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.

    precision product designed to solve a defective OEM design

    Posted by John on 16th Jul 2019

    The machined products are extremely well made and fit perfectly. The online instructions are detailed and well prepared. Most importantly, Paul at GruvenParts was very quick to respond to my installation question since the 2010 Buick Enclave mirror came apart in a slightly different manner then the Traverse.

    Everything I Expected

    Posted by Unknown on 15th Jul 2019

    Solid product. Direct replacement for the cheap plastic gear that GM in their infinite wisdom thought was a good idea. Purchased the pre-assembled motor and gears to save time, and as insurance if the old motors were bad also. Money well spent. Thank you Gruven for offering such a quality product

    Gears worked perfectly

    Posted by Brandon on 12th Jul 2019

    The first one took an hour, the second one about 20 minutes.

    Worked perfectly!

    Posted by CJ HOIEN on 10th Jul 2019

    My folding mirrors have never worked. Bought the truck used. Dealer disconnected harness to "hide" the issue. Found your product and had the confidence, after reading the instructions, that I could do the repair. First mirror took a while. Second mirror took less than 30 minutes. Read ALL of the instructions before you start. Follow the instructions!

    great product

    Posted by CC on 10th Jul 2019

    Install takes time. Mainly the spring as I didnt have a vice so I used a 1in piece of PVC and body weight. I bought 2 pre attached gears + 2 motors. Product is excellent and should last for the lifetime of the vehicle. Glad I found these before dropping alot more cash on a whole new motor assembly.

    EASY To install

    Posted by Sam Swaringen on 6th Jul 2019

    I purchased the whole motor assembly. I haven't had it installed long but I can tell from comparing to the passenger side, that the driver side is solid and probably will be for as long as the truck lives. I will be purchasing the motor assembly for passenger side as well. Thanks to the Gruven team for the innovation.

    I've been driving around with busted mirrors for years....

    Posted by Steve E on 5th Jul 2019

    Damn if these things didn't work and saved me 1400.00. I hadn't searched for a solution for my power mirrors that were no longer folding on my 09 Tahoe in 4-5 years and I stumbled into Grueven Parts about a month ago. I went with option 2 , it took my custom shop around 2 hours per mirror and they are working great. The fold in and out faster than the factory version. There were no issues on the shipping and great communication from Paul. Thank you sir, awesome product.

    Gruven parts are great

    Posted by David Learn on 24th Jun 2019

    I received half of the parts originally ordered, but upon contact with Paul from Gruven he was able to rectify the issue quickly. Once I received the needed parts I was able to replace the failed parts with the excellent parts from Gruven. I also wish to state that the DIY instructions from the web site are excellent and easy to follow. I would recommend these parts for anyone that needs to replace their non-functioning powered mirror gears. -- Reply -- OK thanks, and sorry about the original mix up David !!!

    Excellent

    Posted by Dale Wilson on 24th Jun 2019

    Brass gears are solid, will last a long time New motor and gear assembly operate much quicker than the old setup with the plastic gear. I'm completely satisfied.
