Most Popular Manual for GMC Sierra

Simply installed and removed, these mirrors make all the difference when towing our 33’ trailer. They easily adjust to allow the best views of both the trailer and surrounding traffic. I highly recommend this product.

These mirrors are GREAT!! Exactly what I've been looking for. The fit, adjustability, look are awesome!! They look like they are factory installed. We tow a travel trailer (now with a 2011 Suburban) and vision from the passenger side has always been a problem. I have tried others from different sources on different tow vehicles: there is no comparison and they are cheaper too!! I am so glad I found etrailer.com. Just plug in your info and the solution to your problem is found!

I have 2 mid 2000’s model GM trucks. I’ve been looking for towing mirrors that wouldn’t break the bank and not look like ford mirrors slapped on them. I also did not want to lose the puddle lamps and auto fold function in one of them. These mirrors fit the bill. A little difficult to install in the cold, but a fabulous OE look and fit. I’m excited to see if they actually provide the sight lines I’m hoping for.

Nice mirror extensions! Look good on my 2003 Chevy duramax diesel. Perfect fit and very easy installation!! I have an overhead camper on my truck and this will sure prevent an accident changing lanes now with these on. I will take them off when l’m not camping. Easy to do. I live in the low desert where we get extremely hot during the summer and the heat could possibly weaken the plastic? I don’t want to ruin them.

I guess you get what you pay for. They were easy to install on my Tahoe. The driver side works well as I can see behind my Travel trailer. The passenger side just doesn't work for me. Its a flat mirror (Not convex) so field of view is very limited, I just cant find the right position for it. I also find it a bit confusing as there are now 4 different mirrors to focus on. I think the ultimate solution are the larger telescoping units. But of course they cost more and installation is more involved. I don't trailer that much so I can live with these. Oh, one little annoying thing is they whistle when the window is down(Quiet when the windows are up). I think its the sharp edge. On the plus side removal is quick so when you don't need them they come off easily when not needed.

One of the best products I’ve bought in a long time. Fit perfect and was exactly as described!

I have a 2000 Silverado 2500 and the CIPA towing mirrors fit perfectly. I took my time putting them on as suggest by over Product Reviews, and did not have a problem.

Good afternoon, i received the Custom Towing Mirrors the other day and they arrived unharmed. When i looked at each mirror i recognized that the plastic portion of the mirror was injected molded, that is not a bad thing. But having over twenty-five years of injection molding experience i have to wonder and question the manufacturer’s quality inspection system. The flaw that i see is on both mirrors because it is the point or ‘gate’ as it is known in the business, where the molten plastic comes into the mold to fill the cavity. In each case the area is marred by what is known as ‘splay’, which by no means lessens the functionality, but does take away from the beauty of the finished product. Quality control should have never let these items out of their hands, unless of course they really do not give a hoot! i do think your products are worthy of better presentation. Thank you for your time. john M. of DE

Delivery was quick. The mirrors slipped on with ease and fit well over the existing mirrors and looked almost factory attached. Then came the task for securing the attachments to the vehicle. While the concept is easy someone forgot to check deminsions of the parts and were to short to work on my vehicle. I contacted etrailer by chat and asked if there were alternatives for securing the mirrors and unfortunately there weren't any. Then came my decision to use heavy duty electrical looped through the hole the sent hardware was to be inserted through. Unless you look closely they are not easily seen. When I want to remove the mirrors I simply snip the cable tie on each mirror and ues new ones the next time I need to use the mirrors. While my "fix" works they only 3 star because to the attachment hardware.

The extensions fit the mirror but the hardware to hold them on won’t work. I’ll have to make hardware for them to work properly.

Great mirrors, very pleased with them!

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

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

The slip-on mirrors that I ordered fit snugly over the existing mirrors. As a Canadian, I was a bit anxious about ordering the mirrors from an American company in case they didn't fit, however your videos and sizing according to the vehicle year, and model made it reassuring that the product would work. I'm really happy with the mirrors, and look forward to using them for many years to come.

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

this is the second set I have purchased this summer (traded trucks). mirrors do a great job of improving the rear vision of trailer. Gets out and beyond the camper. Both sets function great the second pair the finish had some minor inperfections but they are after all temporary mirrors. I would buy rhem again. Great price for great reults. I also parked truck in the hot sun and put a cord around mirrors just to form it tighter to my mirrors on second set not needed, just me

These mirrors look like they will probably work for towing my trailer. They vibrate pretty bad, and the mirror is not convex at all, so you don't see much, especially when it is vibrating. If you get a 4x5.5 blind spot mirror, it helps alot, and you don't notice the vibrating. Then you take a heat gun, and heat up the inner top corner of the housing, and reshape it so it fits tighter, it makes it better. The mirrors are pretty ugly too, I'm glad they go on and off easy.

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 bought the towing mirror to replace one that got damaged. I like the mirror and was pleased that I found the replacement at etrailer.com. The site was easy to use and the order was quickly filled.

This was exactly the mirror I was looking for to match the existing Driver's side. The product has been improved since my last one which blew off from being loose anyhow while this one is engineered better and gives a good view of the blind side of the trailer and right lane. Good for corners and space back ins!!

Not made for a sprinter van. Returning

Exceeded expectations as a add on to the factory mirrors for both a Chevy Silverado truck and a Ford F150. It appears the extension is a perfect match and functional solution for trailer towing without the expenditure of new mirrors. Etrailer was not only the greatest value for this product from any internet site or regional store supply, but they also beat their date of delivery by six days on a UPS business delivery. I will definetly use etrailer for future purchases!!

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.)

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.

ordering was easy. the product was delivered quickly and without damage. I have a 2023 Colorado Z71 and was concerned about how the towing mirrors were going to attach to the tapered factory mirrors. the fit is superb. no movement during use so far.. I would recommend these to a friend.

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.

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.

The good: inexpensive; decent quality materials The bad: doesn't hold it position very well during extensive or high speed travel - you have to readjust at nearly every stop for gas on a trip. Conclusion: It is worth the money due to its fair price.

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.

Mirrors work exactly as intended, greatly improving rear vision when towing our pontoon behind our 2014 Tacoma. Store nicely in the compartment under the rear seat.

Excellent product. Easy to put on. Took them off, put them in my camper storage. Next trip out, when I put them on, I did not even need to adjust them! The mirrors are slight contour and slight magnification, which makes them easy to see. There is virtually NO vibration during travel. (I have had others that shimmied so bad you could not see a thing.) I flip my driver side mirror in frequently to check my mail box, so it is not very stiff. So I ran a small bungee from the clamp to the grill under my hood. Did this for both sides. My driver side flipped in when traveling at interstate speeds, so I put a second bungee on it. Fixed the problem. Allen bolts at top of clamp are rusting after 2nd use. All in all though, I am very pleased with this product and it is well worth the money spent. It is the only product I could find to properly fit my 2011 Toyota Tacoma, because it clamps on the mirror frame and does not rest on my truck mirrors. Great Product!

They are fine for the price but hard to adjust the mirror itself after installation. I’ll be installing the bigger factory trailer mirrors pretty soon.

They appear to be as advertised, well made and should be easy to install. That may change once the rain stops and I am able to actually install them and then use them during the towing operation of our trailer. But i feel pretty confident they will be very helpful.

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
