** Product Description **

GruvenParts.com is pleased to announce replacement strengthened BRASS spur gears and high torque motors 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. Just go ahead and buy 2! 5 Star Review

    Posted by on 4th Dec 2018

    I only bought one, as I wanted to make sure I could do it. Used a socket and the palm of my hand for the spring retainer, instead of my hydraulic press or drill press. 1 hour start to finish. I bet other side gets done in 30 min. And I would say get both sides, because it’s not if but when it will fail, and the new motor swings mirror faster than the oem one. Might drive the ocd guys nuts...

  2. Replaced Folding Mirror Motor and Gear 5 Star Review

    Posted by on 31st Oct 2018

    I purchased the pre-attached gear and motor. The instructions that I downloaded from the website were very good. It took a bit of time to accomplish but is doable for anyone with some mechanical aptitude. Removing the spring and re-installing the spring is most challenging part of this repair. A vise and a large socket helps in this regard. Once the repair was completed the mirror worked fine.

    -- response --

    Thanks Don. One thing we have found is for "field" repairs where perhaps a vice or arbor press is not available, some have used 1" PVC pipe to lean on the spring retainer and compress the spring while turning it 1/6 turn. For anyone who does this, please wire tie the spring coils BEFORE using this field method and make sure to wear eye protection. We dont want the heavy spring to go flying if you slip off the retainer when compressing by hand. The PVC pipe seems to grip the retainer better than a metallic socket or spacer.

  3. Brought my 07 suburban power mirrors back to life!! 5 Star Review

    Posted by on 9th Oct 2018

    I purchased the pre-mounted gear & motor and they worked like a champ.

    The PDF instructions were easy to follow, however I questioned grinding off the tabs, but did it anyway since I did not want to have any problems where I would have to dissemble the mirrors again. In all after a few hours doing both mirrors it was well worth the money and time to install this quality product. I hope they last a very long time.

  4. Easiest Installation EVER 5 Star Review

    Posted by on 8th Oct 2018

    I'm a female that was able to completely do this on my own. I had several doubts but with the instructions everything worked out great. Parts are worth purchasing when you compare it to GMC original plastic piece!

  5. Great Product 5 Star Review

    Posted by on 1st Oct 2018

    After I read the installation instructions CAREFULLY the installation went off without a hitch. The hardest part was removing and reinstalling the spring retainer which wasn't that difficult since I had the correct tools to work with. Everything else was a piece of cake. I chose Option 2 and the materials were of very high quality and the workmanship was perfect. If the other mirror gear goes out I'll definitely order another one.

  6. Plastic gets you to the GM WARRANTY 5 Star Review

    Posted by on 24th Sep 2018

    Thanks to Gruven for making the REAL parts to go the lifetime

  7. Perfect drop-in parts 5 Star Review

    Posted by on 11th Sep 2018

    I bought the pre-mounted gear & motor. The design is perfect, it just dropped right in without any issues! When I got the assembly taken apart, I discovered that the old plastic gear was literally broken in half, there is no chance of that recurring with this beefy brass replacement.

    The PDF instructions were also excellent, I had no problems knocking out this job.

    My mirror doesn't shake anymore, *AND* .... it will actually fold in/out when I press the button!

  8. great quality 5 Star Review

    Posted by on 2nd Sep 2018

    Very well made

    Ordering the seat adjusters next

  9. This is what GM should have installed in the first place 5 Star Review

    Posted by on 1st Sep 2018

    Great product. Instructions were very clear and installation went very smoothly. Now I have Turbo mirrors!

  10. It's Easy and They Work 5 Star Review

    Posted by on 1st Sep 2018

    Both of the motor-driven folding mirrors on my 2010 Suburban had stopped working. I read reviews online and decided Gruevenparts replacement gears and motors seemed to be the best option. I viewed the video on how to disassemble the mirror and got to work. Everything went just as the video portrayed. When I got down to it, I found that the plastic gears on each mirror had cracked. Replaced them with the new brass gears, which required no modification to fit, and reassembled the mirrors in reverse order. Both are working like new.
