Most Popular K Source for 2020 GMC Terrain

Easy to install and adjust. Suitable for cars and SUV's where the trailer is wider than your Tow Vehicles mirrors allow for safe travel. Clamps to a wide variety of existing mirrors. Just make sure that they are strapped down firmly. Frank M

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.

After reading lots of reviews on several mirrors, I decided to buy the K-Source Universal Towing Mirrors. Oh how I wish my truck could use the ones that slip over the existing mirrors! I was prepared for a fight, based on reviews, and boy did I get one! I truly needed a third hand when figuring out how to attach these. I was bound and determined that I could do this on my own. No mirrors were going to defeat me! I did ask my husband to come look at them. He started to help but I shewed him away. After a lot of words that don’t normally come out of my mouth and a few tears, the first one was on! Then I had to go do it again in the other side! I’m pretty sure the neighbors heard me yelling. But I persisted! Lo and behold, this 67 year old Grammy did it! It was clear they would not stay on by themselves, so I grabbed a couple of bungee cords and wrapped them around the housing and they aren’t going anywhere. I have left them on my truck. No way I’m going thru that every time we return from camping. I will take them off at the end of camping season. Delivery was really fast. I was disappointed that one box was brand new and the other was smashed and taped, an obvious return. I would have been very unhappy if there was a piece missing or if something was wrong since this was my first purchase with etrailer. Overall, the mirrors work, they do not shake and I find I don’t use the truck mirrors now. Very happy with my purchase.

Fitted on 2024 Toyota Tundra SR5 CrewMax Cab w/ Stock Mirrors No vibration issues with either mirror. Turned left and right side clip on mirrors vertical so the did not overlap truck mirrors. Right side no problem with attachment and was able to adjust truck mirror. Could also see father back along right side of a 24’ travel trailer than just looking in truck mirror. Don’t expect to see behind on right side any vehicles tucked up close. Left side mirror attachment had to be modified so I could adjust truck mirror without interfering with clip on mirror lower L “hooks”. I put a rubber blocks under the lower L hooks so they were low enough to get under truck mirror glass yet still clamp to truck mirror housing. A picture tells the story. 7,000 km/4,200 miles later and neither mirror has loosened or moved. No vibration or distortion. Yes, I ran 2 zip ties as safety “chains” from the back straps to truck mirror arm just in case, they’re barely snug. I recommend these.

My order arrived. I was disappointed it did not come in a unidentifiable box as it was a Christmas gift for my husband and he got the mail.

These worked great on my wife's Yukon. Installation instructions were clear and direct. They held up very well traveling 75 mph down the interstate; No jostling around or coming loose. I loved the additional two mirrors. Having the three total different angles while pulling a trailer was extremely helpful. Would highly recommend this setup.

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.

I went right away to try them on my truck. I have a 24 Denali ultimate 1500 Denali and I have a couple of cameras on my side mirrors. The straps are easy to maneuver around the cameras to avoid issues there. Good snug fit I have not taken it out yet to test these in real road conditions but so far so good.

Worked well and as expected. Still can't see as far behind the camper as I would like on the passenger side. Strap them on tight. They shook very litte but some, not enough to be bothersome. Later,I did find them less expensive elsewhere, oh well. Straping them on is tricky to not cover the cameras underneath the truck mirrors. Truthfully I use the camera on the back of the camper along with these mirrors and get additional views from the Chevy cameras as well. I'm not a truck driver and only pull the camper on occasion so I need all the "eyes" I can get especially driving through Nashville and Atlanta.
