    • Push mirrors back into place when you're not towing
  • Power mirror adjustment lets you change mirror face position with the factory control inside your vehicle
  • Heated mirror glass clears frost and ice and reduces fogging

K-Source Towing Mirror Dimensions

Note: The power remote capability, heated glass, and turn signals of these mirrors will work only if your vehicle already has those functions.


These telescoping towing mirrors replace your OEM side-view mirrors and provide the extended view needed for safe towing. Now you can change lanes, merge, and pass other cars with confidence, even with a trailer in tow.


The mirror faces on the custom mirrors can be pulled out to give you an extended field of vision for towing. Simply push the mirrors back for regular use.


The entire housing of each mirror conveniently folds toward your vehicle for easy parking or maneuvering in tight spaces.

This was a fairly easy job, although ripping off the door panels was a little unnerving.
My truck is a 2011 Tundra and had electric/heated mirrors. I was pleasantly surprised that the built in turn signal and running lights now work! Everything was plug and play! Love them!

Fit perfectly on my Toyota Tundra 2019. Everything went as expected. Took less than an hour to install.

Its been a year. No problems with the mirrors. Love them. Would purchase them again for another vehicle should the opportunity arise.

@Russell We're happy to hear that, thank you!


by:

Love these mirrors. Bought them knowing there was no BSM, but didn’t think about the effect it had on safety system. Set off code for BSM and rear cross traffic. The warnings can be turned off in the dash menu but you lose the safety features. These are so much better than the strap-on towing mirrors! Also love the extension. It gives even more view down the passenger side of the travel trailer. Installation was a breeze.

Jim

Still love the mirrors. They are a bit hard to pull out all the way. I have lubricated them to see if that helps.



by:

Product is exactly as expected. Install was simple. All bolts line up with existing holes in vehicle frame. Ensure you apply the weather stripping on the mirror before install. Pictures and videos online are helpful. Side marker lights and turning signal works on mirrors. Great product! Attached are 3 photos.

2015 ToyotaTundra

What a great upgrade for my 2015 Toyota Tundra SR5! Perfect fit. Only took about 15 minutes per mirror to replace them. I didn't have blinkers or clearance lights on my stock mirrors, but these mirrors plugged right in and now I do. I do confess that they are taking me some time to get used to, but I can now see where my tire hits the ground and still have full view of the side of my truck. I can't wait to use them to pull my new travel trailer. I will no longer be a nervous wreck, constantly adjusting my mirrors so that I don't run into something. The biggest problem I see is that I can no longer park in my parking lot at work without getting out of my truck to fold the mirrors in. I'm not certain, but I would guess they add about 4-5 inches width on each side of the truck. I'm ok with that, because these things are a necessity when towing a big trailer. Thanks Etrailer!



by:

These mirrors are high quality. Install easily and added turn signals which the o e m mirors did not provide. Strictly plug and play also. No wiring for me to do.



by:
2018 ToyotaTundra

Easy install. Came with all hardware incase you drop and/or lose the existing hardware while uninstalling OEM mirrors. No shakes or rattles. Top portion is power adjustable, bottom is manual adjust for viewing angles.
My truck is a Limited and has Blind Spot Alert (BSA) & Rear Cross Traffic Alert (RCTA). These 2 features are lost and throw a dash light to see dealer. The warning is annoying, it towing visibility is more important. I'll follow up with my dealer (who actually recommends these mirrors) to see if the dash lights for these 2 systems can be deactivated.



by:
2019 ToyotaTundra

Overall I am happy with the mirrors. Seem to be well built and definitely add more visibility. I have a SR5 and like that it adds the capability of side marker lights and turn signals. Install was very straightforward and had them on in 30 minutes. The curb side mirror is definitely more “zoomed in” than stock because it is not convex but after proper positioning and driving for a week or two you get used to it. My main complaint is that the mirror glass noticeably vibrates with every bump on the road.



by:
ToyotaTundra

Arrived in perfect shape…I was very impressed with the packaging. Easy installation 30 minutes. Even gained turn signals & side running lights. They were put on a2020 Toyota Tundra SR5. I researched mirrors a bit….no one could match the price. I had a question and got a quick Email response.Thanks



by:
2017 ToyotaTundra

I put these on a 2017 Toyota Tundra. I pull a 29 ft travel trailer and couldn't see with the stock mirrors. The mirrors were easy to install. Took 30 mins all together. Was able to put them on by myself. Just like the Description said. The mirrors were packaged nicely also. Plug them in and good to go. Everything works like from factory.



by:

Mirrors look good on truck easy to install. Only thing a is getting use to them over the stock mirrors. So far they seem durable didn’t have mirror maker lights before but with these mirrors my truck has them now.



by:
2008 ToyotaTundra

Received the mirrors in less than 3 days. checked out the video on
utube and on Saturday took me about 30 mins to change out both
mirrors. Mirrors look great and perform outstandingly. The lights and
turn signals work even though the old mirrors did not have that. The
remote positioning works and I would say the defrosters will also (still in the 80's) I have included pictures. Now I can see the back of my camper and should have an easier time backing. Thanks



by:
2010 Toyota Sequoia

The mirrors were delivered in 5 days, and look sharp! Installation was a breeze after watching YouTube videos. I am not a mechanic, and wouldn't have tackled installation had it not been for the videos. The only disappointment was finding out that the mirrors must be folded in manually (like to go through a car wash or other tight space). The original mirrors folded at the push of a button.



by:
2016 ToyotaTundra

Mirrors look great and install was a breeze. It took longer to get door panel off than it did to swap out mirrors.

My only complaint is that the passenger side mirror has a huge increase in how close objects appear to be to the truck compared to OEM mirror, so there is an adjustment period to get use to the mirror.



by:
ToyotaTundra

Fit perfect and look great on my tundra. Side markers work even though my stock mirrors didn't have them. Excellent buy and shipping was incredibly fast. Very pleased

I received the mirrors I ordered and they were easy to install. They look really nice on my truck and I will be using them towing my camper for the first time next week .

Just installed them and they look great, well made , look like they were oem, and received them quickly,have used etrailer several times and so far they don’t disappoint.

2017 ToyotaTundra

2017 Tundra. Broke the OEM right side mirror being careless. Really needed tow mirrors anyway, so changed them both out. MUCH better for towing our camper and enclosed cargo trailer. Fit perfectly. Watched a couple of people replace these on YouTube. Easy project. They are notably bigger than the OEM shorty mirrors, but that's kind of the point. They look very similar to the OEM extendables on quite a few makes of truck so they don't look odd when not towing. Truck still fits through 10' wide garage door with no problem. Really tight on 9' garage door without folding either if their not extended but does fit (barely). Folding the left side and leaving the right in the retracted position, it fits through the 9' door just fine. Exactly what I needed.

After a year, still working perfectly. Extendable towing mirrors is something I should have had on all the trucks I ever ever used to tow anything bigger than a Jon boat.



by:
2015 ToyotaTundra

Received K-Source Custom Extendable Towing Mirrors for my dark gray 2015 Tundra as expected. I had a bit of trouble getting the driver side OEM mirror removed as the center locating peg would not let go. Past that everything went together smoothly with only small adjustments to align the brackets with the door trim. Mirrors and lights worked as expected. Road test proved vision to sides and rear of trailer were greatly improved. Definitely, liked the addition of the blind spot mirrors...

I just purchased these mirrors. Took 30 mins to install. Really simple. Happy with the purchase. I tow a 29ft travel trailer



by:

Have had great luck with these mirrors. Tried many slip on and clip on towing mirrors but none stayed put (several actually blew off going down the road). Finally bit the bullet and purchased these total replacement mirrors. They fit like the OEM mirrors.

Mark

Mirrors are still working great! Still one of the best upgrades I have made.



by:
2015 ToyotaTundra

The mirrors arrived well packaged and with no instructions. Following easily found YouTube vid, installation was easy taking around 15 minutes per mirror. The mirrors are good quality. On my 2010 Tundra the signal, heat, and adjust features all function fine though my OEM mirrors did not have the signal feature. The driver's side mirror produces a whistle when the vehicle is moving faster than around 45 mph. I hope to fix that with a piece of duct tape... without the whistle they'd get that fifth star from me.

Randy

Where on youtube did you find the installation procedure?

Todd V.

8/29/2013

Uh, a Google search for replace tundra mirror produces two videos among the top ten search results. Both videos where helpful. The mirror replacement is straight forward. Pulling the door interior off takes a bit of force. I hadnt done it before so didnt know quite how hard to pull. Start at the bottom as in the video, lift up and outward. There are still some wires attached so have something to set it on, or someone to hold it.

  • Towing Mirrors Compatible With Blind Spot Monitoring System On a 2020 Toyota Tundra
    I recommend using the K-Source Snap & Zap Custom Towing Mirrors # KS81300 on your 2020 Toyota Tundra with the Blind Spot Monitoring indicator in the mirror. The K-Source Custom Extendable Towing Mirrors # KS70103-04T you were looking at do not have the indicators for the BSM system.

  • Towing Mirror Recommendation for a 2010 Toyota Tundra SR5
    The K-Source Towing Mirrors part # KS70103-04T are confirmed to work on your 2010 Toyota Tundra SR5. You will retain all of the functions your factory mirror had, but won't gain any that weren't there to begin with.

  • Will The K-Source Custom Extendable Towing Mirrors Part # KS70103-04T Add Turn Signals
    The K-Source Custom Extendable Towing Mirrors part # KS70103-04T will retain all factory features of the current mirrors on your 2013 Toyota Tundra, however, will not add any new features that are not already equipped. Therefore, no, if your current factory mirrors did not come with turn signals, then the K-Source mirrors will not allow you to access this feature although they will still retain the heated and power functions.

  • How to Fix Extending Towing Mirrors for 2015 Toyota Tundra
    I checked with K-Source on the K-Source Custom Extendable Towing Mirrors part # KS70103-04T for your 2015 Toyota Tundra but there are unfortunately not any maintenance procedures. I'd recommend using some spray lubricate to free the slide mechanism and then some grease to prevent it from sticking again. If this does not work, best option would be to replace the mirror, part # KS70103T for passenger or part # KS70104T for driver.

  • Do the K-Source Custom Extendable Towing Mirrors Fit a 2020 Toyota Tundra?
    Yes, they will. The K-Source Custom Extendable Towing Mirrors item # KS70103-04T will fit your 2020 Toyota Tundra. These mirrors are custom fit and designed to replace your factory mirrors. I have linked an installation video below. One thing to note is that we have spoken to K-Source and you cannot upgrade to a power mirror with heated face and turn signal if your OEM mirror is not already equipped with those functions. It will fit but you won't gain the two functions.
