K-Source Snap-On Mirror for Ford F150

Note: These snap-on towing mirrors will not fit OEM extendable mirrors.


With these towing mirrors, you get a guaranteed fit and seamless OEM style. Tools and other hardware aren't needed for installation, and the secure, snap-on fit means there's no danger of losing these mirrors on the side of the road. Attach them by simply popping them over the backs of your existing mirrors. The built-in clips on the towing mirrors will grab the inside edges of your factory mirrors for a secure fit. These mirrors are customized for your vehicle, helping to prevent vibration or excessive wind noise. You'll be ready to travel in seconds, and the increased field of vision will allow you to cruise the highways stress-free.


These towing mirrors are custom designed to match the contours of your factory mirrors, and they let you retain use of the features on your factory mirrors. Cutouts in the towing mirrors line up with the turn signals, puddle lamps, and BSDS camera on your factory mirrors. And a clear panel on each towing mirror allows the LED spotlights on your factory mirrors to shine through. The add-on mirrors will not obstruct the factory mirror faces, and they will not interfere with adjustments to your factory mirrors.

Perfect fit on my 2018 f150. Took about ten seconds each to install. No vibration while driving. The mirror is small but I can see down the side of my travel trailer. I would recommend this to a friend.

Its been a year since I bought the mirrors. They work great, easy on and off when not using them. Id buy them again and would recommend them to anyone...



by:

The mirrors came sooner than expected which made me very happy. The fitment was spot on, had them on in about 2 minutes. Another few minutes for applying Armorall and aligning the mirrors. Now I'm good to go with my 26ft camper trailer.

These mirrors are economical and a must for increased rear view when driving and backing my 26ft camper. Glad to have them!



by:

I have used these mirrors when pulling my 30’ trailer. This is a fantastic product, very easy to use, stays on perfectly, fits right over factory mirrors, felt on the inside allows for no scratches or worries. Easy snap on snap off, stowage in small felt bag. Mirrors adjust very easy. Great product, I would definitely buy again.

They take some effort to install, but I got it now. They are very tight and easy to use!

I just purchased a new travel trailer and did not really know what I would need for mirrors, I purchased these snap on mirrors (kind of a goofy name "Snap & Zap"!). They worked perfectly. I can see all the way down the side of the trailer and the traffic that is behind me. I have a 2015 F150 and these extension mirrors snap on and off easily and fit very snugly. The mirrors don't vibrate and they hold their adjustment. A bonus is the bag that the mirrors come in, it is divided into two sections so the mirrors are not banging into each other when storing them. So far they seem to be a great product and get the job done for me. I would recommend these to others.

hard to tell it is an add on. looks like factory mirrors. very happy with this product!

The mirrors are a great addition to my new truck. They look very good and fit like a good set of gloves. I am sure they will do a fine job for us in our travels. Everyone at Etrailer is a pleasure to deal with and very helpful.thank you very much.

The mirrors are working just fine .Couldnt be happier. Thanks for a fantastic product.



by:

These mirrors are awesome! My trailer is 8 feet wide, 29 feet long. The mirrors now measure 8 feet 7.25 inches wide tip to tip with the new extensions. Extending my view 3.6 inches on each side. They don't vibrate. And the mirror blinker lights are clearly visible through the attaching mirrors. They have the appearance like factory equipment. Used mine on numerous trips now. I don't normally do reviews, but I'm really pleased with these! You won't be dissappointed.



by:

10 seconds to put on and they look like factory stock: they enable me to see well beyond the side of my fat toy box
Cheaper than buying new mirrors from Ford !
I would definitely recommend!
Thank you for solving my trailer, towing and truck needs as usual !

Super works great



by:

I have owned the K-Source zap and snap tow mirrors for 1 year. I had purchased an RV trailer and was in need of tow mirrors. I stumbled across these mirrors while searching the internet and decided to purchase them. The mirrors were as expected and quality excellent. While towing, the mirrors are very solid with no movement, as if a permanent mount from the factory. It takes approximately a few seconds to install and uninstall. Best tow mirror on the market with an affordable price. I would highly recommend for purchase.



by:

Easy installation and removal and great product



by:

They fit my truck mirrors perfectly. Haven’t had a chance to actually use them on the road yet, but I feel like they will work. Pulling an enclosed 8.5 x 16 car hauler and just need that little extra.



by:

The product does exactly what I needed it to do.

It gives me that extra view to see outside the trailer.

It also saved me $800 per mirror since I was considering upgrading to Ford extending mirrors. These were perfect and saved me $1500

Would recommend to anyone needing that extra range of view. They also pop on and off easily, but are secure when in place

I loved the mirrors when i had them on my truck. I sold them to another Ford F-150 owner and he loved them. I no longer needed them since i sold my F-150 and purchased a New Ford F-250 Diesel with automatic extending mirrors

Can only comment on the fitment-very good. Will put them to the test this weekend on a trip.

These are the best aftermarket towing mirrors I have ever had!! Easy to install, less than a minute for both sides, worth the money, no shaking!!



by:

Bought a new Ford truck and was unable to find towing mirrors locally to fit a new vehicle. Thanks for having the latest products. Mirrors fit well and look really good. The clear area allows the turn signals to shine through so others can see the signal. We tow a 25 foot camper and some farm trailers. These mirrors will increase safety on the road and for parking. Nice of you to follow up to be sure we were happy with the product.

The truck mirrors have held up well and we are still very satisfied with the way they look and the ease of installation. Great product.



by:

My 2018 F-150 pickup has the major features I wanted: V8, 4x4, 8 ft bed and extended cab. The factory side mirrors are standard so longer trailers obstruct the view. Since it's rare that I tow such a trailer, installing replacement mirrors wasn't needed.

Instead I searched the web for temporary mirror extensions. Etrailer.com had a great selection and I was able to purchase a set and arrange timely delivery.

Within 5 minutes I had them installed. Fit was perfect and they look great.

@David That's awesome, David! I'm glad they are working as intended. I may need to get some for my 2017 Titan since it doesn't have the factory tow mirrors :/


by:

They snap on and off easily without damaging the truck. The added view helps greatly. The mirrors fit well and don't vibrate or shake giving a clear view.



by:

From ordering, my mirror extenders to receiving and then installing them on my mirrors was a breeze. I would recommend these to anyone. The service was great and it felt very personalized. Thank you Snap & Zap!

  • Do CIPA Custom Towing Mirrors for 2016 Ford F-150 Lariat Have Flat Glass
    Hello Fred; the CIPA # CM11551 or # CM11550 for the pair do not have flat glass but they are compatible with the Lariat model. If you would like to have flat glass I recommend the K-Source Snap & Zap Custom Towing Mirrors # KS81850. The only reason these won't fit your 2016 F-150 is if you have extendable or telescoping mirrors.

  • Differences Between Snap-On And Slip-On Tow Mirror Extensions
    The K-Source Snap & Zap Custom Towing Mirrors part # KS81850 are snap on side mirror extensions whereas the CIPA Custom Towing Mirrors part # CM11550 are slip on. The difference between the snap and slip options are as follows: The snap on mirrors will provide a much more secure fitment around your factory mirror however, the tighter fit could cause more wear to the mounting surface. The slip on mirrors will prove to be a less secure fitment and will reduce the chance of surface scratches....

    The K-Source Snap & Zap Custom Towing Mirrors part # KS81850 are a confirmed fit for your 2017 Ford F-150 and will work well for you. The main reason I like these mirror over their competitors is that the glass is replaceable using part # KS81852GLH for the driver and part # KS81851GRH for the passenger side should anything happen. As far as the "focal length" issue you are referring to goes. All modern passenger and commercial vehicles here in the U.S.A. have a passenger side mirror with...

    Although we don't offer a custom towing mirror option for your 2022 Toyota Tacoma, we do offer universal fit options that would work great for you.

The ratcheting straps allow for a very tight fit to the factory mirror housing which minimizes vibration and ensures the mirrors will stay in place. I'd recommend the # KS3990 Dual Lens Towing Mirrors. The dual mirrors allow for...
