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.

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.

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



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.

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

Same as my old mirrors easy install

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



by:

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:

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...

Fantastic . The mirrors are perfect for trips where I am pulling my 20’ Duckworth boat. It makes the blind spots viewable. When not pulling boat they slide back to normal position within seconds. Very flexible!

@Dan Glad we had the right fit for keeping you safely towing your boat to the water Dan! What body of water do you mainly go out on? I have a Ranger and am out on the Lake of the Ozarks a lot here in Missouri, although the summer months you can mainly find me on Mark Twain Lake. The big wakes are little too much for us in the summer months at the Ozarks!! As long as the boat ramps aren't frozen over we are going out!!


by:

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:

These are excellent mirrors. I would buy them again in a heartbeat. Fairly simple to put on, but takes time. They look like factory mirrors.



by:

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.



by:

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 .



by:

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



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:

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:

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:

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:

Fast accurate service!



by:

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:

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.



by:

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!

Great product. Installed easily. Works as advertised.

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!

Very easy install. All functions work even the running lights and turn signals which my factory mirrors didn't have. Will update review after first camping trip to see how they perform with the travel trailer. Installed on 2021 Tundra.



by:

The mirrors look and fit awesome. i got an added bonus as my 08 Tundra was not supposed to be wired for turn signals. Well I ended up with heated,power marker lights and signals. all is good except fot the broken top corner on the PS. found part in box and glued it. chalk this up to shipping handling.

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.
