** 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 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. Great Parts, well made, great customer service. 5 Star Review

    Posted by on 19th Mar 2020

    Had a bit of trouble with first side, made a call to Gruven on a Friday about 5pm and left a message. They called me back and got me straightened out about 10 minutes later! Second side went much easier. I could have done a 3rd one in about 25 minutes, now that I'm an "expert"

  2. Excellent product and customer service! 5 Star Review

    Posted by on 2nd Mar 2020

    Glad I found gruvenparts.com after my power folding drivers side mirror stopped working on my 2011 Silverado 2500HD. Ordered two motors and gears since I figured it was just a matter of time before the passenger side mirror would stop working. This was confirmed after disassembly. The passenger side mirror gear was cracked. Ordered new parts on Friday and received them on the following Monday! Quality of the new parts and instructions were excellent. The power folding mirrors worked flawlessly after the new parts were installed. Thanks gruvenparts.com for an excellent product and for offering an alternative to spending hundreds of dollars at the dealership.

  3. I saved $650...you can too! 5 Star Review

    I was quoted $700 to fix the folding mirror by the stealership. I bought this and followed the video instead. I enjoyed a steak dinner with the savings.

    Thanks, wish more people knew, Ive been saying this forever :)

  4. Great fix and documentation 5 Star Review

    Posted by on 4th Feb 2020

    After the mirror would no longer work (put up with it for a while) I found Gruven Parts and read their docs about how to take apart and install the gear. I ordered the part and got it in 4 days. Following the docs and presto all fixed. I am sure that the other side will fail in time and I will get that one fixed to. I decided not to grind off the tabs on the bottom and see if it makes any difference. So far it still moves faster that the original one. Using a socket and vice the spring can be compressed and then use a large pair of pliers to slowly rotate the keeper ring to match up with the bumps then SLOWLY release the spring to take apart. Place a rag over the entire unit when releasing just in case. Put all new grease in while you have it apart. Nice fix and I am very happy with the results.

  5. Great replacement parts 5 Star Review

    Posted by on 27th Jan 2020

    Parts are very high quality and fit well. The video of the instructions is detailed and made replacement a breeze. These also operate at least twice as fast as the OEM motors. Great product.

  6. Works Great! 5 Star Review

    Posted by on 21st Jan 2020

    I installed the kit, 2 gears & 2 motors, the same afternoon I received them. I had watched the installation video before ordering them and double checked a couple of things during the install. They both worked great. The passenger side was broke when we bought our suburban & I didn't normally use them because of that. I accidentally hit the fold button the other day & the drivers mirror broke in a bad angle. Time for repairs. Now I use them regularly due to the size of our vehicle taking up most of the sparing space. Thanks for making a repair available & affordable. Wish I'd done it earlier.

  7. Great product 5 Star Review

    Posted by on 8th Jan 2020

    Excellent gear set. Ordered sets for both sides. Did the drivers side as the passenger side still works with the old gears. Followed the instructions on the web site. A little daunting to do but everything came apart the way the instructions said. The mirror now works better than the original passenger side one. I will be changing that one in the spring. I used three or four rubber bands to keep the mirror in place instead of tape and that worked great.

  8. Great product, better instructions 5 Star Review

    Posted by on 6th Jan 2020

    Purchased the gear and motor combo. The gear is clearly superior to the OEM plastic component, as expected. I am most impressed with the detailed YouTube video showing how to install it. I never would have made it through the process without it.

  9. ‘09 Silverado 5 Star Review

    Posted by on 5th Jan 2020

    I bought the full kit of both gears/motors. They fit perfectly and perform well. I feel confident that they will last the life of the truck.
