Most Popular Pair of Mirrors for 2021 GMC Yukon XL

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

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.

Won’t stay locked in stoned position

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.

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

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!!!!

This mirror extension set was extremely easy to install on my Chevy Silverado. It looks good and seems like it will work well. I have my RV hooked up but haven’t tried them out on the highway. I will be watching for how secure they are at 70 mph. My only surprise was the design on the back side. I expected them to be just plain textured plastic. It’s ok though.

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.

It took awhile to get these mounted,the instructions were literally the size of postage stamps, black on black, like some smudges with a hand in front - useless so I figured it out myself. The clips that these were shipped with were on back wards to add confusion, I took the big plastic clips off and used the small metal clips, bent the clip so they'd stay on when the mirror was removed. I think they woud work better if the strap were closer to the two pads instead of to the single pad on the inside. They are interchangeable but the one on the right is adjusted differently than the left so I'll find a small way to mark them, they're a big enough pain to locate and clamp down enough to stay put that I won't want to remove them after every trip but if I don't someone will break on in a parking lot (without the trailer). I've seen molded morrors that fit specific vehicles, slide on, fit the factory mirror houseing perfectly and a clip around the edge by the window keeps it there - couldn't find one for my Subaru Ascent Premium so I'll use these unless and until I can find better.

I like these towing mirrors. They seem high quality and really help me see what is behind my trailer. I like the way they tighten down on the vehicle mirror. I wouldn't say they are a perfect fit for my Jeep Cherokee but they fit good enough. There is a little vibration but not enough to discourage me from using them.

Looks good, packaged well, no missing parts, but I haven’t installed yet. I knew ahead of time about the plastic hardware most everyone complains about, so I’ll order spares. Thanks for the speedy shipping

I purchased the Longview Towing Mirror set as extending mirrors were not available for my vehicle. They where easy to install, stayed tight and adjusted, and looked like they were part of my factory mirrors. I highly recommend them.

Fit well on the mirrors on my 2005 dodge ram, but to much vibration and unable to see when pulling down the road. However they were very helpful for backing up my trailer, which was the main reason I bought them.

Mirrors fit and look far better than others I had purchased. Easy to put on the truck, compared to others using straps and even then those aren't all that secure. These mirrors once put on properly don't move. So glad to finally get hold of a product that actual works like advertised.

They were delivered expeditiously, went right on as per the instructions and they are fully adjustable so I can now see both sides of the trailer when straight. It is a 8.5 foot wide enclosed car trailer. All good here.

not possible to bend the plastic enough to engage the threads without first starting them and then forcing the clip onto the mirror, then can only get about 3 threads to engage which I thing will strip out later. Maybe the plastic will mold somewhat over time with the sun and make it easier to engage. I am buying an extra set of the clamps just in case
