GM Power Folding Mirror Repair Kit (Billet Steel)

Stop replacing $1,000 mirrors with the same flawed parts. The factory power-folding mirrors on GM trucks and SUVs fail because of a single, inexpensive plastic gear. When that gear cracks, dealers charge upwards of $700–$1,200 for a full mirror assembly that carries the exact same defect.

GruvenParts.com provides a permanent, engineered solution: high-strength Billet Steel gears and high-torque motors designed to outlast the vehicle.

The Engineering Gap: OEM Failure vs. GruvenParts Solution

Feature	OEM Factory Unit / Boost Auto	GruvenParts Billet Solution
Gear Material	Thin, fragile plastic spur gear.	High-strength Billet Steel (integral spiral shaft).
Failure Mode	Fatigue cracking from age or minor impact.	Virtually indestructible; tested to 5,000+ cycles.
Motor Specs	Low-torque; prone to burnout.	High-torque custom motor for smooth operation.
Grounding	Externally grounded (Incompatible with metal).	Internally grounded to prevent BCM short circuits.
Cost	$700 - $1,200 (Full assembly).	Under $100 (DIY Gear/Motor Kit).

Critical Technical Note: Why the Motor Matters

You cannot simply install a metal gear onto the factory GM motor. The OEM motor circuit is not designed for a conductive metal gear; attempting to "mix and match" will short out your Body Control Module (BCM). Every GruvenParts kit includes our custom-engineered, internally grounded motor to ensure electrical safety and increased torque.

Choosing Your Repair Path

Path 1: DIY Gear & Motor Kit The most cost-effective choice for those comfortable with a workbench repair.

Includes: 1 or 2 Billet Steel Gears and High-Torque Motors.
Best For: Owners looking for a permanent fix at the lowest price point.
Compatibility: Fits 2007–Present GM Non-Tow Mirrors (Silverado, Sierra, Tahoe, Yukon, Suburban, Acadia, Traverse, Enclave, Escalade).

Path 2: Pre-Assembled Drive Unit (Core Exchange)

Skip the internal assembly and swap the entire drive unit.

Includes: A fully rebuilt motor drive unit with the steel gear and motor already installed and tested.
Process: Requires a $30 core deposit. Send us your rebuildable old unit to receive your refund.
Note: Due to high demand and core availability, lead times can vary (approx. 4–6 weeks). For the fastest turnaround, you may send your unit in for a same-day rebuild.

Expert Installation Tips & FAQ

To ensure a successful repair and protect your vehicle's electronics, please review these critical requirements before beginning your installation:

The "No-Mix" Rule (Electrical Safety): Never attempt to install the Billet Steel gear using the original OEM motor. The factory motor is externally grounded; using it with a metal gear will create a short circuit and permanently damage your Body Control Module (BCM). You must use the internally grounded motor provided in our kits.
Mirror Type Verification: These parts are specifically engineered for Standard (Non-Tow) Mirrors. If your mirror extends outward for towing, these gears will not fit. Click here for our Towing Mirror Gear Page.
2014+ Pickup Differences: If you own a 2014 or newer Silverado/Sierra, the mirror frame plastics differ from earlier generations. While the internal drive unit is identical, the housing disassembly requires a slightly different approach. Please refer specifically to our 2014-2018 PDF Guide.
The "Core" Condition (Option 2): If purchasing the pre-assembled drive unit, your returned "core" must be in rebuildable condition. We can only accept units where the motor or spur gear is the point of failure. If the main plastic housing or frame of your drive unit is physically shattered, it cannot be rebuilt or refunded.
Tool Tip: We recommend having a basic set of trim removal tools and a small socket set. Take photos during disassembly to ensure wire routing remains clear for the re-install.

Who would have thought.....

Posted by Brent Wann on 20th Apr 2018

Who would have thought that a tuner shop would have a decently priced owner replacement/upgrade for GM pickup power folding mirrors that have died? I don't remember how I lucked onto their site, but Gruven is the best. I finally bit the bullet and ordered a pair of replacement motors with the pre--assembled gear shafts for my '09 GMC Sierra 1500 Texas Edition. The gears failed about three years ago. I had looked on eBay for some replacements, but couldn't bring myself to pay the prices for used sets not knowing if they would work, or the questionable aftermarket units. Then I found Gruven. I received my motor/gear sets and had a free day to do the replacement. The online instructions with pictures were extremely helpful. However, I did find that I couldn't remove the mirror glass following their instructions. Only one tab was accessible, but there was no way to pry it up according to the instructions. I was able to remove the mirror glass by using a fairly wide plastic door panel removal tool by placing it beneath the bottom of the glass and the mirror housing. I then pried up on the glass while pushing from the back, and the glass came out very easily. Yeah, I know I could have easily shattered the glass, but that worked for me and was the only way the glass was coming out. I did have one problem with the shafts on the gear sets. On both gear sets one end of the shaft was slightly larger in diameter preventing the bushing from sliding on to the shaft. The other end was fine. The bushing fit on perfectly. Not a big deal for me. I chucked each one up in my drill press and used some 2000 grit wet/dry sandpaper to polish the oversized end down until it had a good fit. Everything went back together good. Do pay attention to how the parts come apart and try to mark their orientation to each other. I ended up removing the first one I did to reorient the internal parts as it was bound up and the motor got blazingly hot trying to move the mechanism before I unplugged it. No damage done though thanks to the excellent materials. All in all, I am extremely happy with the motor gear combo set. If you have or have access to the necessary tools and equipment, it is not to challenging of a repair, but it can be time consuming. I recommend it

Fix your dreaded GM fluttering mirrors

Posted by Jim on 2nd May 2018

The parts came quickly and I got to work after reading the online directions carefully. There were quite a few steps but everything was a piece of cake. I'm very happy that the mirrors are good as new working flawlessly. Don't hesitate, You Can Do It!

Excellent parts selection and customer service

Posted by John on 25th Apr 2018

With the help of Paul I was able to get the right part even after determining I needed to make an exchange. Very accommodating for a DIY guy. Thank you.

Amazing difference

Posted by Richard Joslyn on 25th Apr 2018

Took me a little while to figure out the installation. Videos online left out some important details. Once I got it installed I couldn't believe the difference over the factory version. The mirror moves in and out a lot smoother and faster. Only problem now is I want to replace the other side, even though it's not broken, because you can definitely notice the difference.

Fantastic! Huge for morale

Posted by Dano on 25th Apr 2018

Purchased 2 of the gears to replace broken ones. The DIY guide was a treasure, really helped a a lot. One comment is that detaching the mirror from the mount could be more in detail . Other than that the product and accompanying material was amazing.

GM Folding Mirror Upgrade Kit Works Great!

Posted by Steve on 19th Apr 2018

High quality kit, everything fit perfectly, instructions were clear and very detailed. This is a great way to fix folding mirrors that no longer fold. I purchased the Pre-attached kits and it took about 2 hours to do each side. The hardest part was getting the motor box apart, but the second one was much easier than the first. I have a milling machine which made it easy to remove the spring. A drill press would work, too. My wife is much happier now, too!
