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.

    Great upgrade to an OEM Problem

    Posted by Jim on 11th Jan 2024

    After several folding mirror movement failures, I opted for the upgraded motor and gear assembly from Gruven Parts. Installation was straightforward thanks to the YouTube videos, and after the installation was completed I was utterly impressed with the smooth (and fast) operation of the new motor assembly.

    I have installed these parts before and they worked great. Have not got these installed yet. I ordered these because the other set has worked perfect. Will order again if needed.

    LONG Time Shipping

    Posted by Lea Greenleaf on 4th Jan 2024

    This is my second order from Gruven Parts and I know the quality will be there in the parts I ordered. The only problem was the shipping time. Understandably since I ordered on Christmas Day I knew there would be some delay with the New Year as well. I got a Post Office tracking number the day after Christmas. I kept checking with the Post Office but they were not receiving the part from Gruven. Finally on January 3rd I contacted Gurven to ask why and was told that the Post Office would be receiving it that day. Now on the 4th of January Gruven wants me to review the part I haven't received. As already stated I am sure the part will be excellent; just not the shipping. **reply** Sorry Lea. Orders on Christmas can take a little longer since USPS is often understaffed. This year, we all got Covid for Christmas too, added bonus! Im glad you have the parts now and sorry for the delay. Please contact me before your next order, we will make it right.

    Excellent Product

    Posted by Len Kolpak on 19th Dec 2023

    Purchased the two gears and motors. Put installation video on laptop and set it up in the garage. Followed the instructions of the video step by step and replaced the broken plastic gears and motors in the 2008 Avalanche and both work like a charm. It takes a while to disassemble the mirrors and release the spring, but instructions help make it doable. Great satisfaction in seeing them operate again. as they should.

    Bad to the Bone

    Posted by Del Hoagland on 16th Dec 2023

    I ordered the rebuilt motors for my mirrors on my 2007 avalanche. They were shipped USPS and I received them in 4 days. I reviewed the videos that Gruvenparts had online and had no problem removing the old motors and installing the new ones. The mirrors now work better than ever before. The mirrors feel solid and they fold in and out faster than before. I sent my cores back to Gruven and I just received my refund which took about three weeks. Overall this was a great experience.

    Awesome Quality

    Posted by Oscar J. on 23rd Nov 2023

    Purchased the power fold mirror motor and worm gear drive for the GM DL3 mirrors. It's worth every penny. As long as you have the proper tools on hand, Installation is a breeze with the PDF files that are provided here on their website. Took about 2hrs to do one side and about 1hr for the other and that's only due to not having the proper grinder to shave down the metal tabs on one of the parts. Highly recommend this to anyone looking to repair their DL3 mirrors.

    Great Product

    Posted by Tim McBrearty on 17th Nov 2023

    Replaced the mirror motor drive unit. Now my repaired mirror works better than the other OEM mirror........faster and quieter. The instruction video on the website was priceless. The only challenge was the R&R of the mirror glass which required some patience! Installation took about 2 hours total.
