Most Popular K Source for 2001 Chevrolet Avalanche

I wish I'd had these mirrors 15 years ago. I can finally see down the side of my two place sled trailer. That being said, man, these things are a pain to install. Probably didn't help that it was 6 degrees outside when I did it. I ended up removing 1 srip of tape from driver's side and 2 from passenger's side. Even then, it was a fight. They do bounce a little, but that will be corrected this Spring with a little Goop from Wal Mart. I plan to just keep them on year round. Great product. 4 stars for difficulty mounting and 2 stained elbows.??

As stated in other reviews, the mirror extensions can be difficult to out on. Finally had to remove all three pieces of the protective tape that is supposed to protect the finish on the factory installed mirror to get the extensions to fit. Mirrors to shake quite a bit when driving even after tightening them per manufacturer directions. Ok product for the price.

Sent me the wrong item. They sent the Longview tow mirrors instead of the item above. I just authorized a return on the wrong mirrors and will be doing business elsewhere. Sorely disappointed in etrailer.com. Instead of sending Item #KS80900, they sent me a Longview Product that does not fit my truck, which has a chrome cap on the towing mirror.

Very tight fit, afraid I might break them some day but have held up well to date. Minimal wind vibration, I love that my power mirrors still work with these in place. Looks like original equipment when the are installed. eTrailer provided speedy delivery and kept me well informed on the status of my order.

I am very happy with these extendable towing mirrors. They're high quality in looks and constuction. The mirrors are larger than the mirrors they replaced and give a much better view to the rear. The instalation took approximately 1.25 hrs. done at a local body shop. They will be a great help when towing our travel trailer.

I ordered there mirrors based on reviews. Fast delivery? I hit send on my order then the doorbell rang. They fit perfectly, the wiring harness snaps right in place with new hardware attached. The view they provide is a game-changer compared to stock. And they don't shake, which seems to be the problem with the others. Thanks for a quality product that works!

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

I'm very happy with these. The video made install a snap. I installed on a 2010 Silverado 1500. I did not have turn signals in the mirrors before, but I do now! These mirrors fit great, work exactly as advertised, and are worth the price.

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

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

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.

I already had mirror extensions because I pull a travel trailer, but one got broken off so I needed a replacement. I chose this different model and am happy I did because it gives me a clear view of what might be coming up on my left side. I can easily see if I am able to change lanes. I do still like the other model though, and it works perfectly for the right side because I have three different aspects to help me know when to pull back in after passing. I highly recommend both models. Shipping was fast.

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.

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.

I chose not to go with power mirrors. I'm glad I bought these, the fit is perfect, and the lower mirrors are fantastic to see cars in your blind spot even when not extended for towing. Very happy with my purchase. 2002 avalanche

Great quality. E trailer is the best company to deal with.

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

They will not stay on the mirrors for a 2023 Grand Cherokee. After very careful installation they fell off because the shape of the mirror is rounded and you cannot get a good grip to hold the mirror on

I was very disappointed these mirrors were shipped in a thin display box without a cardboard box to protect them. I have attached a photo of the box bottom. Mirrors appear to be ok but not sure I would chance ordering anything more from you.

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?

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

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.

These mirrors have helped me tremendously as alot of times I am by myself trying to back the trailer in and these help give me a better view of where I wouldn't otherwise be able to see with just the car mirrors.

Works well. I actually mounted mine to the outside edge of the mirror after reading the one review where he mentioned that if you put it where it is shown the mirror cannot fold in. It works great and they look decent. The blue color does kill the glare at night. For the price you can't go wrong.

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.

Very good quality construction. Very good fit for a non-custom mount. Thick rubber straps are stretched over the car’s side mirror and hold the mirror well. My car is a 2017 Ford Expedition EL. Note: when you fold in the car mirror the towing mirror partially blocks the progress so that mirror stops early. It is still folded but not as completely as without the tow mirror. And yes, they are two identical mirrors so on one side the straps go up, on the other side they go down.

BUYER BEWARE!!!!!! I had great hopes for these mirrors. They look great. They appear to be very adjustable right out package. They fit on my Tacoma securely. They don't interfere with the function of the stock mirrors. Everything was moving along "swimmingly". Then I sit inside my truck to do the final adjustment (moving the actual mirror to get the correct setting and lock it into the "sweet spot"). The new Mirror is very stiff...doesn't want to move. Well, its new...so....Okay, I don't want to ruin anything...so.... No worries, I go get a phillips screwdriver to loosen the back screw a smidge so the friction adjustment can work . Come back start to back the screw out just a smidge...nope...still can't adjust the...wait...unscrew some more....that's not an adjustment screw at all. That just screws directly into the back of the mirror to hold it solidly in place. Worse yet, There is no friction mechanism on the back of the mirror at all. It is one solid piece of plastic. The molded plastic replicates the look as if it has the ability to move, but in reality....There is no way to do small mirror corrections once you have this thing installed. What the Actual people?????!!!!!!???? If you can't do minor adjustments to the mirror while you are in the vehicle, then the mirror is completely useless. I wouldn't recommend this product to my worst enemy. It's a piece of crap. DO NOT BUY!!!! A complete waste of time, money, and shipping costs. Now, I have to incur more shipping costs to send this POS back to etrailer. Hey, etrailer....Do Better next time!!!!

The people were very helpful. The mirrors went in perfectly. Use them extended when pulling trailer. Thanks

Love the new mirror, looks just like the factory one

They were easy to install (once you figure out where the strap release button is located) and worked like a charm! I drive a 2017 Suburban and towed a Keystone Bullet (about 8 1/2’ wide and 30’ long) 160 miles today without any issues. The mirrors are not what I’d call pleasing to the eye, but they certainly provided an additional 18” of span, enabling me to look down the sides of the trailer and see cars behind me.

These are working out great! I'm now a wiz at putting them on too. They're great quality, sturdy and snug fitting. Very happy.
