** Click HERE for the Mirror Gear DIY Article for Full Size GM Trucks **  or (Download PDF)

** Click HERE for the Traverse/Acadia/Outlook Supplemental Instructions **


** 3 Options Are Now Available ***

Option 1: 

Buy strengthened brass gears + hi-torque motors in quantity of 1 set for 1 mirror or 2  sets for both mirrors ($49.99 / $89.99). Requires 24 hour epoxy of brass gear onto main shaft in your unit.  You will re-use your existing main shaft and epoxy on a new brass gear section.


Option 2:

Buy strengthened brass gears pre-mounted to a new machined steel main spiral shaft + hi-torque motor in quantity 1 set for 1 mirror or 2 sets for 2 mirrors ($64.99 / $99.99).  Does not require any epoxy cure time to install, its plug and play.


Option 3:

Buy a rebuilt complete motor drive unit with new hi-torque motor and brass gear pre-installed and tested ($229.99 minus $30 core return = $199.99).  Please note when buying the complete drive unit, you must choose passenger side or drivers side, and there is a $30 core refund so be sure to send back your old assembly in repairable condition.  Core returns are only applicable to complete drive units and when you are ready to return your core, please email for instructions.  Your CORE must be rebuildable.  We cannot accept units which have parts other than the motor/spur gear broken as cores as we would have no way to rebuild them.


Other Parts Available :

We also carry a limited number of used parts to service these mirrors in case you loose or break something.  We have some of everything, so just email if you need something.  We do now have some used mirror glass drive units for both sides - these are the little motorized units that actually adjust the angle of the mirror glass.


** Product Description ** is pleased to announce replacement strengthened BRASS spur gears and high torque INTERNALLY GROUNDED motors (OEM MOTOR WONT WORK WITH METAL) for the power folding mirrors on 2007-2014 GM trucks including Acadia, Traverse, Enclave, Escalade, Silverado, Avalanche, Tahoe, Suburban, Sierra, Yukon, and Denali.  Also fits ALL 2007-Present GMC pick-up trucks. As many have discovered, the folding mirror assembly on these trucks suffers from a thin, weak, plastic spur gear mounted to the main drive shaft.  The plastic spur gear cracks at the slightest impact or just wears out over time causing an inoperable folding mirror.  The GM motors also get weak and die quickly. Unfortunately, GM will only sell you a complete folding mirror assembly, which will cost you from $700-$1,200 ea after labor and paint, depending on the year/make/model.  And that $ would be wasted on another mirror assembly with another weak, plastic spur gear and weak electric motor that will also soon fail.  Don't waste time or hard earned money on more GM parts that will also soon fail! has addressed this issue by designing a strengthened spur gear made from solid gear BRASS with a thicker cross section to eliminate the stress concentrations which cause fatigue cracking in the GM plastic gear. We have also designed a replacement high torque electric motor to accompany this new metal gear. Our new electric motor is required when switching out to the metal gear, as the ground circuit in the OEM motor does not allow for a metal gear to be installed. You can buy the gear/motor combo for one of both sides, and with the spur gear pre-attached to a new main shaft, or loose. Loose gear orders require installation of the spur gear onto the main shaft using 24 hour epoxy - please refer to the DIY article link above.  We have thoroughly tested our redesigned spur gear and high torque motor using a new, OEM mirror assembly and computerized test equipment.  Our test samples barely showed any wear whatsoever, and the testing did include random wacks against the mirror, jamming the mirror operation as it was folding, and manually stressing the mechanism all in an attempt the break the gear.  Each sample was tested more than 5,000 open/close cycles and was still going strong at that point !  

This product carries a LIFETIME WARRANTY!  Provided you don't burn the vehicle, or otherwise smash the mirror into something, you can send back the motor drive unit to us and we'll replace the gear assembly and get it working again free of charge.  You would only be responsible for shipping under this warranty.

  1. Money savings DIY fix 5 Star Review

    Posted by on 8th Apr 2021

    After buying parts I kind of set away and kept putting off the repair thinking it was gonna be in depth repair. After doing the drivers mirror in maybe 2 hours and realizing it wasn't that bad I did passenger mirror in like 45 minutes. I will suggest to spend the extra $10 and buy the gear already mounted to spindle I did premount and the single gear I had to glue. Easy to glue it but their is a 24 hour waiting time before reinstalling the gear assembly back into the gear box. With preinstalled it's disassemble swap and reassemble. Can't say how happy that I did this and both mirrors work great and saved me a fortune and needless to say buying the new mirrors from dealer is expensive and will break just like first ones

  2. Folding Mirror Motor 5 Star Review

    Posted by on 7th Apr 2021

    I replaced my folding mirror motor with a new gruven motor and it worked great, you can tell the motor is strengthened because my passenger mirror folds in a little faster than my drivers side and my drivers side mirror is new factory mirror

  4. excellent choice 5 Star Review

    Posted by on 28th Mar 2021

    My mirrors stopped folding and became bouncy on my 09 Silverado. I was referred here by a forum member. At first i was ify. But ordered anyway. Maaannnn am i glad the worm gear is soild. And altho the gm motor has a brass gear (atleast mine did) these new ones definitely live up to the term high torque. And the instructions omg could not of been any easier. Loved the extra tips. Kinda wish i was told i had to go online to get them but none the less great write up and great gear/motors.

  5. Very satisfied customer 5 Star Review

    Posted by on 27th Mar 2021

    2007 GMC Took me awhile to get to swopping new motor with the old ( below freezing for extended periods ). I followed the installation video and had no problems - the video was easy to follow and poined out any possible problems you might run across. Took me about an hour and a half cause I'm very cautious. New motor is way better than the old one - in every way.

  6. What GM should have installed at yhe factory 5 Star Review

    Posted by on 23rd Mar 2021

    After USPS finally delivered the motor assembly, the install was easy. Following instructions from the website made the removal and install a piece of cake. The mirror assembly works fantastic and the way it should have from day one. If and when my driver's side mirror motor goes out, I will be purchasing that one too.
    This is the best thing you can do to fix the plastic motor gears that GM installed.

  10. GM power mirror motor/gears - Save over $200 for each mirror 5 Star Review

    Posted by on 2nd Mar 2021

    I ordered the pre-made gears, as I did not want to take the time to epoxy the gears on my old shaft. Took me 1.5 hour for both mirrors; to disassemble, replace the gears/motor and reassemble. The motors sound louder but when it only takes 1 - 1.5 seconds to get the mirror in/out you really can’t complain. I watched the video first and followed there steps. Video is easy to follow and makes the process of doing it yourself painless. Hardest part was to separate the housing from the gears. I worked with two flat head screwdrivers and got them apart quickly. Both my plastic gears were cracked/broken. Get some white lithium grease before you start. Use the tub of grease and not the spray on. Apply liberally on the new gear set and the turning gear. Does not state that in the video but I ensured everything was covered and it helped lessen any additional noise from the gears when turning. Overall, I am very satisfied with the easy of replacement and how well it works now.
