I've always liked having power folding mirrors, but I accepted that the positives of the manual-folding towing mirrors outweighed the OEM small power-folding mirrors. With all the towing I do, towing mirrors are simply a necessity. Another annoyance was the fact that the mirrors did not work with the memory seat function in my truck. I know, first world issues. When a memory button was pushed, one or both mirrors would sweep up and into a corner and would have to be readjusted. I was also concerned that this could eventually cause gears to get stripped.
A little over a year ago, Boost came out with power folding towing mirrors. I tried to resist. And I was successful for a time. But the evil bastards at Boost ran a Black Friday sale last November, and my resistance was broken.
So I ordered black towing mirrors, and got the following options - sequential turn signal, clear (not smoked) strip, no running light, hi-output backup spotlights, heated upper AND lower glass. And for simplicity I ordered the fuse tap for the backup lights from them. Total out the door with the discount was $886.82. They are custom built to order. Order was placed on 11/29/25, shipped on 12/8 (from IL) and arrived in Michigan on 12/9. Super heavy-duty box, no damage, and HUGE. So don't bother hoping to hide it from a spouse.
Unboxing - they were well-packaged and in perfect condition. Protective film had been applied to the LED strips, a nice touch. They seem a little fatter than the incumbent Trail Ridge mirrors.
Comparison
Having swapped out mirrors multiple times (my 3 kids learned to drive on this, so in addition to the initial install, I had to replace a few damaged ones over the years), the install went pretty quick.
Passenger side
Driver side - the wires are the leads for the backup spotlights.
The wires merge in the driver footwell, ground on the brake pedal bolt (you can see the eyelet with the blue collar, just above the brake pedal), and a single wire is run through the firewall to the load center.
I didn't take closer pics, but the mirrors plug into the power window switches on the arm rests on each door. There are two plugs for each mirror - this is your confirmation that they will work with the memory function. The wires had the Christmas tree fasteners in the correct location to easily snap into the existing holes in the door. And there was plenty of slack in the wire to make it easy to reinstall the window switches. Three nuts hold in each mirror - as usual, 10mm nuts.
Some finished installation pics:
Video of sequential lights - I'll post another at night time.
Good/bad/observations after a few hundred miles of driving - I have not yet wired up the backup lights, having trouble finding a good place to punch through the firewall. I'll update on them when it gets warmer.
I'll start with the bad - nothing major, or even minor - I'd call them nits to pick
1) I wish the convex mirror had more travel. I see too much of the truck, and that's as far as they go.
2) The red signal LEDs in the upper glass are BRIGHT. They're also omnidirectional, so the brightness is a little annoying at night. The Trail Ridge signal mirrors were more unidirectional, so you could they were on, but they didn't shine in your face.
3) There's a little vibration of the upper glass at highway speed. Nothing that makes images hard to see, just an annoyance. They're not rock-steady, but I'm also pretty sure I've never seen ANY rock-steady towing mirrors.
Good:
1) POWER FOLDING TOW MIRRORS!!!!! THEY F***ING ROCK!
2) Because I can fold them in now, I'll drive around with them permanently extended, which yields better visibility. My rear windows are 5% tinted, so the rearview mirror is basically worthless. Any additional view behind is a good thing.
3) Heated upper and lower mirrors.
4) Mirror memory function. I'm 6' 2", and my wife is 5' 2". Although she doesn't drive the Suburban often, she can adjust the upper mirrors once, and they'll then be programmed into memory.
5) The sequential signal is cool. And they syncrhonize perfectly with the sequential signals of my Alpharex headlights. So it kinda looks really cool.
6) Even though I haven't wired them up yet, I was a little worried that the backup spotlights might be blinding. But you can see the little cavity where they are has a small "wall" that blocks them from being in the direct line of sight of the driver.
7) Their installation video on their website makes it stupid-easy, even for first-timers.
Overall, I'm pleased. The power fold function is awesome.
