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).

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.

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.

    I repaired both my power folding mirrors on my 08 Escalade for 90 dollars! Say no more. The diy instructions on your web page were a great assist. I definitely would have missed the dermeling of extra space under the new gear if not for your info. Like me if you are reading this you probably checked with a dealer as to the cost of this repair. After I did I thought I would be folding the mirrors manually until I found this product. Read the diy info carefully and take your time. Lots of stuff to break if you don't. I am very pleased with he repair and highly recommend this product. I

    GM Mirror Gear & Moter replacement.

    Posted by Unknown on 19th May 2017

    Ordering was straight forward, shipping was fast. On page 15 of the instructions, compression of the spring to release the locking ring. A 24mm socket fits perfectly. When the other side breaks I will replicate this purchase.

    I had the part installed in less than an hour. Shipping was a little slower than expected but it arrived before the weekend so I have time to take care of it.

    spur gear

    Posted by Unknown on 17th May 2017

    The metal spur gear works great,a lot better than that cheap plastic that GM uses.60 dollars for the part's and freight versus 600 or more.

    Easier than you think

    Posted by kevin hearn on 12th May 2017

    Great product. I have a 2011 Cadillac Escalade Platinum, and the plastic mirror motor gear cracked. I was a little apprehensive about the process, especially the spring removal. However, I was able to hand compress the spring using a 1" socket. It would be easier with a 1" pipe and could probably be done with a piece of pvc or pvc coupling. The disassembly process on my Escalade was different from that of the Chevy/GMC in the PDF, but was able to figure it out. Basically, you need to remove the chrome lower cover prior to upper painted cover. The trickiest part was popping the mirror clips out to remove it. Oh, and don't be afraid to bend the steel around the motor housing to get it off, those 4 tabs hold really well and can be bent back.

    Very Satisfied

    Posted by Patmico on 28th Apr 2017

    I was very satisfied with the product. I agree with other reviews about ease of making some mistakes along the way. I made a mistake and determined what I did wrong. Luckily taking the mirror apart the 2nd time is much faster. I anticipate needing to change the other mirror motor/brass spur gear in future. The repaired mirror works very nice. Thank you.
