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.

    Very good quality, Easy Install

    Posted by Andrew on 10th Jan 2018

    Part came timely, very simple install utilizing the step-by-step picture guide provided by Gruven. Only material addition I would suggest is to double-triple check the order and orientation of all the internal parts as you're taking it apart (it took me a couple of re-installs before getting everything to operate perfectly). Other than that, very simple piece to replace at a fraction of the cost for a new mirror...

    Worth every penny

    Posted by Bobby L Padgett II on 28th Dec 2017

    Wanted to compliment you on your STRENGTHENED SPUR GEAR FOR 2007-2014 GM TRUCKS FOLDING MIRROR ASSEMBLY I am not the most mechanically inclined person (didn't get the gene from my dad), but I just finished installing the pair of the spur gear and hi torque motor on his 2009 Silverado 1500 LTZ. This was a total pain repair, but your instructions were very good. It took me about 2 days to do the repair (including cure time on the epoxy), and the mirrors fold faster than anytime since I got the truck from my dad almost 3 years ago. I now feel confident enough that I could do this repair for anyone. Thank you for a quality part.

    Posted by Unknown on 11th Dec 2017

    I've had 3 different trucks the same bodystyle with the same failing folding mirror motor gear. Thank you for this product and for creating a simple affordable solution for a common issue with these trucks. Will definitely recommend to everyone.

    Definitely Better Than OEM Plastic

    Posted by Mike on 9th Dec 2017

    I ordered this spur gear and motor to replace the plastic OEM spur gear. Initially the motor would only operate the power mirror a few times and then stop. After trying some troubleshooting with Paul I sent the motor back so he could file the motor teeth down a little When I got it back and installed it the motor operations 100% of the time for a week now. Thanks to Paul for getting it to work properly. I'm giving 4 stars instead of 5 just because I had to send the motor back for rework.

    Paul is a rockstar!

    Posted by Christian Otto on 6th Dec 2017

    While this is a product review, I'd like to start this with the exceptional customer service offered by Paul. He was very fast to reply to my emails, offered a call to answer even more questions I had. Paul went above and beyond to assure everything is working as it's supposed to. This is so very much appreciated! Now to the product itself: 100% satisfied. I will buy it again if the other mirror breaks down. Everything fits and works as it is supposed to. The DIY guide was super helpful.

    Much improved part

    Posted by Quentin on 5th Dec 2017

    I didn’t install it yet (couldn’t find a tool to compress the spring). I like The fact that the spur gear is brass instead of the brittle plastic.

    Product great, but customer service far above expectations

    Posted by Jim Senft on 3rd Dec 2017

    I followed the well-written instructions to install the much needed replacement parts. I must have done something wrong, and Paul bent over backwards to assist me and getting my vehicle back on the road. I would venture a guess that one will not find a more proactive customer service philosophy than what Paul provides. THANK YOU THANK YOU THANK YOU for help!!! And everything is working better than new! -- response -- Thanks Jim, let us know if you need anything else. 1st and foremost we want to make sure everyone gets their mirrors working again properly without the need to visit GM dealer for overpriced plastic bits that will break. This should fix it forever and definitely call me again if you need to! Paul@GruvenParts.com
