Description

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.

    Much needed part!

    Posted by Maurice on 23rd Oct 2019

    My sided mirror on my 07 Silverado stop retracting in and out several months ago. I couldn't find anyone locally to repair this issue for me, the dealer might have suggest replacing instead of repairing my mirror, which means I would have to replace both due to getting a matching set, this would have cost me nearly a $1,000 or more. Long story short, paid less than $75 and did the repairs myself. Works GREAT!!!!

    The best solution

    Posted by Tim on 18th Oct 2019

    The motor and new brass gear are the best way to resolve the mirror problem. I purchased the motor and the new gear on a new shaft. The most important part was the instructions I downloaded from the site product page - very clear detailed instructions. I also found a GM Mirror Repair video clip on line. Between the two, I was able to be more confident in my process of repair. Of course nothing is as simple as it seems, but it sure wasn't as difficult as I expected. -- Response -- Thanks Tim ! And please note we do now have an official video, the link is also posted at top of the product page. One of our installers (Mike) really goes through it using 4K video and narrates it well. Glad you got it fixed and its working again.

    Excellent Product! Pre-attached gear and motor assembly.

    Posted by Jeff Wasilewski on 30th Sep 2019

    Excellent fit! Watch the videos on disassembly! Take care on releasing spring. When grinding tabs on collet make sure you grind smooth and flush to avoid binding. Not a difficult project just take your time. The pre-attached gear will save you a days waiting for epoxy to cure. Great upgrade over the stock plastic spur gear.

    Fantastic product... far superior to OEM parts

    Posted by John Olson on 30th Sep 2019

    The replacement motors and gears for my Chevrolet Silverado 3500 HD were a fantastic solution to the failed OEM parts. GM should be ashamed of themselves for putting cheap plastic mirror fold gears in a heavy duty truck. Thank you Gruvenparts for making these replacement parts the way they should have been made in the first place. Brass wins out over plastic every time! I highly recommend the Gruvenparts product! I’ve already told several of my friends who have GM trucks about Gruvenparts.

    awesome

    Posted by Unknown on 26th Sep 2019

    Works as advertised. they came in fast installation was easy thanks to the instructions provided by gruven. didn’t even have to remove the whole mirror assembly because it’s was easier when you’re reinstalling everything back together. put everything back together and it twice as fast as the old one. i’m glad i decided to go this route instead of buying a whole assembly that is just gonna go bad in a couple years.

    Better than OEM

    Posted by mark on 17th Sep 2019

    Excellent fit for aftermarket product. Glad I bought motor and gear as the OEM motor worm gear is slightly different from replacement round gear. Noticed that new gearing is slightly faster than factory movement as well. Only thing lacking was perhaps some gear lubes. All in all excellent product for price.

    Awesome!

    Posted by MB on 9th Sep 2019

    I was one of the first in line when the plastic gears were in prototype. I decided to upgrade to these brass gears and while I was at it change the motors as well. WOW! Money well spent! The gear works wonderfully and the new motor is twice as fast as the OEM one. Remember to grease the gears and everything will be smooth and quiet. These are high quality - well engineered parts that should outlast the rest of the vehicle. Don't second guess when ordering, just buy for both mirrors - you'll be glad you did!
