Mirrors Block the Cameras on a 2021 GMC Yukon?

Question:

Do the mirror extensions cover the cameras on the bottom of the mirrors? I have a 2021 Yukon.

No, they do not Jake. The K-Source Snap & Zap Custom Towing Mirrors item # KS49NQ are specially designed to not block the cameras, puddle lamps, or turn signals on your 2021 GMC Yukon. These mirrors have padded clamps that slide over and securely attach to your existing mirrors.

Please note that these mirrors do not fit extendable or telescoping factory mirrors.

What kind of trailer do you have?

I have a 14' enclosed aluminum car hauler. My 2021 Yukon blind spot adjusts when I'm hauling a trailer to "sense" for the whole trailer length; I use the cameras extensively for parking, so I don't want any interference with them. (I'm honestly not sure if the cameras are used for the "trailer length" blind spot warning.) I would have liked to see a picture of the towing mirror installed on a GMC with cameras showing the provision that allows the cameras to work, or just a bottom view of the towing mirror so that I could understand how it is not blocked.

@JakeK There's a cover at the bottom of the K-Source Snap & Zap Custom Towing Mirrors item # KS49NQ that you'll remove when installing these on your Yukon. I attached a video below we made on a 2022 Tahoe. If you skip ahead to the 2:15 mark you'll see the camera demonstrated. We also have a picture of the bottom of the mirror showing the cameras with the item # KS49NQ installed. That's as close as I can get to a 2021 Yukon.
