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.

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.

    Installation

    Posted by Donald on 26th Aug 2019

    I read and re-red the instructions before installation. The instructions were very detailed, and I installed the motor and gear assembly in less than an hour the first time. The mirror worked great. I am ready for the other side to stop working and I will repair it easily.

    Mirrors Fold With Authority!

    Posted by Kevin in Chandler, Arizona on 23rd Aug 2019

    The RH mirror on our 2013 Tahoe stopped folding about a year ago. Came across Gruvenparts while searching for a replacement nylon gear. Ordered the Motors and pre-assembled brass spur-gear/shaft assemblies. Took about 1-1/2 hours to do the RH mirror as I went slowly/carefully. Sure enough, the white nylon gear was in pieces. After a thorough cleaning to remove the smaller gear pieces and re-lubing with white lithium grease I re-assembled the mechanism and gave it a try before attaching the rest of the mirror. The mirror works better than new and best of all, it'll run for years thanks to the brass spur gear. Doing the RH mirror this weekend. Thanks for such a well-made, robust solution!

    Great product

    Posted by Unknown on 18th Aug 2019

    Had the left mirror replaced twice an d right mirror replaced once on 2010 GMC Denali; broken (plastic) pinion gears. $900 dollars per mirror. This product solves that problem forever for $50/mirror. Easy install for any backyard mechanic.

    Replacement brass gear & motor

    Posted by Santo M Fontana on 12th Aug 2019

    This is an outstanding replacement part which exceeds the OEM plastic gear. The brass gear already mounted on the worm gear is the way to go. Cost of the part is reasonable & shipping was fast.

    Better than OEM

    Posted by John Neu on 6th Aug 2019

    I purchased the Option 3 assembled motor unit for GM mirrors which fold in and out. As the Gruven website states, they provide a brass gear, unlike the plastic gear which GM installs in the motorized mirrors. Just installed it today (actually had it installed), and I’ve never seen the mirror fold in and out in such a powerful manner. The part carries a lifetime guarantee. Well worth the price, and a phone call to Gruven puts you in touch with a real human who answers the phone and is very helpful. No menu choices to play thru. -- Response -- Thanks John! Yeah no menu choices lol its just my cell phone. I hate menu choices as well, so frustrating. If i dont answer please do leave message and I will always call back. Take care and let us know if you need anything else. Paul@gruvenparts.com

    Unbelievable Service!!

    Posted by Ben Garcia on 20th Jul 2019

    I bought the gear and motor. I took everything apart and found that I couldn't take off the motor cover as I don't have a vise. After a few hand jabs with a screwdriver, I contacted GruvenParts. Paul responded and just offered to put it together for me!! I sent the parts to him, and he had them installed and on their way back to me in minutes after he got them!! Unheard of service !!! I'm actually looking forward to the other side breaking downs!! But, next time I'll get the whole thing assembled....
