Video Transcript for Set up: K-Source Universal Towing Mirror on a 2021 Ford Ranger

Hey everybody, Clayton here at etrailer.com. Today, we're gonna be checking out the K-Source clip-on towing mirrors on our 2021 Ford Ranger. Adding a towing mirror to your ranger is really gonna increase your visibility whenever you're towing, because we want to see whatever we have behind us, and this is gonna be a great way to do it, because whenever we need it, we simply just throw it on our vehicle and when we're done with it, just take it right back off. Now we're gonna have a plastic framework that runs around the outside of our mirror. We're gonna have two hooks that actually grab onto that frame, to keep it nice and secure. One thing I do like about this is how easy they are to take on and off.

And they're pretty easy to get set up. And with them being universal, they're more than likely gonna work on another vehicle that you own. Then adjusting our mirror is gonna be super simple. We just adjust this outside, and actually this one is pretty tight, so that's good because once you adjust it you're not gonna have to worry about it moving, whenever you're going down the road. Our towing mirror is gonna fasten to our factory mirror with these rubber straps, so it's gonna be super easy to adjust, whether you need it tighter or looser.

As you can see there's notches here on the back and that's how you're gonna either loosen it or tighten it, depending on how you want it to fit. Now, one good thing about there being two straps is it's gonna keep it from sliding around whenever we are going down the road. As you can see it is pretty firm. Another nice feature of this mirror is we're still gonna be able to use our side marker lights, and our puddle light underneath. So everybody is gonna be able to know what we're doing, and we're still gonna be able to see whenever we get out of our vehicle at night.

And when it comes time to install these, you're just gonna grab your clips, line it up onto your mirror, then you can grab the strap on the other side, run it around, and just hook it in on the top there. Repeat the same steps on the other side. And then you can come back and tighten it down to make sure it's not gonna go anywhere. In conclusion, adding towing mirrors is gonna be a great way to tow safely, and doing it this way is a lot better than installing something permanently, because it's not gonna be there when we don't need it. Now, today we are looking at the two part kit, so that's gonna be one mirror for each side, but you can also just find one singular mirror, if you only want one on the driver's side, here at E-trailer.

And we do have some other options here at E-trailer. We have some that have dual mirrors on the outside, so you're gonna actually see a little bit more. But some of them do install a little bit differently, so feel free to check them out here at E-trailer, using our fit guide. And that's gonna do it for our look at the K-Source clip-on towing mirrors on our 2021 Ford ranger..

Arrived a day early excellent quality
by:
Having tried a couple of other clip on mirrors, which fell off while driving at highway speeds, this one was super easy to put on and stayed put!! A simple design that works!
by:
This is a VERY Good "universal" tow mirror set. The non-slip rubber straps do help hold them in place. However, after a bit of time they will slide some and will require some re-adjustment and/or tightening (hence 4 Stars).

I've had them on 2 different shaped mirrors and worked equally well. I highly recommend for those applications where a "custom fit" set are not available.
by:
I bought
the biggest ones I could find for the mirrors that I have
. they just barely would fit over the mirrors.to be honestthe quality of the mirror itself was not great.it was a little blurry and shakes a lot.guess I expected to much from them.to be fair if you have or know of a better one with a clearer mirror I would purchase it.thanks for letting me vent a little.

You know I checked and I do not have a different towing mirror that would be better for your 2015 Ford 250. I wish that I did.

by:
Looks very well made and came quick. They will make it possible for me to be able to back up my trailer as I will be able to see to the back. How well they fit and perform will have to wait till spring. Too cold right now.
by:
The mirrors do vibrate quite a bit on rougher roads making them difficult to use.
by:
They work great

Excellent product and customer service. These mirrors are what you need when towing long trailers and you need to see both sides full length.

After a year in use these mirrors are still great. No cloudiness, discoloration, etc. Couldn’t be happier.

@Sheila That's good to hear, Sheila! Thanks for your feedback :)
by:
The mirrors attach ok, but block about an inch of my truck mirror. Mirrors appear absolutely flat, so u dont see much in the small mirror. For all the trouble of attaching, adjusting, not to mention its just another step when hitching up, they don't provide any improved rear/side view. As a retired fire safety officer, former fire truck driver I am disappointed. I had big hopes.
by:
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.

Choosing the straps to be able to avoid the cameras is brilliant! I'd love to know how you like them once you get a chance to tow with them, too :)

by:
These work much better than these type of tow mirrors decades ago. I wish Toyota still had tow mirrors on their tow packages! This is acceptable, but not as good as they should be. I had to buy two when I only needed one—I can't blame that on K-Source.
by:
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.

These mirrors continue to work very well. Minimal vibration, easy attachment. Recent 2,100 mile trip with no problems. Interstates, trucks passing, two way country roads all no problem. Excellent value for the price. PRO TIP - #1 No need to unclamp the straps, once adjusted just stretch them over your car mirror. #2 Label the mirror with a sharpie so that you know which is drivers side since they are identical. #3 Check snuggness of straps periodically.

by:
Only work on rectangular mirrors. My mirrors have a taper on the bottom the clamp is not secure. I will have to try and heat and bend the lower bracket.
by:
The mirror can not be used on an Audi Q5.
IIt's rear mirrow has a much to conical shape. So your towing mirrors are falling off after just a few miles driving.
by:
They get the job done. I see both sides of my camper. A little vibration is present at speeds above 40, but not excessive. The mounts fit well on the bottom of my vehicle mirrors, but interfere at the top - pushing them a little out of alignment, but still useable.
by:
BUYER BEWARE!!!!!!

I had great hopes for these mirrors. They look great. They appear to be very adjustable right out package. They fit on my Tacoma securely. They don't interfere with the function of the stock mirrors. Everything was moving along "swimmingly".

Then I sit inside my truck to do the final adjustment (moving the actual mirror to get the correct setting and lock it into the "sweet spot"). The new Mirror is very stiff...doesn't want to move. Well, its new...so....Okay, I don't want to ruin anything...so....

No worries, I go get a phillips screwdriver to loosen the back screw a smidge so the friction adjustment can work . Come back start to back the screw out just a smidge...nope...still can't adjust the...wait...unscrew some more....that's not an adjustment screw at all. That just screws directly into the back of the mirror to hold it solidly in place. Worse yet, There is no friction mechanism on the back of the mirror at all. It is one solid piece of plastic. The molded plastic replicates the look as if it has the ability to move, but in reality....There is no way to do small mirror corrections once you have this thing installed.

What the Actual people?????!!!!!!???? If you can't do minor adjustments to the mirror while you are in the vehicle, then the mirror is completely useless. I wouldn't recommend this product to my worst enemy. It's a piece of crap. DO NOT BUY!!!!

A complete waste of time, money, and shipping costs. Now, I have to incur more shipping costs to send this POS back to etrailer.

Hey, etrailer....Do Better next time!!!!
by:
After using these mirrors to tow my 27 ft. Travel trailer I found them to be somewhat useful. A small improvement but didn't provide the significant improvement I was expecting.

As noted in my original assessment this product is marginally useful. I would not buy this product again. It works but not great and not worth the price. Used on 2022 Tundra SR5 towing travel trailer.

@Alejandro I am sorry that you did not like the mirrors better Alejandro. I only recommend the universal fit mirrors if there is not a custom fit option. If you do not have the telescoping mirrors, the K-Source Snap & Zap Custom Towing Mirrors - Snap On - Driver and Passenger Side # KS48NQ would be a better option.
by:
Would prefer a more custom fit
by:
I am going to return them. Really dont help as inside mirror has to be positioned a certian way in order for clips to fit.
by:
I like the mirrors, they seem to be a good fit for my 2014 Honda Ridgeline. I was not pleased to see the same mirrors on another site for $[XX] less, however being guaranteed to fit has value.
by:
A little difficult to adjust, but does the trick.
by:
Fits really well on our Hona Ridgeline
by:
They don’t fit well, and I have not used them. In fact I forgot n even have them.
by:
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.
