Nice upgrade to my truck
Soooo much better than the OEM tow mirrors on my 2008 Ram 2500. They fit very nicely, install easily and look great. Running the wires to make the lights work was a little time consuming but totally worth it. I tied the white puddle lamps and white backup lamps together and triggered them with my dome light circuit so they all come on when I hit the unlock button on the keyless entry remote. The blind spot mirror is shaped much better than the original mirrors and makes backing up trailers a lot easier. I get a lot of strange looks from other Ram owners and questions in parking lots occasionally from guys wanting to know where I got them or how I made Chevy mirrors fit a Ram lol. They are a huge upgrade from the original dumbo mirrors and I am very glad I bought them.

K-Source 70103-04T Towing Mirror Pair for Toyota Tundra
I recently purchased the K-Source 70103-04T Towing Mirror Pair for my Toyota Tundra, and I’m thoroughly impressed with the product. First off, the packaging was excellent—everything was securely packaged, ensuring that the mirrors arrived in perfect condition. The installation process was straightforward and easy to follow. The mirrors fit perfectly on my Tundra, and I was pleasantly surprised by the quality of the fit and finish. It exceeded my expectations, making them look like they were factory-installed. Overall, these towing mirrors are a great addition to my vehicle. They’re sturdy, functional, and enhance the overall appearance of my truck. Highly recommended for anyone looking to upgrade their towing setup.

If you are towing, these are the way to go.
These mirrors are already further out from the truck when installed than the original side views. Add to that the fact that you can pull them out further, that you now have bottom convex mirror, the top mirror is powered with a wide range of adjustment, and they are EXCELLENT. These are very easy to install. Look for a video on youtube. One clip is not well explained in video. On the inside door panel, just below the mirror, there is a button/rivet, that you need to push the center in. When reinstalling, pull the center pin out further than original and then press it back to flush. You only need to lower the door panel a couple of inches so having something below the door to support it, keeps it from pulling on control lines. Not necessary, as shown in the video, but helpful. There is also a plastic pin, used in production , that needs to be removed after you remove the factory mirrors and before you install these. I noticed on some other reviews, that other, cheaper products, appear to have convex mirrors on the bottom but reviewers complained, after they received them, that it is only a second flat mirror. These have convex mirrors on the bottom, which is manually adjustable. Also these do manually fold in. . These are a little pricey, but by next year I will have forgotten how much I actually spent. I would definity recommend these if you have a Toyota Tundra and are towing a camper or fifth wheel. Mine is a 2016. From what I see on the box, I believe these fit from 2007 on up. PS: (oct 2016) I should have mentioned that these are also heated!

Fits 2019 Toyota Tundra Limited
Installation errors I learned: 1. When I removed my stock mirrors, there was a small black pin sticking out of the door that went inside of the stock mirrors. These new mirrors do not have a hole to fit the small black pin and I had to cut the pin off. It didnt really seem to serve any purpose anyways. 2. When I first installed the driver’s side, I did not know there were new bolts already on the 3 bolts because they are hidden under the waterproofing seal. Make sure you remove the new bolts from the new mirrors before installing. 3. After I installed the mirrors, I went to put the door panel back on and it kept popping out at the top. I learned the top of the door panel is a piece of velvet like material that is supposed to touch the window. When you reinstall the door panel, the top of the door panel needs to be over top of the metal door frame and it kinda hangs on it until you clip it all in. 4. When you take the door panel off, some off the white clips might come out of the door panel and stay in the metal door frame. Make sure you take those white clips out of the door frame and slide them back onto the door panel. 5. The bolts are 10MM, however the bolts are very long and my standard 10MM socket wasnt long enough. Make sure you have an extended 10MM socket. 6. I wish I put loctite on the bolts. 7. Use the box it is shipped into set the door panel on Review of the product: Definitely easier to tow my big boat and see behind me now. These mirrors are much larger than the originals however the original ones seem to show more in the mirror. I believe this is because the originals are (for lack of a better term) zoomed out, like convex mirrors. These new mirrors seem to be a standard mirror like in your bathroom, it does not magnify or demagnify. The new mirrors do have a nice big convex mirror at the bottom. The power heating works and power mirror works. The convex mirror is manual as well as extending the mirrors out and folding them in. The running lights on the side work and the blinkers on the side work. Installation was quick but a pain in the ass. The mirrors help me tow my boat and see whats behind me. New turn signals and running lights on the side are nice. These are big and beefy looking too. I would buy again.

Awesome Tow Mirrors!
Awesome mirrors! I was able to install in under an hour...without watching the instructional video online....I am my fathers daughter after all! Pretty self explanatory. All the functions work! Including the ones that weren't on the original mirrors. For some reason Toyota doesn't put directionals on their mirrors yet they are hard wired to accommodate?? Very nice to have the directionals on the mirror. I installed these on a 2015 Tundra SR5 TRD Off Road. I have noticed at speeds over 70- there is some vibration of the mirror that others have spoken about but not enough to complain really. Also someone complained the smaller convex mirror is fixed- maybe they didn't push hard enough?? I was able to adjust them perfectly. Glad I didn't purchase the Toyota OEM towing mirrors for $600! There was some confusion with my order. I received a single mirror on Wednesday (at 4:30 pm)...clearly a set means 2! I called and explained the mistake. Amazon had the mirror set delivered to me by Thursday afternoon!! Very impressed! And the new box that arrived clearly stated a set and not to be separated! So I guess I got a miss pick!

Great Product
Traded in my old Tundra for a newer one and I really wanted the trailer mirrors like I had on my last Tundra. Found them and I didn't get ripped off in the process. I have had them for about three months now. These are VERY easy to install...about 15-20 mins each side like the previous post mentioned. They look AWESOME(as expected) and really give my 2012 Tundra the wide stance that complements its leveling kit. The power mirror option works, the lights on the sides work, and the turn signal lights work as well...exactly like the factory lights. The mirrors are very sturdy and seem to be made of the same materials as the factory mirrors. The only issue is that I think the magnification on the passenger side mirrors is a little off. Not enough to cause a problem, it just took a little getting used to... Overall, a great buy!

Mirrors are not Convex! Reduced Visibility
Do not buy these mirrors if you want to see what's behind you. Bought the pair, and installed the passenger side mirror. Installation was fairly easy (search for the YouTube video). Everything worked as it should: Blinkers, adjustment, heat. But when I sat in drivers seat to adjust, I noticed field if view is greatly reduced. It does not have the "objects in mirror may be closer than they appear" warning, meaning it's not a convex mirror. I can't see nearly as much as I can with the original factory sports mirror. Same issue with drivers side mirror, but luckily I didn't install that one. Returning to Amazon.

Great Quality, Easy Install, Looks Fantastic
I bought these for my 2014 Toyota Tundra SR5. They fit perfectly, were easy to install with the help of YouTube and figuring it out. First one took about 30-45 min and the second one only took 15 min. They look fantastic, havent noticed any shaking and the entire product seems to be extremely well made. The lights on the side work, they're heated, and the top mirrors move perfectly with the controls. The bottom mirrors move by pushing them how you want them and the extension works great by simply pulling them. Didn't break any of the clips during the install.

Perfect replacement
Once I figured out how to get the first door panel off, it was a cinch. Only thing I had trouble with was the plastic retainer pin. It looks like there is a hole for it in the base plate of the mirrors (same as the OEM mirrors) but there isn’t. Solution: use a philips screwdriver from the inside to punch the plastic tab out of the door, now the mirror bolts fit perfect and the base plate fits flush. As for the mirrors, they seem heavy duty, signal and electric mirror adjust works well. Does not have internal motor so the folding mirror button on my 2013 tundra platinum no longer works. Overall it looks like it will be a good upgrade!

Great mirrors, easy to install and big improvement for my truck.

Perfect fit
These mirrors worked great. The only thing that you need to know when installing is it comes with new nuts on the bolts on the mirrors. They replace the original nuts. Nothing is said in the instructions to remove them.

Not bad, but not great
These things were a snap to install and they look great. My only real beef is that the passenger mirror is like a telescope. Its magnification is really bad. A vehicle that is like 20' behind you looks like it's riding your bumper. There is also a little bit of vibration in both driver and passenger mirrors but nothing terrible.
