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.
  • Cadillac/Buick: Escalade, Enclave.

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.

    Quality parts

    Posted by Eddie Tom on 28th Nov 2017

    The product is quality and installation was easy. Only difficult part is waiting for the epoxy to set. Wished they would had included some grease for the installation at this price. Overall, still very happy! -- response -- Thanks Eddie, glad you got it fixed. I will look into where to get small qty of gear grease to include in the kit, that is a good suggestion!

    SPUR for GMC Mirrors

    Posted by Nick Grassi on 28th Nov 2017

    EXCELLENT product. Easy install and saves big $$$. Price a GM replacement mirror with all the bells and whistles... -- response -- Thanks Nick. Yep there is NO point in wasting more $ on the GM units. Not only would you need to tear off the inner door panel to put in, you spend a boatload of cash and get the same plastic gear that caused all this in the 1st place. Incredible to think a truck this wide would not be build for at least some contact on the mirrors without breaking ... Paul@GruvenParts.com

    Assembly was quick and easy.

    Posted by Rowland Morrison on 27th Nov 2017

    I got the pre-assembled unit. It was a 30 minute project and worked great. I did the drivers side, and would gladly do the passenger side the same way if it stops working. -- response -- Thanks Rowland, we appreciate the honest review. Let us know if we can assist when/if the other side goes out.

    1st Class customer service and product

    Posted by Unknown on 19th Nov 2017

    The parts are top quality upgrades/replacements, and the support provided after the sale is as good as you’ll find anywhere. I ran into a couple issues/questions along the way and they were responsive via email even after hours.

    Worked like a charm

    Posted by John C on 7th Nov 2017

    The parts worked just as described....however probably the best part was the detailed instructions on their website on how to put the new parts on. I only had one mirror that was not working properly but since I figured it was only a matter of time before the other mirror stopped working (plus after I saw the repaired mirror closed twice as fast) I went ahead and replaced both mirror parts. It was a good thing I did since when I took it apart, the plastic gear had a crack in it and was well on its way to failing.

    Great product with great Instructions

    Posted by Duane on 3rd Nov 2017

    Purchased the folding mirror gear/motor for both my mirror's. My drivers side mirror was not working. The DYI guide is great. The cheap plastic gear from GM was broken/notched. Put in the new gear/motor and working great now. I'm sure the passenger side mirror will be going out soon, glad I bought the 2 motors/2 gears so I'm ready.
