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.

    The only parts you need to fix your folding mirror.

    Posted by Unknown on 1st Jul 2020

    Do not go and buy just the metal gear . The gears are plastic but it’s not by mistake. If you just replace the gears with metal you'll short the motor and possibly damage your computer. Gruven has the whole solution. A metal gear and a ground isolated motor. After monkeying trying to unsuccessfully fix mine for a couple of days, I was able to install Gruven's parts and get it working in 20 minutes

    09 Avalanche Right & Left complete assemblies...

    The installation video sold me the units... One suggestion would be to lubricate the plastic mirror pivot with Anti-seize.... I did and they glide like butter....Work great!

    Great Product, Tricky Instalation

    Posted by James Gray III on 30th Jun 2020

    I bought two of these, one for passenger side and one for the driver's side. I could not do the passenger side install because working with the lock washer for the spring proved to e tough. The washer got all bent out of shape in the process and I could not make it work after that. Maybe I had the wrong tools. There must be a suggested tool for this application. I then ordered option 3 for the passenger's side. Worked like a charm. With more knowledge, I did the driver's side with this product and it works 95%... I think the small degradation in performance was because I did not grind a part down smooth enough. Anyway, the part was perfect, the mechanic as not. I would recommend Option 3 unless you are very skilled and have the right tools.

    Very High Quality

    Posted by T Hunter on 16th Jun 2020

    Very happy with this purchase. The replacement gear and motor will probably outlast my truck. The quality of the parts is excellent. They should have been manufactured this way to begin with. The process to replace the parts is not too difficult if you take it step by step. There are YouTube videos available as well. If you don't have a vice, you can use a quick grip clamp available at Lowes or Home Depot. One other piece of advice: you want to mark the parts with a sharpie pen or a sharp object before disassembling them so you can line them up correctly again. This tip was shown on one of the videos. If you mess this up, you might have to reassemble the collet, gear, and spring until you get it right.
