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.

    Great product

    Posted by Ed on 28th Jul 2020

    Bought complete unit didn't feel like playing with parts , getting too old for that stuff. Replacement unit simple bolt on and go. Taking apart mirror for first time slowed things down but instructions very complete. Work great, faster deployment may consider doing other side just because.

    You May Want to Order the Assembly

    Posted by David W Goodwin on 25th Jul 2020

    The replacement parts are excellent quality--and what GM should have used to build the car, not a cheap plastic gear. I bought the pre-attached gears and motors for each side...and wish I had bought the complete assembled unit---it would have been much easier and less time consuming. This job is complex and took me a whole day--lots of mistakes, but I finally got it perfect on each side. .

    2010 silverado 2500

    Posted by Unknown on 22nd Jul 2020

    I bought the Gruven replacement motors and already assembled gears to repair my passenger side mirror motor. I bought the pair in case the other was to ever go bad.After repairing the passenger side, I was testing the new installation, and while testing, the drivers side stopped working. Jumped right on to it, and had both sides back in operations in a little less that an hour. The installation video was awesome and made the whole job a snap!

    Easy Installation

    Posted by Ben on 22nd Jul 2020

    A little tricky putting the spring back on. But if you mark everything as you take it apart, it will go back on easily. Works better than before.

    Cant say enough about how much better engineered this part is than the OEM part. Worked great and Gruven provided excellent customer service.

    Replace both motor units for the same price I would have replace 1 hole mirror (out of the dealership). Each motor took me about 45 minutes: totally worth it! Allow about a week after confirmation from gruvenparts for your order to come in Follow the instructional video, not complicated at all

    2009 GMC faulty original mirror motors

    Posted by Stephen Haworth on 13th Jul 2020

    Bought the Gruven replacement motors and worm gears to replace the faulty factory mirror motors. The parts came in within 3 days, very fast shipment. The PDF help file is very beneficial to show disassembly of mirror and installation of new motors with worm gears. The second mirror only took about 20 minutes start to finish, both are working perfectly thanks to these heavy duty parts.

    Mirror Finally Retracts

    Posted by Steve Cain on 2nd Jul 2020

    I have owned my 2009 Suburban for 3 1/2 years. The mirrors retracted when I bought it but shortly afterwards the passenger side mirror worked intermittently. Upon digging into it, I found the gear had split but I couldn't figure out how to get to it so I put everything back together and left the motor unplugged. After 3 1/2 years and not wanting to buy a whole mirror assembly I did a search to see if anyone had a fix for it. That's when I found Gruven Parts and their motor and gear set. To save time I bought the gear already assembled. The installation video was awesome and made it easier to disassemble than when I did it the first time. Got everything installed and back on the vehicle and it works great.
