** 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.

    awesome precision made parts - thanks

  2. 2008 GMC Driver Side mirror motor and drive assy. 5 Star Review

    Posted by on 9th Jun 2019

    This is my second motor and drive assy. The first one was for the passenger side mirror several months ago. This assy. has worked so good that when the drivers side motor went out I ordered one for the driver side. I am very pleased with the quick response time in ordering the parts, and also how good the part is.

  3. Works better than factory gears 5 Star Review

    Posted by on 7th Jun 2019

    Had one mirror not working! Ordered a set for both mirrors with the gears attached to the shaft, new gears work smoother and faster than factory. Follow the pictured instructions precisely when you get to compressing the spring, use a large socket and your drill press to compress the spring turning the retainer with a large pliers. Very pleased with the replacement parts and a lot cheaper than a new mirror.

  4. excellent product 5 Star Review

    Posted by on 5th Jun 2019

    The instructions were very thorough and the high quality photos were a big help! The process isn't too difficult. It will require some time to get through the first one so don't attempt it in a hurry. I had good luck with a socket on the spring retainer. I drilled a hole in a piece of wood to hold the worm gear shaft straight while the epoxy set up overnight. That worked real well even though it wasn't perfectly squared. The extremely tiny amount of wobble still functions perfectly. I'm a gruvenparts.com fan!

  5. Perfect fit 5 Star Review

    Posted by on 30th May 2019

    The motor and gear received was a perfect fit for my broken mirror gear and 100% better than the garbage GM installs on these expensive vehicles.
    Installation was by no means easy even with the instruction but with time and patience you can do it.

  6. Decently tough install but definitely worth it 5 Star Review

    Posted by on 29th May 2019

    The installation was not as easy as the instructions might make it sound. However, part of that was due to not having the proper tools to compress the spring. I was extremely resourceful and found a few things to help that part out. It was by far the toughest part of the install.

    Gear and motor is definitely upgraded now. I only did one side and the new side is much louder and faster than the other. Overall, I'm pleased as I regained the functionality and didn't have to pay a shop to do it.

  7. Mirror replacement gears 5 Star Review

    Posted by on 21st May 2019

    The instructions were a little confusing to me. However, the clear pictures helped me to figure out what had to be done. The first mirror was slow and deliberate but the second one was much easier.

    I used a vice to remove the spring retainer. I used a socket to collapse the spring then used a slip jaw pliers to turn the retainer. Then I slowly opened the vice while it retained the spring.. Installation was done the opposite using the vice to collapse the spring and using the pliers to turn the retainer. Be sure to use a vice with vertical jaw height to keep the unit straight when collapsing the spring so it does not pop out.

  8. great product 5 Star Review

    Posted by on 21st May 2019

    Really good product, much better than the cheap plastic ones that originally come on the mirrors. Cheaper than buying a whole new mirror.

  9. Great Product. 5 Star Review

    Posted by on 8th May 2019

    Great parts. Pay attention to the install instructions. Not for the novice. Not a quick in the driveway install. Took a total of 2 1/2 hours for me and I'm a master mechanic. Motor is faster than the OEM, but is not a problem. Saving the parts for the passenger side until it breaks. Bought the motor and assembled gear for both sides, but only the LH was broken now.
