Most Popular Electric for 2010 GMC Sierra

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.

Installed on 2008 Gmc Sierra Sle. OEM mirrors were power adjust with defrost function. New mirror allowed me to add the turn signal function, however I did check the wiring harness to ensure it was compatible to take this function before the purchase. New mirrors were good quality just as good as OEM if not better. Installed they definately enhance the trucks overall appearance. I will be using these to tow a 30’ travel trailer so the larger mirror surface will help with visibility of the trailer. The only con is the main mirror in the housing does slightly vibrate when hitting bumps in the road, its very minor though and otherwise is stable on smooth surfaces.

work great

Evwerthing worked well and the delivery was prompt.

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.

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

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

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.

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.

Look great fit well and should work well for towing blind spot sensor works well maybe too well

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?
