Most Popular K Source for 2021 Chevrolet Silverado 1500

Quality product with little vibration. Mirrors are kind of small but get the job done. Came with padded tape inside unlike my last set for my old truck. Thanks etrailer.com! Free shipping was real nice.

Everything went smooth came in quick thank you

Excellent fit! They look factory. Install is straightforward and didn't take 45 minutes to install both sides. Watch the install video for a quick reference. These were on back order at the time I placed my order. etrailer staff kept me informed and updated as status changed all the way to delivery. Excellent customer service once again. This is my 4th purchase from etrailer and I'll use them again!

Decided I was done with clip on tow mirrors and purchased a set of these for my 2017 Silverado. Install was less than 45 minutes, fits great. I will make a suggestion, I put magnets under the area where you have to drill the extra hole to catch all the metal shavings.

Fit, finish, looks, and function are great. Installed both in under an hour, including drilling additional mounting hole. Vendor should include the extra nut and washer needed for mounting. Great value also- GM dealer wanted $1200 for the same thing!

Plug and play after drilling a hole for the 4th stud.

Fit nice and went on easy

Packaging was great. Fit and function of mirrors are as advertised.

For plastic, they seem pretty heavy. We'll see how they do after towing at highway speeds. The driverside restricted the stock mirror so I had to lower my seat and hopefully it will be ok. Instructions are weak.

I ordered these clip-on mirrors as a gift. So the only comment I can make at the time is that the ordering and delivery process was great! E-trailer was easy to use. I enjoy getting the periodic emails. Click on the ones that might have an interest...pass on the ones that don't.

The extended mirrors were easy to install and adjust, no vibration or rattle will driving. Installed and used them for a 1500 mile trip, towing a 22 ft Travel Trailer. They were very useful in making a safe journey. There is no adjustment for their extension which would have help greatly in seeing more of the back of travel trailer, they would work extremely well with flat bed or boat trailer.

I had previously purchased the CIPA Universal Fit Towing Mirror - Clamp On - Adjustable Length - Steel tow mirrors thinking the clamps that held the tow mirrors onto the vehicle mirrors were made of metal but they are made out of plastic and one broke during the first installation. Since you have to tighten the screws on the clamps everything you install them I returned them. I previously had a cheaper pair of tow mirror secured by a strap so I thought I would give these a try. In addition I prefer this type of mirror verses the tow mirrors that slide over the vehicle mirrors given these have a larger mirror surface and allow you to see a larger area. Installing these mirrors the first time takes a little bite of extra time for the initial set up. The ratchet system works great and secures the tow mirrors firmly to your vehicle mirrors. There is little to no mirror vibration and I am able to have a good view of my trailer and the cars behind the trailer. I have used these mirrors on two different trips totally approximately 700 miles. There has been no problems with the mirrors and I would highly recommend them.

I would rate this product as only satisfactory. I always had trouble with the straps when attaching them to my existing mirrors. On one of my last times using these mirrors one of the straps actually blew off as I was going down the road. When I purchased a new vehicle I was able to find mirror extensions that slip over my existing mirrors, and perform much better.

Easy install. Quick Delivery. Easy web site. We'll see next year when I use them how they work.

Love them, I have ordered many of items form online service but I must say that E Trailer is the best. What they described was excellent for tow mirrors. Fit like a glove, easy to install and did not come off at 70 mph.

Good product. Looks better than other add-on tow mirrors. Easy install and good fitment.

Received the mirrors in good shape...frankly, chose to have them professionally installed via body shop to make sure all went well...and it went very well...great product and appreciated the help getting them selected for the right vehicle...would recommend these mirrors and this company to anyone...

OEM Quality! They look like they could have come on the truck. Installation was a snap. The fit and finish are above standard. I only wish they offered the marker lights and turn signals on the front sides of them.

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 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.

They fit perfect on our 2010 GMC 1500 SLT 4x4. They're exactly what we needed to pull our camper with. Thanks for an excellent product!

Simply installed and removed, these mirrors make all the difference when towing our 33’ trailer. They easily adjust to allow the best views of both the trailer and surrounding traffic. I highly recommend this product.

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

Used mirror in great shape delivered quickly! Great service!

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.

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.

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

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.

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.

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.

Good blind spot coverage. Fadt shipping.

I absolutely love these mirrors! Very easy to install, about 15 minutes per door. Adjustable from inside and no shake. Can't wait to pull the RV with these mirrors instead of the clamp-ons.

I installed these ksource mirrors on my 2006 Chevy Silverado and as advertised the installation was an exact fit. It took approximately 30 minutes per side to install. The mirrors were an exact fit and the wiring was an exact match. I recommend these mirrors for anyone pulling any type RV needing full side views and beyond on either side of the towing unit. Thanks etrailer once again.!!!
