Best 2021 GMC Yukon XL Towing Mirrors

Need to test them out on a long trip, but so far so good. They did not rattle like the last set we tried. Hopefully they are sufficient one we get going down the freeway.

Purchased a different set from my RV Store only to find they did not fit my mirrors. Returned them the next day for a refund then ordered these from etrailer. Shipping was fast and delivery was quick. Installation on my 2020 Denali XL was ready and the mirrors fit perfectly. Adjustment was a snap and locked in with a screwdriver. The mirrors took a little getting used to but after a 15 hour road trip in two days I have become accustomed to them and absolutely love these mirrors. After arriving at our destination popped the mirrors off, put them in their storage case, and stored them in my RV ready for our return trip next week.

I use these on a 2001 Yukon for towing a camping trailer. The fit is so tight it is extremely difficult to install them. I let them warm up in the sun for a while first, that helps a little. Once installed they work as expected. (Taking them off is easy.)

Excellent product. Looks good, like factory equipment. Performs well, no vibration while underway, even at freeway speeds. The only problem I had was during installation. The mirrors came with 3 padded adhesive strips which either had to be removed or adjusted. It took me some time to determine where to place the strips or if they needed to be removed. Until the strips are properly placed, the mirror will not go on the vehicle. I ultimately ended up removing all of the strips for my vehicle. Even then, installation is tricky, but once they are on, the performance is great. Additional instructions that will guide you as to where to place the strips and when to remove them for different vehicles and features would be extremely helpful when getting the mirrors setup the first time.

Giving this a poor rating because I cannot get them to snap on. I yarned on them pretty good, until I thought I would break my mirrors, or these extensions. They are the exact part number for my vehicle. I read a review that said that they were "tough" to snap on unless they were warm. I'll leave them by the woodstove over night and try again tomorrow. I'm afraid that I will break them and not even be able to use them. If I can slam them on, I'll write another review. 2007 Yukon XL.

My order was delivered in just two days..The K-Source towing mirrors were easy to install on our '12 Yukon XL Denali and they look great!! Can't wait to try them out while pulling our 25' Airstream this summer. Thanks eTrailer..

Ordered the CIPA mirrors to replace some aging extensions I'd had for years. Glad to see technology & materials have advanced a ways since my last set. Fit perfectly & though I was skeptical as to the mounting system, they fit tight, no 'play' and secure at highway speed. A great alternative to the OEM, bolt-on extensions & for the money - far better than strap or velcro attachment systems. I won't have to replace these...

These fit my Yukon XL 2013 perfectly, were packed and shipped well and at a competitive price. They are snug fitting but it is a good idea to clean and wax the existing mirror housing to avoid scratching the housing as these are put onto them. I'm glad the instructions told me to do that.

Product came out of the box ready to install. Installed on 05 GMC Yukon XL and fit (for the most part) the way that I thought. Little extra space at the top of the mirror but other than that everything seems to be good.

I got exactly what I thought I was getting, a lot faster than I thought I would get it.

Got our mirrors yesterday and they were exactly what I wanted. I was impressed with the fast delivery on my order. I would definitely recommend Etrailer to anyone.

I had a set of these for 12 years and they worked great. I lost them overthe winter so reordered them and could not be happier having them agaon. Easy to put on and take off and easy to adjust

I bought both sides for my 2011 silverado and they look really good they look like they are factory mirrors install very quickly about 1 minute a side and they still allow the mirror to fold in if need be and they don't hit the side of the truck when folded in they fit my needs just fine the only complaint I have is the mirror itself could be bigger its about 1/3 the size of my factory mirror you have a decent blind spot when using them you just have to check yourself and its not a problem other than that they fit my needs well and come on and off quickly so they work really well if you don't tow 247 but it you tow very often like for a living I would recommend the full replacement ones cause they have less blindspot but if you tow every now and then they will suit your needs just fine I would recommend this product it you tow every now and then

Service and product review. Everything began with the virtual storefront providing a comprehensive review of the product and a competitive price. I could not find a brick and mortar dealer for this product in my area with such a minimal lead time. $450 for a set of OEM tow mirrors was not in the budget I purchased two towing mirrors for my 1500 Silverado. One was out of stock in the warehouse, but a customer service rep called me to tell me it would still ship and arrive the same day, just not in the same package from etrailer. This simple act gained my confidence in etrailer to recommend them others. The products purchased installed simply and quickly. Great Job!

Replacement for old strap style mirrors. Fits snug and does not move around in wind.

I bought the towing mirror to replace one that got damaged. I like the mirror and was pleased that I found the replacement at etrailer.com. The site was easy to use and the order was quickly filled.

Fit & appearance is OK. But the upper mirror (the controllable portion) wobbles enough to be bothersome. It catches my peripheral vision and distracts me. Moreover the shaking makes it’s difficult to identify vehicles in view. As a result, I primarily use the bottom mirror and try to ignore the upper. One thing I had to get used to was being a little wider than before but I don’t mind. Once I get time, I will try another brand & see if they are better. Nothing here is a reflection on etrailer, which I have found to be good to deal with and believe they have products better than some other websites.

Easy install, factory look, and stable when extended. Great visibility. 2006 Yukon XL.

Love these mirrors! Have had them on the truck now for a year and they work perfect and give you a lot more visibility than the standard short factory mirrors. No need for aftermarket extensions with these. Plus they slide out if you need even more visibility but we never had to use that alternative yet cause they work great just the way they are. We tow a tandem axel 7x14 cargo trailer and have plenty of visibility to see backing up and nicely down each side while driving. Much safer in heavy traffic. Installation was very simple and the mirrors bolted right on with exacting fit. I would totally recommend these if your needing better visibility over the small OEM mirrors for towing or just daily driving.

Love the new mirrors they are just what I needed. I previously purchased mirrors that would install over the existing mirrors when towing large and/or long loads. However, these new are much better and always available - just pull out for large and/or long loads. Also, the new mirrors were very easy to install; and, again I cannot says to often that the fit certification and installation instructions from Etrailer are right on always. Finally, if you have anyone who would like to have my previous mirrors that were purchased from Etrailer let me know.

Replacement for old strap style mirrors. Fits snug and does not move around in wind.

Exceeded expectations as a add on to the factory mirrors for both a Chevy Silverado truck and a Ford F150. It appears the extension is a perfect match and functional solution for trailer towing without the expenditure of new mirrors. Etrailer was not only the greatest value for this product from any internet site or regional store supply, but they also beat their date of delivery by six days on a UPS business delivery. I will definetly use etrailer for future purchases!!

I'm very happy with these. The video made install a snap. I installed on a 2010 Silverado 1500. I did not have turn signals in the mirrors before, but I do now! These mirrors fit great, work exactly as advertised, and are worth the price.

Have held up well after more than a year of use. I feel safer towing and parking with these over the oem and other mirrors I have used

Have used these on our 2015 Yukon XL Denali. They fit and tighten very well and are easy to install. I have them set up as shown in the picture here (horizontal). You can also set them up in the vertical position and I tried that but I lost peripheral view and like them better horizontal. Once tightened correctly they are very stable with no vibration. The material that comes into contact with the backside of the vehicle mirror is all rubber and there is no fear of scratching or damaging paint. I did turn off the feature that turns the mirrors down when in reverse and I don't fold in my mirrors when these are attached.

Product arrived sooner than anticipated. Great product, much better quality than I expected. Have owned other Mirror extensions but these are top of the line; especially the holding mechanism. Always use etrailer...great organization with above average customer service.

The Product does not allow both clips to fasten on the bottom due to the design of the car mirror otherwise holds fine and works.

I chose not to go with power mirrors. I'm glad I bought these, the fit is perfect, and the lower mirrors are fantastic to see cars in your blind spot even when not extended for towing. Very happy with my purchase. 2002 avalanche

I love my mirrors thanks etrailer they was simple to put in no hassle at all

This was the longest hitch ball mount I could find anywhere. I used it with a short extension for my 2021 T G so that I could open the back doors without hitting the trailer wheel crank. With my new trailer, Intact Flyer Discover, I don't need the extension and can still open the doors. Works well.

Very good quality, excellent fit, easy to install. So nice to have flat mirror on the passenger side for backing my trailers. Highly recommend these mirrors.

Very good quality construction. Very good fit for a non-custom mount. Thick rubber straps are stretched over the car’s side mirror and hold the mirror well. My car is a 2017 Ford Expedition EL. Note: when you fold in the car mirror the towing mirror partially blocks the progress so that mirror stops early. It is still folded but not as completely as without the tow mirror. And yes, they are two identical mirrors so on one side the straps go up, on the other side they go down.

BUYER BEWARE!!!!!! I had great hopes for these mirrors. They look great. They appear to be very adjustable right out package. They fit on my Tacoma securely. They don't interfere with the function of the stock mirrors. Everything was moving along "swimmingly". Then I sit inside my truck to do the final adjustment (moving the actual mirror to get the correct setting and lock it into the "sweet spot"). The new Mirror is very stiff...doesn't want to move. Well, its new...so....Okay, I don't want to ruin anything...so.... No worries, I go get a phillips screwdriver to loosen the back screw a smidge so the friction adjustment can work . Come back start to back the screw out just a smidge...nope...still can't adjust the...wait...unscrew some more....that's not an adjustment screw at all. That just screws directly into the back of the mirror to hold it solidly in place. Worse yet, There is no friction mechanism on the back of the mirror at all. It is one solid piece of plastic. The molded plastic replicates the look as if it has the ability to move, but in reality....There is no way to do small mirror corrections once you have this thing installed. What the Actual people?????!!!!!!???? If you can't do minor adjustments to the mirror while you are in the vehicle, then the mirror is completely useless. I wouldn't recommend this product to my worst enemy. It's a piece of crap. DO NOT BUY!!!! A complete waste of time, money, and shipping costs. Now, I have to incur more shipping costs to send this POS back to etrailer. Hey, etrailer....Do Better next time!!!!
