Extra-large, universal towing mirror clips over one of your existing side mirrors to give you an extended rear view. A ratcheting strap system creates a snug fit to reduce vibration. Works on driver- or passenger-side mirror. Tool-free installation.

Specs:
This adjustable, universal-fit towing mirror expands your field of vision so you can better see your trailer or anything else that is behind you. The ratcheting strap system gives you a snug fit that reduces mirror vibration. Because the mirror arms adjust into several shapes, it can be attached to either the driver's-side or passenger's-side mirror on a variety of vehicles. Each of the mirror's mounting arms is jointed behind the mirror so the arms pivot inward or outward, and 2 additional joints in the middle of each arm add further adjustability so you get the perfect fit.
Built-in clips on the arms will grab the lip between the glass on your factory mirror and the factory housing. These clips are also adjustable to fit the thickness of your mirror housing.
The ratcheting system uses heavy-duty rubber straps to tighten the towing mirror securely over your existing mirror. A quick-release button in the middle of the ratchet lever allows you to unlock the ratchet mechanism for fast strap adjustment or easy removal of the mirror. When you install the towing mirror, use the ratchet lever to tighten the straps. When you have the straps securely on your mirror, close the ratchet covers over the ratchets to lock them in place.
A ball joint behind the mirror allows you to manually adjust the mirror face to different viewing angles. You can also turn the entire mirror face to a horizontal or vertical position - whatever works best for your application. Rubber pads on the straps protect the back of your factory mirror to prevent scratches when this mirror is installed for towing. Tools and other hardware aren't needed for installation, and the tight fit means there is no danger of losing these mirrors on the side of the road. You'll be ready to travel in minutes, and the increased field of vision will allow you to cruise the highways stress free.

Only Exception is I need longer mirrors looking to buy longer mirrors soon The mirrors worked great, never removed them from factory mirrors. Held in places no issues. Do need longer extensions for my towing application. Would prefer mirrors with longer extension. Im towing with 2008 gmc Acadia

Great, very pleased. Towing mirrors have improved greatly since my 1st pair in 1968. KS3891 has the most adjustable and tight fitting for least vibration.

Thanks for the follow-up. Yes, still using and appreciating the towing mirrors. Theyre easy to install, provide good visibility and provide a stable image when on the road. What more can you ask for?

So far, so good. The only complaint I might mention is the the straps should be permanently attached to the mirrors. They have a tendency to come off while you are putting the mirrors on. Other than that, they work well!!!

So on a Tacoma with a cargo trailer I found I only need a mirror extension on the passenger and a spot mirror added to the drivers side. I drove over 5k miles last summer and the mirror straps stayed intact and had no negative issues on the factory mirror so Im happy!

Honestly, I am not a fan. One fell off going down the highway and busted into a billion pieces.
