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


** 3 Options Are Now Available ***

Option 1: Sorry this option is currently not available.

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 paul@gruvenparts.com 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 paul@gruvenparts.com 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 **

GruvenParts.com 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 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!  

GruvenParts.com 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. Mirror motor and gear 5 Star Review

    Posted by on 12th Dec 2019

    Just finished installing passenger side motor and gear on my 2007 Yukon Denali.
    Parts worked great and thanks again to Paul for his quick response to my email about a broken collet and his solution . Thanks again!!

  2. Dont get any better 5 Star Review

  3. Parts worked well 5 Star Review

    Posted by on 4th Dec 2019

    Parts worked great Just had problem with spring retainer getting it in the right spot .

  4. Chevy power fold mirrors 5 Star Review

    Posted by on 27th Nov 2019

    Pre assembled gear and motor worked great . Mirror folds much faster than stock Chevy mirror. Install video is great but still leaves room for error. I negelected to note that the mirror mounting to the frame is keyed and had it misaligned. Managed to get it right on the second try. Compressing that spring and locking it is a real challenge. Will probably need to rebuild the other mirror soon. Very satisfied and saved a bundle.

  5. Great parts 5 Star Review

    Posted by on 27th Nov 2019

    Fast service and great parts. Online directions and video made this a very easy project. First mirror took a little over an hour the second about 30 to 40 minutes. Removing the mirror glass was the hardest part. Lots of patience. Perfect solution for an imperfect part. Thanks for everything.

  6. Great product! 5 Star Review

    Posted by on 26th Nov 2019

    I bought 2 of these gear sets. Replaced them and now the mirrors work better than when they were new. Highly recommend!

  7. great improvement 5 Star Review

    Posted by on 22nd Nov 2019

    Was a little worried that I couldn't find a phone number to call a order in or reviews on other web sites but they are legit every aspect of the replacement parts are 100% to described specs. Major improvement over the oem pieces. Shipped same day Friday arrived Tuesday. Good online video. If need be will buy from them again!

  8. Good solution for a failed mirror retract mechanism 5 Star Review

    Posted by on 15th Nov 2019

    This product provides a less expensive repair solution versus the expensive replacement of the entire mirror (manufacturer option).

    Shipping and handling time was disappointing.

    -- Response --

    Sorry for the slower than normal shipping time, if this was ordered on Thanksgiving or that week things were very hectic but we tried our best to get them out. Not sure who left this review but as always you can contact us via email paul@gruvenparts.com and we reply very quickly - go ahead and try it and confirm that. But I appreciate the honest feedback and we are working to speed up the shipping time.

  9. AWESOME Instructions - very detailed ! 5 Star Review

    Posted by on 10th Nov 2019

    It took some time to do the first one; had to redo after re-installation - had some play in mirror (inadvertently offset the inner spline gear from collar) . Second one went very smoothly and much quicker.

    Found a easy trick to press off the lock washer - used my drill press, simply centered the square top of 1" socket in the chuck triple splines and with gentle, controlled pressure, then used channel lock plyers to turn spring/washer and ... voila !!!

    -- response --

    Thanks Colin, and yes any sort of press works great. I use the small table arbor press from harbor freight and its perfect (and cheap). You can also squeeze oranges when you are done :) Seriously - be safe with this step, wear eye protection, and if you are at all unsure about the stability of the spring and retainer, go ahead and run some wire around the spring to contain it in the event and not let if fly out if something were to slip off. I know alot of people are using the 1" PVC pipe length to just lean on it and compress/turn in the field and that s fine but take precautions as its a heavy spring. Eye protection is essential and wire tire the spring if unsure.


  10. chevy truck mirror 4 Star Review

    Posted by on 6th Nov 2019

    I purchased the motor and gear for my truck mirror. A slight problem with the gear was addressed by the company.
    Without the excellent repair direction's I'm not sure I could have completed the repair. With the new parts the mirror works better and faster than the original.
