** 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. Replacement brass gear & motor 5 Star Review

    Posted by on 12th Aug 2019

    This is an outstanding replacement part which exceeds the OEM plastic gear. The brass gear already mounted on the worm gear is the way to go. Cost of the part is reasonable & shipping was fast.

  2. Better than OEM 5 Star Review

    Posted by on 6th Aug 2019

    I purchased the Option 3 assembled motor unit for GM mirrors which fold in and out. As the Gruven website states, they provide a brass gear, unlike the plastic gear which GM installs in the motorized mirrors.
    Just installed it today (actually had it installed), and I’ve never seen the mirror fold in and out in such a powerful manner. The part carries a lifetime guarantee.
    Well worth the price, and a phone call to Gruven puts you in touch with a real human who answers the phone and is very helpful. No menu choices to play thru.

    -- Response --

    Thanks John! Yeah no menu choices lol its just my cell phone. I hate menu choices as well, so frustrating.

    If i dont answer please do leave message and I will always call back.

    Take care and let us know if you need anything else.


  3. mirror gears and motor 5 Star Review

    Posted by on 29th Jul 2019

    easy to put on and works great

  4. brass gear did the trick 5 Star Review

    Posted by on 24th Jul 2019

    The brass gear and motor fixed my mirror. The instructions were well written and easy to follow and made the job much easier. The shipping was quick.
    Thanks Gruvenparts for a great part and instructions. Saves us a lot of $.

  5. Unbelievable Service!! 5 Star Review

    Posted by on 20th Jul 2019

    I bought the gear and motor. I took everything apart and found that I couldn't take off the motor cover as I don't have a vise. After a few hand jabs with a screwdriver, I contacted GruvenParts. Paul responded and just offered to put it together for me!! I sent the parts to him, and he had them installed and on their way back to me in minutes after he got them!! Unheard of service !!! I'm actually looking forward to the other side breaking downs!! But, next time I'll get the whole thing assembled....

  6. precision product designed to solve a defective OEM design 5 Star Review

    Posted by on 16th Jul 2019

    The machined products are extremely well made and fit perfectly. The online instructions are detailed and well prepared.

    Most importantly, Paul at GruvenParts was very quick to respond to my installation question since the 2010 Buick Enclave mirror came apart in a slightly different manner then the Traverse.

  7. Everything I Expected 5 Star Review

    Posted by on 15th Jul 2019

    Solid product. Direct replacement for the cheap plastic gear that GM in their infinite wisdom thought was a good idea. Purchased the pre-assembled motor and gears to save time, and as insurance if the old motors were bad also. Money well spent.

    Thank you Gruven for offering such a quality product

  8. Gears worked perfectly 5 Star Review

    Posted by on 12th Jul 2019

    The first one took an hour, the second one about 20 minutes.

  9. Worked perfectly! 5 Star Review

    Posted by on 10th Jul 2019

    My folding mirrors have never worked. Bought the truck used. Dealer disconnected harness to "hide" the issue. Found your product and had the confidence, after reading the instructions, that I could do the repair. First mirror took a while. Second mirror took less than 30 minutes. Read ALL of the instructions before you start. Follow the instructions!

  10. great product 5 Star Review

    Posted by on 10th Jul 2019

    Install takes time. Mainly the spring as I didnt have a vice so I used a 1in piece of PVC and body weight. I bought 2 pre attached gears + 2 motors. Product is excellent and should last for the lifetime of the vehicle. Glad I found these before dropping alot more cash on a whole new motor assembly.
