Note: The power remote capability, heated glass, and turn signal of this mirror will work only if your vehicle already has those functions.

This telescoping towing mirror replaces your OEM side-view mirror and provides 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.

Very quick delivery, perfect fit, plug and play, very easy Instalation, looks factory on my 2019 Tundra. Just what the doctor ordered. Thank you for the great service and fantastic product.

They still look like factory mirror’s lov them.
Ben - 06/25/2022


Mirrors came quickly and undamaged. They were well packed.
Dena at etrailer was helpful and professional.
Mirrors are well built. A quality product. I had my local truck
maintenance shop install them. No vibration when driving.
A huge improvement over stock mirrors that I used towing on a
4900 mile trip. These mirrors will make passing 18 wheelers and
other vehicles easier and safer when I’m towing. Money well spent.

Mirrors are holding up well. I do not have vibration problem. When repositioning mirror after pulling in when visiting drive up ATM it doesn’t always index return to home position well. Slight adjustment necessary. Other than that I’m satisfied with them.

2016 Toyota Tundra

I really wanted to like these mirrors. Unfortunately, they are not ones I would recommend. The drivers side mirror shakes constantly while driving (even at low speeds). The passenger side mirror has a weird angle to where it creates a huge blindspot compared to any other mirror I have owned before.


Mirrors have considerable vibration even at low speeds and on smooth roads. I considered returning these mirrors but procrastination got the best of me. However, very easy to install and seem built well.


My mirrors look great and were easy to install thanks to U-tube installation videos. Took less than 20 min per mirror. They shipped super quick.


fit perfectly, match truck.

2017 Toyota Tundra

Great product perfect fit. Simple to install if you look at utube tundra mirror replacement before you start. Would buy from etrailer again.

  • Is the K-Source Towing Mirror # KS70103T an OEM Replacement Mirror for a 2007 Toyota Tundra Limited
    I verified with my contact at K-Source that the Custom Extendable Towing Mirrors, # KS70103T, are OEM replacement towing mirrors for your 2007 Toyota Tundra Limited. This mirror will give you the turn signal, electric and heating functions that your damaged mirror had and uses the factory connections for those functions. This mirror will also have the same footprint as your factory mirror and will use the same mounting points.

  • Does K-Source Custom Extendable Towing Mirror KS70103T have Flat or Convex/Concave Glass
    The top glass on towing mirror # KS70103T is flat meaning it is just like the driver's side, doesn't magnify. The smaller lower glass is convex so the image does have that "objects in mirror are closer than they appear" look to the image. I have included a link to a video review of this mirror for you.

  • Extendable Towing Mirror Recommendation for a 2013 Toyota Tundra
    For a replacement towing mirror that can extend for an increased field of vision I would recommend the K-Source Towing Mirrors part # KS70104T that you referenced. The telescoping arm extends the mirror out from your truck by almost 4" for an expanded field of vision. This heated power mirror also has a built-in turn signal. For the passenger side mirror you would want the part # KS70103T. Or to order them as a pair you would want # KS70103-04T. I attached a review video for you to check...

  • Is There a Difference Between K-Source Towing Mirrors for 2016 Toyota Tundra?
    The only difference between the towing mirrors is that K-Source Custom Extendable Towing Mirror # KS70104T is for the driver's side of a 2016 Toyota Tundra while # KS70103T is for the passenger's side and # KS70103-04T allows you to purchase both at the same time as opposed to individually. These mirrors are a conformed fit for your 2016 Tundra and are power mirrors with heated glass and turn signals on the sides. I've added a link to a video review of the mirrors for you to take a look at.

  • Recommended Custom Towing Mirrors that Retain Blind Spot Indicator on 2016 Toyota Tundra
    I do have an option for you, however the K-Source Custom Extendable Towing Mirror - Passenger # KS70103T (or # KS70103-04T for the pair) referenced in your question will not retain the blind spot detection system on your Toyota Tundra. There is not a custom replacement mirror available that will retain this function. In order to keep this function activated on your truck, I recommend looking at the K-Source Snap & Zap Custom Towing Mirrors # KS81300 as long as you don't have the Limited...

  • Will K-Source Custom Fit Towing Mirrors Fit a 2012 Toyota Tundra CrewMax Platinum

The driver side mirror that you have referenced, # KS70104T, has turn signal, electric adjustment, and heat features. These features will only work if the factory mirrors had the same features.

  • How to Determine if Towing Mirror Turn Signals will Work on a 2010 Toyota Tundra CrewMax SR5 4x4 V8
    We have two towing mirror options for your 2010 Toyota Tundra, I provided links to both for you. The turn signal feature in these mirrors will only work if the connection on your Tundra is factory wired with a turn signal circuit. You can test the connector on your mirror before ordering to be sure that the turn signal function is present. To test the connection, use a circuit tester like part # PTW2993. Attach the alligator clip to a good ground, unplug the factory mirror and probe the...
