Most Popular Full Replacement Mirror for GMC Sierra

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.

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

Great mirrors, very pleased with them!

I love my mirrors thanks etrailer they was simple to put in no hassle at all

These mirrors are great quality very close to OEM . The installation went very well. I did take the door panel off to make it easier to get to the two lower fasteners, just to make sure I didn't loose the nuts inside door. There was very little vibration in the mirrors, I was a little worried about that by reading previous reviews. The mirrors held their positions, folded nicely when parked in tight spots. Everything said this is a great quality product

Great customer service! Free and fast shipping. The glass on the mirrors shake when your on the highway. I don't know of it's all towing mirrors or just these. Easy to install an fit perfect. Overall I'm happy with the product. Thanks e trailer for the great customer service.

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.!!!

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

Won’t stay locked in stoned position

Love these mirrors! Have had them on the truck now for a year and they work perfect and give you a lot more visibility than the standard short factory mirrors. No need for aftermarket extensions with these. Plus they slide out if you need even more visibility but we never had to use that alternative yet cause they work great just the way they are. We tow a tandem axel 7x14 cargo trailer and have plenty of visibility to see backing up and nicely down each side while driving. Much safer in heavy traffic. Installation was very simple and the mirrors bolted right on with exacting fit. I would totally recommend these if your needing better visibility over the small OEM mirrors for towing or just daily driving.

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.

Towing Extendable after market Mirror fit perfectly and looks good now. Time will tell more. Easy mounting and good instructions. Only concern was slow shipping with UPS transfer to USPS.

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..

Works great

Just what we wanted! They arrived in great condition and they are installed!

Looks just like the broken one so very pleased.

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?
