Most Popular Slide-On Mirror for 2021 GMC Sierra 1500

I’ve had these towing mirrors for a year now and they work great for when towing my travel trailer. Very easy to put on and take off. Recommend this product for everyone.

Excellent product, very quick delivery, easy to install, the mirrors look like they came from the factory with the towing mirrors on my 2018 sierra 1/2 ton. Very happy customer.

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.

Mirrors fit well on my truck and did extend the view, however I have not used them while towing my camper yet but I think they will work fine and the cost is much better than the hundreds of $ to replace the mirrors on the truck.

Mirrors arrived ontime with no damage, they fit perfect & look great.

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.

Driver side mirror lock component "wedge" did not fit correctly , approx 1/2 " space between mirror and wedge ,was able to make accommodations. Passenger side fit well.

Shipped on time and packaged well. Thanks!

The product in theory works well. But, on an RV trip I found the mirror laying on the ground one morning after it fell off the product. Clearly the adhesive was not very good. The mirror luckily broke in half and I was able to get it back in place to complete my trip. I then ordered a replacement part for my GMC Sierra and was sent a replacement driver side mirror for a Dodge Ram (and yes, I did order a part for a GMC.) The customer service rep was very helpful. Ended up ordering a part off of [online vendor] since I could could only get it 3+ weeks with etrailer vs 2 days with [online vendor].

I love the look, the ease of install, and certain I would have liked the function. This model does not fit my 2020 raptor. If you have like model that does fit raptor, please let me know.

Most excellent product, replacing my drivers side tow mirror because a Wild Turkey flew out from the forest and literally straight into the mirror !!!! 20 pound bird at 50mph = no more mirror !!!! Caused door metal damage too... BUT the mirrors are the best designed, best looking and best performing mirrors, before a Wild Turkey hits it at 50mph...

Great product for the price. I ordered the pair for my 2016 Silverado. package arrived in good shape, no problems. Easy to install and fit as designed, nice appearance. Only glitch was the passenger side mirror had a minor defect in the reflective surface. Notified etrailer and was promptly taken care of - received a replacement mirror in short order with free return. Very impressed. The passenger mirror view is a little small for me but otherwise acceptable. I previously ordered / received a Curt trailer hitch with same satisfaction. Would definitely recommend this company.

Same thing

The mirrors help me tow our Lance trailer safely. The adjustable mirrors benefited with a touch of dry lubricant on the joint inside the housing. Emily at etrailer was very helpful!

First set had a factory defect. The hole for the tension knob was not threaded. Replacement sent was also a defect, the mirror panel swivel was un-adjustable. Spend the extra money and get the correct OEM ones for your vehicle.

Excellent Product…Easy to Install and the instructions were very easy to understand… These Mirrors fit perfectly on my 2016 Ram 2500 SuperCrew 4x4 Truck

So far this might do the trick . A bit concerned on stability after long trip .. we shall see in time !! The passenger side is not as tight as drivers .. again time will tell .

I guess you get what you pay for. They were easy to install on my Tahoe. The driver side works well as I can see behind my Travel trailer. The passenger side just doesn't work for me. Its a flat mirror (Not convex) so field of view is very limited, I just cant find the right position for it. I also find it a bit confusing as there are now 4 different mirrors to focus on. I think the ultimate solution are the larger telescoping units. But of course they cost more and installation is more involved. I don't trailer that much so I can live with these. Oh, one little annoying thing is they whistle when the window is down(Quiet when the windows are up). I think its the sharp edge. On the plus side removal is quick so when you don't need them they come off easily when not needed.

One of the best products I’ve bought in a long time. Fit perfect and was exactly as described!

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.

easy to use. works well.

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.

For the money, these work really well. My Tundra really needed these so I could see for lane changes with our 23’ travel trailer. I don’t notice any excessive vibration they makes it difficult to see. The only knock on them is making sure you get the insert lined up correctly when you’re putting them on. If it’s not lined up right they can work loose and fall off, but it’s as much operator error as it is design flaw.

2010 F150 Lining up the Thumb screw hole took a little work.. I did manage to get it all lined up With a little work and observation. I lined up the anti-slip plate with the thumb screw hole before I installed it, and marked The adjacent location with a sharpie. After realigning the thumb screw turned down all the way with little effect. Extension mirror looks sharp!! And is solid against the existing mirror.

Great product at a fair price and the best customer service on the planet! After having issues with UPS delivery resulting in them returning my shipment, Aris, the most fabulous customer service rep reached out as soon as they received it back at their facility and made sure my order went through to get these mirrors to me. She and everyone at etrailer are just great people to work with. My husband loves the mirrors, extended visibility, how easy they mount, stability, and they fold in! Highly recommend both the mirrors and the company! Thank you!!!!

they fit well, were easy to install and fair price

Clear image, do not shake too much, passenger side attachment bolt needs to be longer

I would like it to be extendable a bit further on the passenger side. The driver's side is fine though. The passenger side does not let one see far enough away from the side of the trailer. All in all, I like it better than drilling holes into the doors of my pickup to install huge mirrors. These look way better and are sufficient.

Proper fit, I have not trouble putting the mirrors on or off

Oh I like the mirrors, my only problem with them is that I wish either the hooks or the knobs were just a bit longer as they barely connect, but they do connect. Several years ago we ordered some mirrors for our van and they served us real well and I am sure these will as well. It isn't e-trailers fault, but the box arrived somewhat beat up. I have fitted the mirrors on our truck, but haven't had the chance to actually use them yet. 6 inches of rain has kinda kept us in the house.

One side does not stay adjusted and cannot see way to tighten. Was advertised as not blocking lights in mirror, not true as they are most certainly blocked.Otherwise good fitment and easy in install.

I received 2 orders now from Etrailer, one I did online and one soeaking with their agent and both arrived fast and as ordered! Great job very satisfied with product as well! Thank you!

As usual etrailer provided great service and prompt shipping. The product appears as described however I have not installed them.

Installation was very easy and secure. On test run there was no vibration angles remain constant for easy rearview examination

After a year of using these on my 2022 Ram 1500 while towing my travel trailer I have found nothing to complain about. They fit perfect, work as designed. Install and remove very easy with no damage to my mirrors and the power fold option still works perfect. Signal lights and puddle lights still work as designed with the mirrors on as well.

provides excellent views right and left side of trailer while towing. highly recommend!
