Most Popular K Source for 2003 Ford Excursion

Very easy install, perfect fit. Looks like it came from the factory. The electric controllers work perfectly. Truly it was "plug n play".

The mirrors fit perfic and had no issues installing them in my truck. I like the product and it's almost the same as the original one. When I had the old ones, they made a lot of noise when I was adjusting the mirrors. And this ones theirs no noise . Just silence when adjusting the mirrors.

I wish I put them on years ago great vision around my side tool boxes no more blind spots

K source extendable towing mirrors were of quality equal to oem and installation was very simple.

Great customer service and outstanding product! Both exceeded our expectations!

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.

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.

These mirrors are good, but not great. I bought these because nothing else fits my 2004 Ford Expedition. They allow me to see around my trailer much better than the factory mirrors, but the have a slight vibration driving down the road. They also make a very noticeable noise from the wind going between the factory mirror and this product. Finally, one of the straps came off when I tightened it a bit too much, but didn't break. The picture below was done in humor (I took my trailer through a drive through, thought it was really funny, and had to take a picture. The picture is a good shot of the mirrors.)

The KS81600 (pair) snap-on mirrors mounted quickly and fit snug and beautifully to my 1999 Ford Expedition Eddie Bauer Series with contoured mirrors, and did not impede the existing Ford mirrors whatsoever. However, I have a problem with the focal distance of the passenger side KS81600 mirror that I received. See photos. It's magnification is quite different from the truck mirror, and shows only a small, magnified area of the distant background. In contrast, the KS81600 driver side mirror has a similar focal distance as the Ford driver side mirror, offering more of a long and broader view. I could live with the driver side view, but not the passenger side. I'm unsure if this difference is intentional or a product error/mis-match. I've contacted the eTrailer experts on the matter. Alternately, I also ordered a pair of the KS3891 "clip-on" mirrors, with the ratchet system. While I think this product offers a much broader view on both sides of the vehicle, they are not near as easy to put on as the KS81600, never quite go on in exactly the same position, and are not a perfect fit to my contoured Ford mirrors on the passenger side. In addition, the thicker clamps of the KS3891 make contact with the Ford mirror glass and impede my ability to fully adjust them. I will post a separate review of them. The KS81600 is a much cleaner, easier product to install and secure. Unfortunately, the focal distance issue is a deal killer for me, and I'll probably keep the KS3891 which provide a broader view on both sides of my rig.

I have a 2002 f150 Lariat supercrew with the turn signals on the mirrors and these fit perfectly over them with plenty of room to still adjust the mirror. I tow a 19ft travel trailer and can now see the traffic behind me, no more hoping there is no one coming up on me as I change lanes, and the mirrors barely vibrate so you can see very clearly in them. They fit nice and snug on the truck mirror so there is no worry about them moving around or falling off. The only negative for me is the bottom clip scrapes up the truck mirror a bit every time I take them on or off, so be carefull. Overall very happy with them.

The black paint could have been polished out more, had some scratches on it and wish the paint was “darker” it’s kinda light looks a little blue
