** 2 Options Are 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 steel gears machined integral to the 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 + steel integral gear already 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.

***** 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.  

 

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 STEEL gears and high torque INTERNALLY GROUNDED motors (OEM MOTOR WONT WORK WITH METAL) for the power folding mirrors on most 2007-Present 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!  

GruvenParts.com has addressed this issue by designing a strengthened integral spiral spur/worm gear shaft made from high strength steel to eliminate the 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 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 integral 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.

 

** Application ** 

Gears and Motors Fit Both Passenger and Drivers Side Power Folding Mirrors.  

All 2007-Present GM Pick Up Trucks Including all Silverado and Sierra with Non-Towing Power Fold Mirrors -- please note the 2014+ pick up trucks used different plastics on the frame, so disassembly of the mirror frame doesnt match the previous gen DIY.  The lower half of the drive unit with all the gears inside IS the same as the previous generation.

All 2007-2014 GM SUV's With Power Folding Non-Tow Mirrors Including Acadia, Traverse, Enclave, Escalade, Tahoe, Suburban, Yukon, and Denali. 

This includes (but not limited to) the following mirror assembly part numbers :

25-83-12-36 (25831236), 25-77-98-49 (25779849)

This list of part numbers will continually grow as we build the interchange list.  This is in no way complete, as most GM trucks made from 2007-2014 with power folding mirrors will use this gear.  If your power folding mirror looks like the mirror shown in the DIY, this gear will fit your vehicle.

 

... We also have many more products for GM, including the towing mirror gears, 2015-Present SUV non-towing mirror gears, door lock motors, door handle inserts !  Check out the GM section of our website!

  1. What GM should have made! 5 Star Review

    Posted by on 1st Sep 2025

    Awesome! My mirrors (2019 GMC AT4) now work the way they were supposed to. One brand new mirror from GM would have been over $500 since mine have lights , cameras and sensors. This was a fraction of the cost for OEM replacements. I can't believe how cheap the original one's were made, these are much better and having the peace of mind knowing they will last is priceless.


  2. PRODUCT/TRANSACTION REVIEW 5 Star Review

    Posted by on 28th Aug 2025

    FIRST TIME TO ORDER FROM GRUVEN PARTS. ORDERED PART TO REPLACE MY PASSENGER SIDE TAHOE FOLDING MIRROR MOTOR ASSEMBLY. SHIPMENT OF PART WAS VERY PROMPT. INSTALLATION WENT SMOOTHLY. I AM IMPRESSED WITH PRODUCT AND SHIPMENT WHICH WAS VERY PROMPT. IF NEED BE, I WILL ORDER AGAIN FROM THESE FOLKS!


  3. PRODUCT/ORDER REVIEW 5 Star Review

    Posted by on 28th Aug 2025

    PART ORDERED WAS EXACTLY WHAT WAS NEEDED TO CORRECT MY PROBLEM WITH MY FOLDING MIRROR MOTOR PROBLEM. SHIPMENT WAS VERY PROMPT AND PART WAS VERY EASY TO INSTALL. IN FACT, INSTALLATION WAS BETTER THAN UTUBE VIDEO THAT CAUSED ME TO ORDER. I WOULD ORDER AGAIN FROM GRUVEN SHOULD MY DRIVER SIDE MIRROR MOTOR STOPPED WORKING. I CONSIDER THIS A VERY GOOD TRANSACTDION.


  4. worth the money 5 Star Review

    Posted by on 27th Aug 2025

    I ended up going with the GruvenParts rebuilt motor assembly. I didn’t have the tool necessary to grind the “collett” down as shown in the video. The motor was a drop in replacement and works like a charm through all steps of reassembly. I’m glad I found GruvenParts online. The factory mirror assembly for my vehicle was going to be over $500 for a new one! The rebuilt motor from GruvenParts was less than half of that and I didn’t have to take the inner door panel out to replace it!


  5. Excellent repair parts 5 Star Review

    Posted by on 26th Aug 2025

    This repair kit for my 2008 Escalade is absolutely great! Better than OEM by far. Great value and an excellent tutorial video to complete the repair. This saved a lot of money and will probably out live the original.Thanks.

    Next is the door lock actuator that's broken.


  6. Easier than I thought it would be 5 Star Review

    Posted by on 23rd Jul 2025

    It was alot easier than I had anticipated. Everthing worked well and now my mirrors are fixed. Don"t let it scare you, take your time and follow the instuctions and the installation will go great.


  7. Gruven saves the day repairing my 2015 GMC Denali broken folding mirror motor 5 Star Review

    Posted by on 18th Jul 2025

    My 2015 GMC Denali driver side mirror stopped working/folding in-out. Did some research and found this company who repairs the broken plastic gear. After a few emails, paid the fee on their website, reviewed the instructions to take out the motor and ship it to them. Took about 10 days, more travel time than the one day they took to repair it. Way cheaper than a new one for sure.
    Works like a charm and highly recommend them as they have other parts for different vehicles that they also ‘upgrade & repair’ as the manufacturer use cheaper plastic parts that fail over time. Check them out,


  8. Better than OEM 5 Star Review

    Posted by on 16th Jun 2025

    Installation would have been a real puzzle were it not for the excellent step by step video tutorial.
    when all done and the mirror rotated smoothly and quietly, I knew I'd made the right decision to go with Gruven Parts


  9. perfect fit and quality 5 Star Review

    Posted by on 14th May 2025

    Communication and shipping was quick, product is a great upgrade / replacement for the cheaper factory version

    Thank you!


  10. Folding mirror motor/gear assembly for GM 5 Star Review

    Posted by on 8th Mar 2025

    Folding mirror replacement motor & gear assembly for my 2019 GMC 1500 Sierra Denali is a very nice upgrade over factory installed plastic. Emailed Paul a few times with questions and he responded quickly with good advice. Would recommend this upgrade to anyone with a similar situation. Replacement mirrors from GM are over $1,000 each, and they don't retail replacement internal parts.
