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.

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

  • Chevy: Silverado, Tahoe, Suburban, Avalanche, Traverse.

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.

    perfect stripped gear solution

    Posted by Chuck Avery on 10th Oct 2022

    I purchased these metal folding mirror gears to replace the stripped and broken cheap plastic ones that came factory on my chevy silverado. Remember though don't just buy some metal gears off the internet. Buy the Gruvenparts gears and motors together for your factory motors will not work with metal gears it grounds out. Gruvenparts has the replacement motors that works perfectly with their metal gears.

    Great product, saves a ton of money

    Posted by Dave F on 4th Oct 2022

    Wonderful product. My mirrors work better than new with these gears. It's hard to believe GM used such crappy little plastic gears, but I guess they saved 50 cents per truck, so it all adds up, LOL. These new gears are a bit tricky to install, but good instructions on the site here. Be sure to follow instructions carefully, and use proper tools. Total installation, both sides, took me between 3 to 4 hours.

    Second purchase

    Posted by Alan Laib on 2nd Oct 2022

    First motors/gears lasted 3 years. Not sure what happened to the first set, but the motors roasted themselves, the commutators/brushes were burnt beyond use and motor end-play was about 1/4"upon removal. New ones installed yesterday, New gears are one piece instead of brass which is alright. Fingers crossed these will last past the old set.

    Best Fix for GM POWER FOLDING MIRRORS Failure

    Posted by Darryl Meyer on 19th Sep 2022

    I ordered the 2 gears + 2 motors option to fix both of my power mirrors on ‘09 GM Yukon Denali. Passenger side was very easy fix following the Gruvenparts installation video. Power Mirror works great now. On Drivers side mirror I discovered the plastic portion that actually holds the spur gear was broken and can’t hold the spur gear in position. I plan to try repairing the plastic part and then install the new gear & motor. The broken plastic is the cause of failing the Driver’s mirror. I am confident the mirror will be perfectly functional once I repair the plastic assy. Too bad GM used plastic for this particular part of the power mirror unit. I sent an email to Paul @ Gruvenparts and actuator an immediate reply from Paul. Great SERVICE!

    My Denali was having issue with BOTH side folding mirror. The motors stopped working. I was just going to replace the mirrors like everyone does. I found this site and thought why not give it try. The work that was done is flawless. The side mirrors work perfectly now. No issues at all. Do not hesitate to send you side mirrors in to have this done. You will not be disappointed.

    2009 Silverado Folding Mirror Repair

    Posted by Marty Martinez on 14th Sep 2022

    Ordered the motors and gears for my 2009 Silverado. Everything arrived on time and without issue. The video and PDF instructions are a great reference. I probably could not have made the repairs myself without this reference material. It took me about 3 hours to repair both mirrors. They work great! Definitely better and much affordable that purchasing new mirrors. Thanks.
