Most Popular K Source for 2016 GMC Sierra 3500

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.

great mirrors

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!

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 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.)

I have a 2016 Silverado 2500 HD LTZ with factory mirrors including heat, turn signal and electric adjustments. Have been towing a 24 foot Travel trailer and the factory mirrors are adequate. Am used to swerving a little to see behind the trailer before changing lanes. Am now going to tow a thirty foot trailer and decided the mirrors would not do. Looked for an oem towing mirror but was shocked by the price. $[XX] plus for one that has all the functions of the LTZ mirror. Looked around, watched videos, read reviews and decided to puchase these mirrors. Got them today and they installed in a snap. Have yet to use them but will be shortly. Initial impression is that they will provide the extra vision needed to pull this trailer. Only complaint was the condition of the package received by USPS. The product was shipped in the manufacturer packaging which was probably not a good choice. Fortunately the mirrors were undamaged as can be seen in the photos. In any case, the mirrors fit and seem to be well constructed. Hence the five stars. Time will tell if I made a good choice.

These could be the best mirror extensions I’ve ever owned. They are totally worth the cost. Scratching of the factory is an issue during installation and dismount. I used helicopter tape to minimize the problem spots.

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.

THE PRODUCT IS GOOD BUT NOT GREAT. THE ENTIRE ORDERING PROCESS AND QUICK DELIVERY WAS EXCELLENT.

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.

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.

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.

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 love it,

Fit perfect !!!!!! Excellent quality.

I had ordered a set of strap on tow mirrors and was dissatisfied with the fit. They were easily returned and I decided I wanted this pair for complete change out. These mirrors are beautiful and large. They extend approximately 23" from the attachment point to the vehicle. It fits in the same vehicle footprint. They look really good and the lower mirror is a wide angle for added view.

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.

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.

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

Fast shipping and the instructions on the website were fantastic. it worked just like the video said. Thank You it is a great product
