Most Popular Fits Driver and Passenger Side for 2020 GMC Sierra 2500

Nice well built product with easy installation.

After a purchase of a Fifth Wheel RV, we knew we needed extended mirrors. The price of towing mirrors from the dealership was too expensive. We found these custom fit mirrors and they fit perfect, and the extra side vision is just what we needed. Thank you for a wonderful product.

On my old truck I used the CIPA slip-on mirrors. They we always a pain to install and adjust. These new Longview mirrors are great! They are easier to install, and seem much more secure. The mirror surface area is larger than the CIPAs, and the adjustment is smooth and positive. My only critique (otherwise Excellent) would be the large funky flaming bird embossed on the face. This needless decoration seems more suited to a "boy-racer" product than a towing mirror that will probably be sold to more older citizens than young hot rodders.

I haven't tried the product out because I haven't bought a trailer yet but the installation was easy and appears to give me the added depth of vision for a trailer.

just got my new tow mirrors. very good quality, I was going to wait until morning to install them but I could not stand it. It took me all of 15 min. to do the first one and about 10 min. on the next . Going on a 900 mile round trip this week end . The quality of the glass and adjustability is great . thank you for another great product.

Product looks great and fit on perfectly

Arrived as scheduled and the packaging was very good. The mirrors are very sturdy and don't vibrate at all. Installation time wad about one hour but I have had some experience in removing the inner door parts. I do think if you do not have any experience with them the installation will be longer. Everything works great and advertised and again etrailer.com comes through.

Received my mirrors in excellent condition. Installed them in an hour and a half. Very detailed instruction sheet.

Like these much better than previous trailer mirrors I have used. One piece design is nice.

Outstanding fit! Loved them right off the bat. No vibration and I think these were a good buy.

After recently purchasing a travel trailer my wife and I knew we needed to upgrade our stock truck mirrors to trailering mirrors. I searched many websites for the right set of mirrors. Etrailer.com hit the mark. Not only did they have the extendable mirrors we were seeking, they also had a price within our budget. These mirrors come as a set. They filled my order promptly and the package arrived in a couple of days. The installation for both mirrors took only 2 hours. They function well and look great!

great mirrors

Mirrors function as represented. The only concern is that the blind side detection system is "hyper-sensitive" and activates the warning by way of an LED display in the main mirror. This occurs even when there is no vehicle present but when you come within range of vegetation along road shoulders. This function is a bit distracting. Is there a way to adjust the detection camera?

Look great fit well and should work well for towing blind spot sensor works well maybe too well

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.

As advertised fit was very good, worked as should would recommend these mirrors, will be used to see pulling a camper, and etrailer to purchase from. 2014 Silverado 1500 LTZ four door crew cab standard bed.

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.

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.

These mirrors are great quality very close to OEM . The installation went very well. I did take the door panel off to make it easier to get to the two lower fasteners, just to make sure I didn't loose the nuts inside door. There was very little vibration in the mirrors, I was a little worried about that by reading previous reviews. The mirrors held their positions, folded nicely when parked in tight spots. Everything said this is a great quality product

Great customer service! Free and fast shipping. The glass on the mirrors shake when your on the highway. I don't know of it's all towing mirrors or just these. Easy to install an fit perfect. Overall I'm happy with the product. Thanks e trailer for the great customer service.

The extension mirrors are of excellent quality and fit my truck very well.

Fit well takes seconds to install

These worked great on my wife's Yukon. Installation instructions were clear and direct. They held up very well traveling 75 mph down the interstate; No jostling around or coming loose. I loved the additional two mirrors. Having the three total different angles while pulling a trailer was extremely helpful. Would highly recommend this setup.

Tried 3 other styles of tow mirrors for my 2019 Jeep Grand Cherokee but nothing would fit properly until I bought these. Love the ratchet style clamping system. Fit perfectly. Great product for my SUV.

After reading lots of reviews on several mirrors, I decided to buy the K-Source Universal Towing Mirrors. Oh how I wish my truck could use the ones that slip over the existing mirrors! I was prepared for a fight, based on reviews, and boy did I get one! I truly needed a third hand when figuring out how to attach these. I was bound and determined that I could do this on my own. No mirrors were going to defeat me! I did ask my husband to come look at them. He started to help but I shewed him away. After a lot of words that don’t normally come out of my mouth and a few tears, the first one was on! Then I had to go do it again in the other side! I’m pretty sure the neighbors heard me yelling. But I persisted! Lo and behold, this 67 year old Grammy did it! It was clear they would not stay on by themselves, so I grabbed a couple of bungee cords and wrapped them around the housing and they aren’t going anywhere. I have left them on my truck. No way I’m going thru that every time we return from camping. I will take them off at the end of camping season. Delivery was really fast. I was disappointed that one box was brand new and the other was smashed and taped, an obvious return. I would have been very unhappy if there was a piece missing or if something was wrong since this was my first purchase with etrailer. Overall, the mirrors work, they do not shake and I find I don’t use the truck mirrors now. Very happy with my purchase.

Fitted on 2024 Toyota Tundra SR5 CrewMax Cab w/ Stock Mirrors No vibration issues with either mirror. Turned left and right side clip on mirrors vertical so the did not overlap truck mirrors. Right side no problem with attachment and was able to adjust truck mirror. Could also see father back along right side of a 24’ travel trailer than just looking in truck mirror. Don’t expect to see behind on right side any vehicles tucked up close. Left side mirror attachment had to be modified so I could adjust truck mirror without interfering with clip on mirror lower L “hooks”. I put a rubber blocks under the lower L hooks so they were low enough to get under truck mirror glass yet still clamp to truck mirror housing. A picture tells the story. 7,000 km/4,200 miles later and neither mirror has loosened or moved. No vibration or distortion. Yes, I ran 2 zip ties as safety “chains” from the back straps to truck mirror arm just in case, they’re barely snug. I recommend these.

These mirrors helped tremendously when towing my Micro Minnie travel trailer versus stock mirrors on my GMC SIERRA 1500. The extended mirrors enabled to better determine when it was safe to move back into my lane after passing a vehicle and allowed me to see better the vehicles behind trailer. Although there was an occasional slight vibration in the passenger side mirror, it did not disrupt the usability of the mirrors. The towing mirrors took only a minute or two to install and fit perfectly on the stock mirrors. Adjusting them properly takes a little more time and is easier when a second person helps. I am extremely pleased with this purchase!

So far, so good. I received the CIPA mirrors today and immediately installed them. Installation instructions are straight forward. I took a test drive of about 15 miles; there was no noticeable shake or rattle and the mounts did not loosen. As with factory curbside mirrors, objects are closer than they appear with the CIPA mirrors, too. Our first trip towing is a couple weeks from now. I will update my review after the trip.

The view is excellent. The mirrors do not vibrate. In speeds over 50mph, the tube would turn inside the clamps and the mirrors would turn upward, making them useless. Solution: I cut off a finger from a nitrile rubber glove and pushed it over the tube. Now the mirrors stay put.

The top bolt holes do not match my 1997 F250. I will have to drill and tap a new hole for the too bracket to fit. Overall, very nice quality! Quick delivery as well

Quality item. works well after installation.

Love these mirrors. They were so easy to install and they look nice on my truck. Still need to see if they travel well pulling my RV, but they are pretty secure so don't think there will be a problem.

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.

Delivery was quick. The mirrors slipped on with ease and fit well over the existing mirrors and looked almost factory attached. Then came the task for securing the attachments to the vehicle. While the concept is easy someone forgot to check deminsions of the parts and were to short to work on my vehicle. I contacted etrailer by chat and asked if there were alternatives for securing the mirrors and unfortunately there weren't any. Then came my decision to use heavy duty electrical looped through the hole the sent hardware was to be inserted through. Unless you look closely they are not easily seen. When I want to remove the mirrors I simply snip the cable tie on each mirror and ues new ones the next time I need to use the mirrors. While my "fix" works they only 3 star because to the attachment hardware.

The extensions fit the mirror but the hardware to hold them on won’t work. I’ll have to make hardware for them to work properly.

Unable to tighten mirror clamps enough to eliminate mirror from shaking, preventing clear image while driving.

The mirrors were just what I needed and work well on my Toyota highlander.

The company was fast and gave lots of updates for shipping. Once i received product my concerns were met. The straps are BARELY long enough to connect around my mirror. Once it is straped properly the tension on straps pulls them right out of the retaining clip. I ordered these because i have a 11 silverado just like what was in the product pictures. Save your money and get something else because theres no way these will make it down the highway they will barely stay on just sitting here. Kinda disappointed because i bout these for our first camping trip this weekend but these will not work. Seems like a good company just crappy product.

Thank you for the easy shopping experience and delivery.
