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.

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.

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.

Great improvement over OEM parts

Posted by Unknown on 19th Feb 2019

These motors and gears are what GM should have put in their folding mirrors in the first place. Factory plastic gears were in pieces. Installation was pretty painless and the mirrors fold much quicker and quieter than with the original equipment parts. These motors and gears are a great value and I highly recommend them. I bought two so I would not have to deal with nonfunctional mirrors in the future.

2008 Escalade Ext Folding Mirror Motors and Worm Gears

Posted by kenwilliams44@gmail.com on 18th Feb 2019

This is the best product i have ordered, I was searching for a while before I came across your web site. The parts came in very quick. I replaced the motors and gears in about two hours. The mirrors fold in and out even quicker than before. Cadillac needs your help!!! In fact I told my neighbor about the replacement gears an he ordered them also. Awesome product! Thanks, Kenny Williams

The only and best option

Posted by Unknown on 17th Feb 2019

Buy 2 and replace both plastic gears. They will both fail eventually, and the replacement job is easy. Use a jack handle to compress the spring easily.

Just makes good sense!

Posted by Jim w/ Croghan AutoCare Wilmington, Ohio on 15th Feb 2019

These kits are a fantastic way to fix a poor design once and for all. Quality parts, excellent step by step instructions. If you have some basic mechanical skills and can follow instructions, you can fix your own mirrors. If not, recommend this product to your local independent mechanic. I agree with the other reviewers in that you should buy two, not just one. The folding speed is much greater with the new motors.

Just go ahead and buy 2!

Posted by Dan D 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...

Replaced Folding Mirror Motor and Gear

Posted by Don V. 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.

Brought my 07 suburban power mirrors back to life!!

Posted by E 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.

Easiest Installation EVER

Posted by Diana Sanchez 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!

Great Product

Posted by Barry Proctor 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.
