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.

Application & Fitment

This kit is designed for Standard (Non-Towing) Power Folding Mirrors on the following 2007–Present models:

  • Chevy: Silverado, Tahoe, Suburban, Avalanche, Traverse.
  • GMC: Sierra, Yukon, Denali, Acadia.

Warranty: This product carries a Limited Lifetime Warranty. If the gear or motor fails under normal operating conditions, we will replace it free of charge—you only pay shipping.

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.

    Spur gear and motor

    Posted by Unknown on 29th Oct 2017

    This is the second time I ordered the spur gear and I received the motors with it this time. The motor shaft was just a little too long and needed to be clearance little bit. After which everything work perfectly. -- response -- Thanks for honest review and sorry they originally didnt ship the gear with the motor. Not sure why that happened but we got it resolved quick. Regarding motor shaft length - we have noticed SOME units require slightly longer motor shaft than others. So, we make the motors with the longest possible shaft length to accommodate the variance in the GM units. As you have done, you can slightly grind off a tiny bit of shaft if this is case. Or, what I usually do when I repair them here is just extend that hole for motor shaft using a 1/16" drill bit, thru the black plastic basket. This will allow motor shaft to poke down a bit farther if it wants to. Paul@GruvenParts.com

    Works better than OEM!

    Posted by D Parker on 26th Oct 2017

    Purchased the gear and motor and installed the parts exactly like the directions instructions. I used the exact epoxy and lubricant in the instructions. The mirror actually folds in and out slightly faster than the OEM mirror. Great replacement part for my 2007 Suburbon LTZ.

    My mirror is GRUVEN !!!!

    Posted by ken jenkins on 24th Oct 2017

    Good strong parts, at first I thought that it was going to be hard, but I follow the instructions and it was a breeze, and make sure you have the tools, I used the tools that it called for and I bought a spring compressor tool and it only took me 2 days, only because I had to wait for the JB weld to dry, I truly recommend this product.

    Great service, great part. Cost effective fix.

    Posted by Jennifer on 16th Oct 2017

    The part arrived quickly. The instructions for installation were great!!! The mirror was disassembled and the new part put in under an hour. The mirror works again and sounds so much better. The mirror opens and closes smoothly and much faster than the other side that has not been replaced yet.

    Fantastic upgrade !!

    Posted by Andrew Donnelly on 11th Oct 2017

    This was very easy to install with the instructions on the web site. I saved my customer over $700. The repair for both mirrors took about an hour. The only thing that would have made this kit better would be to include the epoxy. I will be using these parts for repairs at my shop.

    straight forward repair

    Posted by Ray H on 2nd Oct 2017

    The repair is not difficult. The instruction they emailed me worked great. The kit comes with the two new brass gears, and two new electric motors. The shafts were a bit longer on the new motors and I had to cut it down a little. Both mirrors now work again! Strangely, the drivers side folds faster than the passenger side. Very happy they work again, and at a very small fraction of the dealer costs.

    Was a bit of work to install but it works good and is faster than the factory mirror. I advise it . -- Response -- Thanks for the review !
