Most Popular Longview for 2021 GMC Sierra 1500

Perfect add on when you need it Why have those big towing mirrors block your vision when not towing. A must have.

Super easy installation in less than 60 seconds. Provides outstanding additional road coverage on both sides of my vehicle and camper, and allows me to see hundreds of feet to the side of my vehicle behind me.

Perfect fit.

Slipped right on my 2021 custom trail boss. Easy to install and remove. I’d previously bought some clip one off Amazon that were supposed to work but didn’t fit at all. I’m glad I found this place that knows what’s what.

Just installed them and tried. It would be great if they did not vibrate that much; unfortunately they do; so we will have to find a way to improve it.

Perfect fit ty.

Once the extenders are attached they work great but getting the passenger side on is a nightmare! Not sure why it's so difficult to get it on.

Arrived within a few days. It fit on my F150 perfectly.

Excellent fit and plenty of foam to protect the OEM mirrors. The only part I didn’t like was that the small mirrors, while adjustable, seems to slowly adjust after several hours of driving. Not dramatically, but enough they needed readjusted. Overall a great product for the price.

Fit perfect an only takes a few minutes to install. Very happy with purchase.

The product was exactly what I needed and wanted. Looks great on the new truck mirrows. The price was very reasonable. They work perfectly while towing our trailer.

These mirrors perfectly fit my 2019 RAM 1500 Limited. The slip on like a glove and are held in place by a simple hook device which you tighten. All features of the factory mirror are retained, include blind spot detection, camera, and folding mirror. I drove over 1,400 miles with these mirrors towing a 7' wide 22' travel trailer, I saw very little movement of the mounting sleeve and never had a problem with them vibrating. The driver side mirror worked extremely well to be able see vehicles behind the trailer, and could be easily adjusted to see the trailer wheel. The passenger side mirror is more difficult to work with because it is farther away from you and therefore appears at and shows a much smaller angle of vision. Unless you have an assistant, adjustment of the passenger side mirror is tedious and requires a lot of trips back and forth to the drivers seat. I've seen some reviews complain about the fit. I think they must have received the wrong mirror because they were perfect on my truck.
