Most Popular Custom Fit 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.

Exactly what I needed for a better view behind my boat while towing it. Fits perfect over my 2021 GMC mirrors. Snaps on nice and snug. I was surprised to get a stowaway bag for them when not in use.

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.

Installed successfully on 2015 Chevrolet Silverado 2500HD, replacing factory mirrors that were power adjustable and heated - no turn signal. Motorized mirror adjustments worked fine. Haven't tested heated mirror yet. Since I did not previously have turn signals in my mirrors, the turn signals did not work on these as expected. May look into a way to make them work later, but no big deal. One improvement that could be made on these mirrors. The manufacturer is aware that the factory mirrors use 3 bolts, and these use 4. It would be nice if they would have included a nut for the 4th bolt, so I wouldn't have had to go search for one. One good thing, on my truck the hole was already there for the 4th bolt, so I didn't have to drill. Taking a trip tomorrow, so will see how they perform on the road. So far as what I have seen, I am happy with this purchase. I have used etrailer in the past and have always been happy with the products they offer.

Adjustable mirror fell out of mount on drivers side. Hanging by wires. Wind on highway blew mirror out.

They look good I know I will be able to see around my trailer. It took longer to install on my serra sle as I had to remove door panels. The passenger side drages bad extending and retracting.how about dry lube.

Mirrors work good. Very happy with them, online videos on installation helps especially with removing door trim pieces which for me was the majority of the time and difficulty. It plugged into existing wire harness and everything works like it did with OEM mirrors (able to control tilt using door buttons, etc.) I just wished they would have sent the nuts with washers like OEM. I used on the OEM original nuts since it had washer base on the 3 but had to go buy a washer for the 4th nut since the 3/8 hole almost allows nut to go through the hole.

Shipped on time and packaged well. Thanks!

So far happy with fit, install and initial quality. Product install video was helpful. Looking forward to towing travel trailer with these as the weather improves into spring.

I bought tow mirrors a year ago from etrailer.com and I couldn't ask for more they have held up very well and am pleased to recommend them.

We haven't used them yet while driving the RV, but the fit is perfect! Very happy with these extenders

Really loved my cipa mirrors on my Chevy. The dodge mirrors are tight if you use the right thickness wedge. Problem I have is that if your backing up and want to pan the factory mirror down for rocks or stumps the overhanging lip of the cipa mirror stopes the factory mirror. Will have to grind some off that lip for factory mirrors tilt up or down to clear for the tilt of factory mirror.

Buy these! You won't be disappointed! This is my second set of towing mirrors and I have to say that these are far superior to my previous set in the way that they "lock" in place and don't slip around. My only comment is that each mirror comes with a small plastic shim to make the locking possible. It would be nice if the mfg would come up with a way to make a storage cradle in each mirror for the part when not in use. Otherwise, it could be easy to lose which would make the mirrors pretty useless.

The mirrors were shipped and arrived extremely quickly. The directions for installation were straight forward and took all of 5 minutes to install. The mirrors fit my 2010 Silverado 1500 like a glove. I'm looking forward to putting them to plenty of good use in the months to come.

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.

Great people Fast Shipping

Flange on bottom prevents you from mounting mirrors in center. The mirror hangs below the bottom of the factory mirror assembly making it look very odd and out of place.

Great mirrors, I didnt have turn signals in my old mirrors but these work great, just plug and play

These are Quality Mirrors, very sturdy. Took me about an hour on the first side, (learning curve) but the second side was 1/2 of that. Makes the truck look great and can't believe what a difference they make for field of view. As for function my truck was set up for the turn signal and power mirrors and they work great.

Mirrors are fine. But, never used them not even one time. I put them on to see if they fit and took them off 5 minutes layer and put them back in the box. Reason, I sold the truck before I got to use them.

Only used twice as I found Tundra's stock mirrors were more than adequate for camper we were towing. I found mirrors were finicky to install without marring stock mirrors and never had a good feeling about security even though I never lost one at highway speeds.

Good mirrors for towing 28 ft travel trailer... Only got 3 star as first trip went we went to leave on thursday 5-25 for our first trip and went to put on and the passanger mirror was missing the screw to hold it on so i had to zip tie it on...on tuesday i will be calling to see about getting a replacement screw for next trip and will see how customer service is...

The towing mirrors are an exact fit. I was going to only use them when I towed my trailer but decided to keep them on permanently. They look Really good.

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.
