What options does your truck have? I can get the info, just need to know if you have the safety package, the forward facing task lamps, etc.

Power folding, puddle lamps, front task lights, and blind spot.

Still not understanding what HD mirrors do for you that the accessory version wont.

People have torn their trucks apart trying to add power fold only to find out the dash harness doesn't have the connector to swap their door harnesses

My truck already has power folding and blind spot mirrors, I'm just trying to swap to power folding tow mirrors.

Could you also get the build date for your truck too? Should be on the door jamb sticker that has the VIN on it.

Thanks.

So I went out on the lot. The HD mirrors have a different mount than the 1/2 ton tow mirrors due to the door design, so HD tow mirrors won't fit. As a matter of fact, they don't share any sheet metal besides the roof panel really.

You would need the 1/2 ton tow mirrors DQS full feature to make all your existing functions work and to fit your doors. You would need the following parts:

84753421 driver mirror

84753422 passenger mirror

84655846 passenger door harness

84655845 driver door harness

Nothing is on backorder, GM shows stock. Those mirrors will include the cameras for the surround view, its almost a guarantee that they won't be able to function however. All your other functions would be retained.

Okay thanks, that's exactly what I was wondering, sucks that the HD mirrors don't fit since they're so much more plentiful.

Yah I know for sure my truck doesn't have the correct modules to support 360, so I'm not expecting them to work.

I see that now on the build and price site. Price jumped $7K! Too funny. Funny sad not funny haha.
Adding the mirrors automatically added the following packages:
Technology - LTZ Convenience - LTZ Convenience II - Safety - Safety II. Removing any one of those removes the towing mirrors.
How stupid of GM!
The tow mirrors on my LT Trail Boss were a $345 option. No package add-ons necessary. The tech/camera package is cool. Very cool. But NOT even close to $7k cool! I just want to be able to tow my 20' boat safely.
I am on my 8th truck in the last 18 years so you can safely say I am a GM fanboy. When looking for my most recent truck (see my signature) I had just three requirements. Leather, tow mirrors, 6' 6" bed. I got all three. Would have been nice to be able to get cooled seats as the only leather available in the LT TB is black. Cooled seats are not an option on an LT so I had the windows tinted. It helps a lot. Power folding mirrors would also have been nice. Again, not an option on an LT. I digress. I am super happy with my truck!

If Chevy offered a LTZ Trail Boss, I would've been all over it with the towing mirrors.

I wish they made a LTZ “Diesel off road package” like they have for the LT and RST

Hopefully for 2021. TBH all 4X4 3.0 should come with 3.73.

I knew it was going to feel different, didn't realize it would be so drastic. Really helps at the top of the rev range, and actually gives meaningful engine braking. 3.23 engine braking is honestly only better then going down in neutral. Very underwhelming.

Can you get the parts #'s for a Sierra also? Has the tech pkg, 360 view, power fold, task lights, 02/20 build.

Well I will have more info in a few weeks. Found fully loaded driver and passenger side tow mirrors on ebay for $200 each. Passenger side is from a Silverado and Driver side is from a Sierra, both are from 1500 trucks too. After looking more into the HD wiring, their wiring has some BCM wiring that half ton truck do not have, this is specifically for the fully loaded mirrors.

pewterliftedz · August 3, 2020

Installed the passenger side (Part# 84709962) so far the mirror moves and power folds normally. This one came off a 2020 Silverado, so it fit fine, the driver side that I have coming is off a Sierra. I’ll update once I get the other side in.

Once I confirm both sides will mount and adjust I’ll start working on getting the lights to work. I’ll probably just buy the factory harnesses to make it easy

Well bad news just as I figured, GMC mirrors do not fit properly. I had my doubts, but figured I’d take the chance at $200, now I’ll just resell it later. Yes they do bolt up, but the body lines don’t match. I’ll be making some sort of gasket to fill in the spots where is doesn’t meet the body correctly. This will of course be temporary while I hunt for another Silverado mirror for the driver side.
Here’s a pic, I have a piece of foam in there for test fitting

Installed, it’s not perfect, but i made it work. Only function that I can tell that I lost is memory recall on the passenger mirror, driver side does function properly. Next will be buying the correct door harness to see if all the lights work

chris84 · August 12, 2020

Nice!

How much trouble is it to pull the door panels? I got a set of tow mirrors & the the guy I bought them from is getting new door harnesses & is going to give me a deal on his. Should be able to swap mine in a couple weeks
