** 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. Works in RAM 1500 5 Star Review

    Posted by on 19th Mar 2019

    The plastic gear in my 2013 RAM 1500 with the heated power folding mirrors broke. A quick search online and I found these. Dropped right in and works great. Thanks! Saved me about 800$ for a mirror assembly.

    Thanks Tommy for that info. I didnt realize Ram also used the same drive unit as GM did !


  2. Great products from people who care. 5 Star Review

    Posted by on 19th Mar 2019

    Paul Gruven is a brilliant caring craftsman.
    It was a pleasure doing business with Paul.
    I was treated more than fair.

  3. Great Product, better option than buying a new power folding mirror! 5 Star Review

    Posted by on 16th Mar 2019

    I sides wiped a mailbox, and eventually my passenger mirror stopped folding. I did a lot of research. The dealer wanted $650 for a replacement 2011 Tahoe power folding mirror. I found Gruven, asked a few questions and eventually bought a replacement motor. The process to replace the motor is straight forward, just follow the instructions. My only problem was the heater wires, the contacts were rusted onto the mirror prongs, I had to keep working them with pliers, they finally came off. It definitely moves faster than the original drivers side mirror. I have had no issues after putting everything back together.

    Awesome product!

    -- Response from GruvenParts

    Thanks DeWayne for the review. Regrading those heater wires, I know what you mean. If they are really rusted onto back of mirror, sometimes I clip them and resolder them. We just want to be very careful not to break the tangs off the back of the mirror. Normally and gentle up/down while pulling motion gets them to come off but if rusted solid, I would suggest clipping the wires then just resoldering. It doesnt matter the orientation as its just a DC electric heater in there so it can power in either direction.


  4. Built to last! 5 Star Review

    Much stronger and more durable...the way it should have been from factory!

  5. Power mirror motor replacement 4 Star Review

    Posted by on 9th Mar 2019

    The rebuilt motor was exactly what I needed, works great and with the help of YouTube videos removing and installing was a breeze. The mirror works perfectly. The only reason for the four star rating was the 8 days to receive the motor and I thought a little expensive for a rebuilt.

  6. Excellent Fix for OEM Junk! 5 Star Review

    Posted by on 3rd Mar 2019

    Great bunch of people to buy from! Install, both sides, hour and a half. Hint: Clamped a 6" C- clamp vertical in vise, used appropriate sockets on top and bottom to compress and hold spring.

    -- Response --

    Thanks Tim. Also, you can use a short length of 1" PVC and body weight to press down on the spring retainer. Wear eye protection, and go ahead and wire tie the spring to the unit incase you slip off. This works well for "field repairs". We use a vice with tooling to compress but a length of PVC also will work fine out in the field to quickly compress and rotate and release the spring retainer.


  7. Excellent product 5 Star Review

    Posted by on 3rd Mar 2019

    Drivers side mirror wouldn't fold and flopped around on my 2007 gmc yukon. Ordered these fixed the drivers side. It was really easy and instructions were perfect. Did the passenger side also because the drivers side worked so smooth and fast. Excellent product and company. Highly recommend!!

  8. An absolute fix! 5 Star Review

    Posted by on 27th Feb 2019

    Had a learning curve on the first side (make sure the new motor is facing the right way for the electric connection), so I basically did that side twice. It took me about an hour and a half to do the second side. Once done, they work better than new.

    -- Response--

    Thanks Mark. We just revised the DIY article now posted in the product description, hopefully this clears up any confusion. Please let us know if there are any other suggestions to improve the DIY article.


  9. Excellent product! Problem solver! 5 Star Review

    Posted by on 21st Feb 2019

    Both of my power fold mirrors on my 2011 Silverado had broken gears in them. Mirrors floppy and not folding. Ordered these after finding them through a forum. Install is very easy with only a couple basic hand tools. Totally worth it and both of my mirrors work perfectly again.

  10. Great Product 5 Star Review

    Posted by on 21st Feb 2019

    these work great, instructions are perfect and customer service is excellent!
