Thank you for reaching out and seeing if I was satisfied with your products. The bolt pattern looks good and the mirrors are what I expected in quality. Today's the first day I have had to disassemble the door on the truck to install my new mirrors. Part #6207576G is the # on the box I Receved. Unfortunately the electrical harnesses do not match up to my vehicle. The truck is a 2005 GMC Sierra 2500HD Turbo diesel w/ 6.6 bed. I confirmed on your website that I had selected to correct mirror and it appears to be in the correct year range. Can you help me to resolve this problem. Best Regards

Our main concern on aftermarket mirrors is the "shaking" due to poor design. We were delighted to find that these mirrors do not shake at all. We tow a large 5th wheel so seeing in the mirrors is huge for us. Installation was relatively easy plug/play and did have to remove the door panels. We are very happy with our purchase and would recommend these mirrors to others.

work great

great item plug and play looks factory. a little vibration while driving

Mirrors arrived on time and in good condition. Installation was easy. Should help when towing our travel trailer. Viewing area is larger than with stock mirrors which will be an asset when backing.

The mirrors I purchased were delivered very quickly. They were in great shape. I like very much the look they gave my truck. The only thing I find wrong is my fault, I would order the auto adjust . NO FAULT of the company my fault in ordering. Will order again from them.

Perfect

The delivery was fast, the quality of these mirrors are great, and the installation was easy. Visibility is MUCH better when using our camper! This product is a no-brainer.

Evwerthing worked well and the delivery was prompt.

Mirrors are perfect!! Great extension capabilities and they hold in place when adjusted. Very satisfied with the product and company

The replacement mirror I purchased is a great product. Although it’s not 100% exactly identical to the factory mirror it’s not noticeable to a average person because the mirror glass is all that’s slightly different, very slightly! The slightly difference in comparison outweighs the cost of a factory replacement by far.

Identical OEM Mirror. Not one thing was different. Perfect fit. Will use you again if I need a vehicle part. What sold me on the K-Source mirror was the many different views and measurements you provided and the technical info you gave on this product. I could have gotten one a little cheaper, but I feel that's just what I would of got. Thanks

Bought these mirrors for my Honda Pilot and they worked great for towing my trailer. Ended up buying a bigger truck (GMC Sierra), and the mirrors fit that one as well, so I didn't need to buy another set. Fit is easy and adjustable - just need a small gap between the mirror and casing.

Just got back from a trip. Mirrors attached with a little bit of effort on my part. No vibration and gave me the field of view I wanted. Shipped fast and order was right. I liked that I could confirm the fit on the order page. I would recommend these mirrors to anyone who needs just a little more rear vision and etrailer for a very good transaction.

Very easy to use (2013 Sierra) and definitely helps with the blind spots. The road vibrations cause the smaller portion of the mirror to slightly shake but to be expected with the crappy California roads.

Great product, fits perfect on my oem mirrors, Great price n I’ve seen some mirrors same type for twice the cost of these. I recommend Etrailer to all my family and friends. Forgot one thing very quick shipping. Thanks Etrailer....

Love the new mirrors they are just what I needed. I previously purchased mirrors that would install over the existing mirrors when towing large and/or long loads. However, these new are much better and always available - just pull out for large and/or long loads. Also, the new mirrors were very easy to install; and, again I cannot says to often that the fit certification and installation instructions from Etrailer are right on always. Finally, if you have anyone who would like to have my previous mirrors that were purchased from Etrailer let me know.

Identical to original GM part. Good quality and workmanship.

Work GREAT!!

Seems ok However I have not installed it yet so I do not know if it works yet

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

The mirror was easy to install and the mirror does not vibrate when driving, so vision is clear and stable.

Working great wished i would have gotten them a long time ago

Exact fit

Work very well after being installed for a year. As other reviews mention they don’t sit level with out some washer shims on my 2006 GMC 2500HD. My wife likes the a bit higher and it doesn’t bother her that they are not level. Only reason not 5 stars is they require a fair bit of force to extend and retract would be nice if it had a smother sliding mechanism.

I purchased a set of these mirrors in September, 2013 for my 2003 Silverado 2500 HD crew cab. I use the truck for pulling trailers to different events during the warm months. I installed them without a problem (even though they came with no instructions). While testing out my new mirrors, I immediately noticed that the upper part of the passenger mirror (the part that is powered by the electric motor) had a significant element of vibration at highway speeds. I contacted eTrailer, who arranged to have a replacement mirror sent to me. Since it was a single mirror, and not part of a set, it took K-Source a couple of weeks to get the replacement mirror to me. I installed the new mirror, but my towing season was over and I never tested it on the highway. This April, I start towing again. The mirror vibrates as bad as the one that was replaced! eTrailer put me in touch with K-Source. Their response was "Sorry, the mirror has a 90-day warranty. You are outside the warranty period". REALLY! After multiple e-mails and phone calls to K-Source, they agreed to "assess" the mirror if I paid to have it shipped to them. They shipped it back to me and said that there was nothing wrong with the mirror, that I must have installed it incorrectly. REALLY! Only the upper pane vibrates, not the body of the mirror or the lower wide-angle mirror. They would not replace it. If you are in the market for this type of mirror, I would suggest you look elsewhere.

No comment needed

These towing mirrors were exactly what I wanted. They fit my 2001 GMC Yukon XL perfectly, utilizing the existing hardware for adjustments and defrost. They extend easily (manually) when towing our pontoon boat, and collapse (manually) against the vehicle when going through a car wash. I should have purchased these years ago, instead of waiting until one of the original ones broke!

Love the mirrors, exactly what I needed. ETrailer would get 5 stars if not for a bit of a fit problem. Both sides fail to make contact with the window molding at the top of the triangle (pics). A separation angle begins just above the main body and pulls further away from the window molding to the tip of the triangle. The passenger side is gapped worse 1/4" than the driver side but both will undoubtedly allow water seepage into the door frame. Would hate to have to caulk these things but tightening and shimming with washers has not worked to change angles at top.Thinking over solutions to save this install.

I ordered K-Source towing mirrors.. back ordered but eTrailer worked magic.. I did read one line in the instructions, (DON"T DROP A BOLT INSIDE THE DOOR PANEL) Installation was 20 minutes start to finish with a 10mm deep socket/ratchet and screwdriver. I did NOT remove door panels, you can bend them back far enough to reach all three bolts. Remove the triangle plug on top of the door that's behind the mounting bolts for the mirrors. Remove three 10mm nuts and swapped mirrors. It could go faster with another set of hands to hold the mirror as you install the bolts. Note1. Be sure to use the foam piece that comes with the new mirrors, it's a gasket to help make the whole thing fit. I think that's photo number three. End result, these mirrors do yield to pressure to make them swing back if you're in a tight spot. Road trip is next to see how much they may move. I'm very impressed with the quality construction, they feel/look top notch. These are OEM factory quality indeed. Thanks again Samantha G..
