Product Description



*** You Cannot Just Install a Metal Gear Without Also Changing The Motor To The GruvenParts INTERNALLY GROUNDED MOTOR !  You Will Short Out the Body Control Module.  All Of Our Kits Come With New Motors Which Are Internally Grounded and Work With Metal Gears - So Don't Just Replace the Gear, You Must Replace Both Gear AND Motor When Going to Metal !!! ***



 ** Click HERE for the NEW GruvenParts Installation Video **

** 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 **


** 2 Options Are Now Available ***

Note that if you chose Option 2, you will either need to send in your unit for repair directly, or wait approximately 2 months for us to get a unit to repair.  These are becoming hard to find and people arent returning their cores as often anymore for some reason.  We can usually repair sent in units same day to minimize down time as you cant install the mirror without the drive unit in place.

Option 1: 

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).  

Option 2:

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.

***** PLEASE NOTE WHEN ORDERING THE COMPLETE DRIVE UNIT - If you are in a hurry for this, its best to check with us to see if we have any cores.  It could be 4-6 weeks to receive this, based on how many units we have in the shop.  People do not send back their cores very quickly, so we are usually waiting.  You can send in your own unit to be worked as well, and we will apply the $30 core when you send in and try to work it same day or very quick.  We are currently on a 2 Month Back Order Unless You Can Send In Your Unit to be Rebuilt


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 chose to buy the gear/motor combo for one or both sides with the spur gear pre-attached to a new main shaft or you can buy complete drive units which are rebuilt and already have the new metal gears and hi torque motor installed in them.  

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. Great upgrade! 5 Star Review

    Posted by on 10th Nov 2021

    Great upgrade. Mirrors work great now on my Escalade It’s a must have!!

  2. Works perfectly 5 Star Review

    Posted by on 8th Nov 2021

    Works perfectly for a 2014 Chevy Silvardo 1500. Only minor differences between instructions and actual installation is that on the 2014 model, the motor is in a plastic housing. You have to remove the old motor from the housing, then remove the new motor from the metal housing and use the original plastic housing. Also, the small electric motor is pointing the opposite direction of the original. Have to pop it off, turn it 180 degrees and put it back on. The original also has a circuit board on this same electric motor. Pull off the circuit board and install it on the new electric motor. Very easy; plug & play and takes just a few seconds. The rest of the install is just like the instructions.

    One do I return my old motor/core for the refund? I've emailed Paul a couple of times but so far haven't heard back.

  3. Better than factory 5 Star Review

    Posted by on 5th Nov 2021

    I ordered the gear and motor because price was that much different and my motors still worked. The first mirror took awhile because it was the first mirror was a little tricky but got it and everything went well. Watch the video while doing the work and it will help you with removing and installing everything. I even watched the video while doing the new gear and what needed to be done. Got the parts fast but took me a couple weeks to get it done.

  4. Great repair parts 5 Star Review

    Posted by on 3rd Nov 2021

    We bought my daught an Avalanche for her first vehicle. One mirror was not retracting. We replaced both at the same time. This was the first project we tackled to keep her new (to her) SUV in good condition. She has to help with anything we do on it. She is independant and wants to be able do it herself when she's off to college in a few years. The mirrors work great now. A bit noisier (greased), but not bad.

  5. Mirror Repaired with New Motor 5 Star Review

    Posted by on 2nd Nov 2021

    Received the new motor assembly, watched the installation video and changed out the broken motor with no issues. The new motor worked great. Very good product.

    Thanks, Marcus

  6. Never compromise... 5 Star Review

    Posted by on 1st Nov 2021

    I've had to deal with 2 different mirror motor gears being stripped on my 2011 Sierra. The first time I replaced the mirror, then it broke again. This Gruven parts assembly made my folding mirror look, feel, and sound like a sexy tank. It wasn't too bad doing the replacement. I just followed along with their excellent youtube instruction video. I did the required grinding on the ring using my Dremel with grinding stone attachment. I managed the replacement in a couple of hours with a non-gearhead stocked garage. I'm buying another set to do my other mirror because it moves like a one legged mule in comparison to the Gruven upgraded mirror.

  7. power folding mirror gears and motors 5 Star Review

    Posted by on 31st Oct 2021

    Parts work as I was told, installed and working

  8. Perfect. 5 Star Review

    Posted by on 28th Oct 2021

    Perfect rebuild. Mailed in a core on a Saturday, had the product back and installed by the next Saturday.

  9. major improvement over GM engineers 5 Star Review

    Posted by on 28th Oct 2021

    So far the brass replacement gears and modified electric motors for the retractable mirrors on my 2009 Avalanche are working very well. At least they should not crack like original parts did.

  10. side view mirror motors and gears 4 Star Review

    Posted by on 20th Oct 2021

    I installed the motors and gears today. Pretty simple after watching the video. Only gave them 4 stars because they are a little noisier than the original nylon gears. You tell thought that they much better than the OEM parts

    -- response --

    Thanks for the review. Yes a bit more noisy as its metal on metal rather than plastic sliding on metal. You can mitigate the noise some with white lithium grease. It should break in over time as well. Thanks for review.
