They fit great and work even better

The mirrors attached easily over the existing ones on the truck. They do not look like a cheesy add on. They actual look like they are part of the mirrors and not just a quick attachment for towing a trailer.

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.

Mirrors work good. Very happy with them, online videos on installation helps especially with removing door trim pieces which for me was the majority of the time and difficulty. It plugged into existing wire harness and everything works like it did with OEM mirrors (able to control tilt using door buttons, etc.) I just wished they would have sent the nuts with washers like OEM. I used on the OEM original nuts since it had washer base on the 3 but had to go buy a washer for the 4th nut since the 3/8 hole almost allows nut to go through the hole.

Changed out my stock mirrors for these since I have a camper to pull. The installation was medium difficulty because working around the trim was a little difficult. I did everything the video installation showed, it was just a kind of a pain to work around. Other than that, pretty straight forward, took me a couple hours and I was all done. The quality is great and works as advertised. I’m extremely satisfied with this purchase.

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.)

Arrived in good condition

THese mirrors came in timely manner. They appear high quality. I have not used them yet but they appear as if they will work great. Have not had any issues with any etrailer products yet. Thank You!!!

I paid for 2 day shipping and it took 4 days to receive my order. I have not heard back from anyone to correct my billing

Perfect fit and way better than the clip on mirrors we had previously. They look like they belong on the truck all the time.

I was impressed on how well they fit the factory mirror. Will be pulling the camper in a week or two. Thanks

So far happy with fit, install and initial quality. Product install video was helpful. Looking forward to towing travel trailer with these as the weather improves into spring.

I bought tow mirrors a year ago from etrailer.com and I couldn't ask for more they have held up very well and am pleased to recommend them.

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.

Fit really well and look great

Thanks for fast shipment. Great getting what I ordered so quickly. That has not happened in 2 years.

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.

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

Used mirror in great shape delivered quickly! Great service!

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.

Great people Fast Shipping

Flange on bottom prevents you from mounting mirrors in center. The mirror hangs below the bottom of the factory mirror assembly making it look very odd and out of place.

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.

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.

Finally an add on mirror that works great strap on ones from (another site) suction cups from (another site) useless I am very satisfied with my purchase of these.I can change lanes and back up with confidence now and didn't have to spend dealer price for extension mirrors money well spent !!!

I’m couldn’t be more pleased! Easy to install and very stable they don’t interfere with the working of the factory mirrors and even allow the turn signal functions, highly recommended

This is a reorder of this product. These are great, low cost, attractive looking extension mirrors. Very little vibration while driving which adds to good rear visibility. I've tried other extension mirrors that had a lot of vibration, which made it hard to see well. However, when installing and removing these, you have to push the outside edge of the mirror all the way in, so that it doesn't make contact with the body of the truck mirror. If you don't do this, these mirrors can crack when installing, which is why I'm ordering this second pair.

These fit well and look good. Looks like a factory add-on. Prior mirror extensions I had were kind of cheap looking and more difficult to put on. Haven't tried them on the road yet to see if there is any vibration in the mirror, but so far I like them!

Fit my 2019 Chevy Suburban perfect. Easy to snap on/off without any tools or adjustments. I have a 7.5' wide enclosed trailer that I pull some dirtbikes in. It works perfect. Gives me just enough to see further behind me. Not sure how helpful they would be for an 8' wide box. Works for me though. I definitely recommend them. Blend right in and look clean too.

I purchased this because there wasn't an alternative side mirror extension that form fitted my Yukon Denali side mirrors. All of the other units I tried looked like UHaul add ons. They vibrated while driving and just looked tacky. These fit nicely. Are a little difficult to snap on but not prohibitively. I do remove these when I'm not towing my camper so ease of removal and installation are important to me.
