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.

After years of replacing mirrors from other sources I purchased a pair of these. There fantastic, plenty of adjustments. Got covid on vacation, really sick and did not properly install mirror. Not broken but scratched badly from asphalt at 55 mph. Purchased a replacement, scratched one is my spare.

These mirrors are good, but not great. I bought these because nothing else fits my 2004 Ford Expedition. They allow me to see around my trailer much better than the factory mirrors, but the have a slight vibration driving down the road. They also make a very noticeable noise from the wind going between the factory mirror and this product. Finally, one of the straps came off when I tightened it a bit too much, but didn't break. The picture below was done in humor (I took my trailer through a drive through, thought it was really funny, and had to take a picture. The picture is a good shot of the mirrors.)

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.

Since this is the second one in 4 years-1 star…. Because I had to replace the passenger side a couple months ago- thought it was a fluke- now the driver side failed…. On a garaged truck- used primarily for towing and adult owned. Should’ve bought OEM for the same price at this point

Purchased about a year ago. Installed with no issues. No issues since install. Can't tell difference between new mirror and OEM.

Perfect fit. George was very professional and helped me pick the right mirrors for my Chevrolet Silverado. I tow a fifth wheel and no vibration like the clip on mirrors. very satisfied with your outstanding service. Will continue to do buisness with etrailer. Next purchase will be airbag system.

I installed them on my 2018 Silverado. The fit is good and they look like they came with the truck. Not extended the outside edges of the mirrors are 8'-2" and extended they're 8'-10". They enable me to see around and past my enclosed 8'-4" wide trailer. If you've never been inside a door panel before I'd suggest watching a couple of videos prior to starting. I had to drill one hole in the door (original had 3 bolts this has a fourth stud). I'd have given them a 5 star except the glass shakes slightly when they're fully extended and I hope that doesn't get worse.

I originally ordered these mirrors in 2019 for my truck….4 years later I am having to replace now both of them. I replaced the passenger side in august, thought that it was just a bad mirror….The drivers side is now failing as well. For the price I expected them to last longer than 4 years on a truck that is garaged nightly and really only used for towing. The truck does not go off-road, so there is no abuse or reason both mirrors should have failed. Had I known I was going to have to replace both…I would’ve gone with a different product.

These are great mirrors when I'm towing the trailer. Wish they would slide in and out a little easier but I can deal with it.

Parts came in one day early. Prefect match for my 2015 3500 HD Chevy.. I called my order in and the lady that placed my order was outstanding.. She was very customer friendly. Thanks and I will be using etrailer again.

I went right away to try them on my truck. I have a 24 Denali ultimate 1500 Denali and I have a couple of cameras on my side mirrors. The straps are easy to maneuver around the cameras to avoid issues there. Good snug fit I have not taken it out yet to test these in real road conditions but so far so good.

Worked well and as expected. Still can't see as far behind the camper as I would like on the passenger side. Strap them on tight. They shook very litte but some, not enough to be bothersome. Later,I did find them less expensive elsewhere, oh well. Straping them on is tricky to not cover the cameras underneath the truck mirrors. Truthfully I use the camera on the back of the camper along with these mirrors and get additional views from the Chevy cameras as well. I'm not a truck driver and only pull the camper on occasion so I need all the "eyes" I can get especially driving through Nashville and Atlanta.

great addition to the factory mirrors for towing. Simple to install and remove with absolutely no damage to the factory mirrors. The adjustable mirrors stay in place well. I now leave these towing mirrors on the truck , my wife likes the extra view even without the camper hooked up. The mirrors allow all factory lights and sensors to function properly.

Snap on Snap off Hold perfectly, come with storage bag for when not using. This is a great product Have used all summer and fall. put in bag for winter and using again I would defiantly recommend this

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.

The service from etrailer was great like always. These mirrors are for our 03 Yukon for towing a travel trailer.They are condsiderably larger than the OEM mirrors in the collapsed position, the once extended they are almost twice as long. The only problem I had is the directions are a bit generic and tell you to pry the power window switch panel from the door panel to access the wiring. The picture supplied shows the lock panel being pried off which is correct but the power window is screwed in from the backside so the door panel needs to be removed and then reach behind it to remove the wiring.

Fit just like the factory mirror with a lot cheaper price.

Used mirror in great shape delivered quickly! Great service!

Easy to install and greatly increase my rear view. I can now see past our 21ft camper. The led turn signals are also a nice option. Very happy with purchase.

Great company. I received exactly what I ordered. It fit nicely
