Best 2023 GMC Terrain Towing Mirrors

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.

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.

I do not normally do reviews. I am extremely happy with these mirrors. Easy to install and adjust. Very secure. Large mirror can be vertical or horizontal. Best part is they are stable at highway speeds, unlike other universal fit mirrors I have returned. Vehicle is 2018 Ford Transit van. Telescoping mirrors are not available. This is the best option I have found to safely tow a trailer. Great price and fast shipping from etrailer. Highly recommended.

This was a well made product and I really liked how adjustable it was. However, be certain to tighten the mounting screws securely. I thought mine were tight enough, but when an on-coming semi passed us the mirror blew off. Fortunately no damage to the truck or camper, but the mirror was toast.

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.

The view is excellent. The mirrors do not vibrate. In speeds over 50mph, the tube would turn inside the clamps and the mirrors would turn upward, making them useless. Solution: I cut off a finger from a nitrile rubber glove and pushed it over the tube. Now the mirrors stay put.

This mirror was the only one I could find that would work on my 2021 Chevy Colorado pickup. I have been very pleased with the mirrors. I have learned to check the tightness of the screw on clamps, each time I stop. I have lost two of these from road vibration. I now have 3 of them, so I have a spare if another one gets lost or broken.

As mentioned in previous reviews, the mirror does shake while traveling but not nearly as bad as I thought it would. It's perfect for guiding yourself when backing up into a spot. Just make sure you have it secured on the top AND the bottom of your side mirror or it will eventually fall off. (Luckily, we were in the campgrounds when ours fell off--no damage)

Pros: Very easy to install. Will fit on almost anything. Cons: Bit of a challenge to adjust the in/out tilt on fixed mirror housings. Would like a little more height, but it's OK. This is a good solution for the casual user like me. Installation is painless. If you need more control over height or tilt, this is not for you.

Purchased a pair for our 2017 Jeep Grand Cherokee towing a nuCamp 400 from FL to AK and back. Three months and around 16k miles. Pros - other than an adjustment the second day, I never had to adjust the tension straps again. They were easy to mount and did not interfere with our mirrors folding inward. They weathered three months on the road without issue though I was beginning to worry about the straps becoming brittle. I noticed this once I removed them. Had I kept them, I would have used some silicon to rejuvenate the rubber. Cons - the only con is they shake. They shake to the point that sometimes I couldn't distinguish what exactly was behind me. I knew there was a vehicle, but the distortion from the vibration prohibited me from getting a clear view of exactly what was behind us. Impressions - they worked for our trip but I knew I would want something else for our next long trip, so we invested in a Furrion Reviewing Camera.

Great fit for my jeep gladiator! And great price. We tow a travel trailer camper and these work great for the price.

Fit mostly well on vehicle. Have not used on road yet. Time will tell

Not a good mirror. Second time using it fell off my car and smashed in road. Thank goodness it did not hit another car. The foam pads slid off and you can not get a good grip. I returned and they are sending me same one, because it was after 30 days.

Product delivered quick to my house neatly boxed and instruction enclosed fits perfectly exactly what I needed thanks etrailer

I bought both sides for my 2011 silverado and they look really good they look like they are factory mirrors install very quickly about 1 minute a side and they still allow the mirror to fold in if need be and they don't hit the side of the truck when folded in they fit my needs just fine the only complaint I have is the mirror itself could be bigger its about 1/3 the size of my factory mirror you have a decent blind spot when using them you just have to check yourself and its not a problem other than that they fit my needs well and come on and off quickly so they work really well if you don't tow 247 but it you tow very often like for a living I would recommend the full replacement ones cause they have less blindspot but if you tow every now and then they will suit your needs just fine I would recommend this product it you tow every now and then

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.

They are ok for what they are. Easy to install and remove. They do not show as much as I thought but enough since I dont have factory tow mirrors.

Fit is great no issues

Works as expected once it has been adjusted for your mirrors. I leave them set and marked for right & left side mounting but don't leave them in place except as needed. Make sure you really tighten the strapping or slipping will occur. I only need them mounted when backing a small utility trailer that is hard to see with the truck mirrors.

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.

The mirrors were just what I needed and work well on my Toyota highlander.

Bought these for a 2016 Nissan Pathfinder. It made towing more comfortable for a a 16 foot aluminum boat that we take with us about 8 hour trip one way. It was easier to monitor blind spots when changing lanes. Adjusting can be a little bit of pain. But overall would recommend if you want mirrors to give a little bit more awareness of where your trailer is.

The company was fast and gave lots of updates for shipping. Once i received product my concerns were met. The straps are BARELY long enough to connect around my mirror. Once it is straped properly the tension on straps pulls them right out of the retaining clip. I ordered these because i have a 11 silverado just like what was in the product pictures. Save your money and get something else because theres no way these will make it down the highway they will barely stay on just sitting here. Kinda disappointed because i bout these for our first camping trip this weekend but these will not work. Seems like a good company just crappy product.

Used these mirrors on a few lengthy trips now and they have been steady and secure, I added bungees first time out in case they came loose, but no longer necessary. They do keep the adjustable mirrors on my 2015 Tacoma from moving, but I expected that.

Excellent Product…Easy to Install and the instructions were very easy to understand… These Mirrors fit perfectly on my 2016 Ram 2500 SuperCrew 4x4 Truck

Surprise ! Work so well I'm amazed. Took a while to get them adjusted just right but ever since haven't had to touch them. "Have used them while pulling 30' TT, my 21' boat, and my 20' enclosed utility trailer. They give a perfect sight line for all of them without readjusting. Just slip them on and off whenever I want them and away I go !

Perfect fit. I had purchased Longview towing mirrors for my 2015 Silverado that I just sold. Had great success with those mirrors (7 years). Bought these because of the longevity and ease of use with the prior purchase. I expect the same from these.

These Longview mirrors are very east to install on my 2020 Silverado. Driving down the highway, there is very little vibration. My extended view is great and will aid me when pulling my camper trailer. My only concern is the nylon(?) hook and knob that secures the mirror in place. This seems to be the weakest link. I would have preferred it be vinyl coated metal to make it less likely to break. This is the reason for the 4 stars.

The mirrors help me tow our Lance trailer safely. The adjustable mirrors benefited with a touch of dry lubricant on the joint inside the housing. Emily at etrailer was very helpful!

First set had a factory defect. The hole for the tension knob was not threaded. Replacement sent was also a defect, the mirror panel swivel was un-adjustable. Spend the extra money and get the correct OEM ones for your vehicle.

These trailering mirror extensions were purchased as a gift, however they fit perfectly on my dad's Ford F-350. Much cheaper than factory mirror extensions and perfect for his application.

This product came very quick. I like the way it slips on and locks in so easily. I will be towing a camper trailer to hopefully somewhat secluded camp sites. These extended mirrors are perfect for my needs. Looking around at what kind of extended mirrors work best, these are consistently rated very high. I would not have any problem ordering from these guys again
