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.

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.

    Looks like the gears for the mirrors will work fine just have to get them put in. Has got to be better than plastic.

    Gruven is the gruviest!

    Posted by Pete on 10th Jan 2017

    Thanks for making a part that actually works like it's intended and meets a real need for many consumers. Gruven saw what was needed, engineered the solution and saved us a bunch of money in the process. The installation instructions and photos are extremely good. This isn't rocket science, but it's not necessarily for the impatient or mechanically-inept, either. Most time-consuming procedure was the gear break-in and tuning. Initially, motor wouldn't turn shaft at all, but followed the excellent break-in instructions and eventually worked perfectly. Ultimately, the repaired mirror is much better than some cheap aftermarket, offshore crap and now much more robust than the garbage GM built in the first place. The fact that Gruven would spend the time and resources to develop this excellent, money-saving fix is very cool. Gotta love good old American ingenuity. Just follow those great instructions, go slowly and succeed.

    The best even when the install goes bad!!!

    Posted by Unknown on 6th Jan 2017

    It's easy to be good when things go right, the character is found when it goes wrong and it's the customers fault. I couldn't make the gear work (my fault) and Paul was there as advertised to help me through it. Both mirrors work great now, with new gears and motors. One suggestion, if you're going to the trouble to change the gears, change the motors as well. The motors are noticeably more powerful and smother. Thanks Paul for all the help.

    Great Fix

    Posted by Jason on 5th Jan 2017

    I purchased this product in order to repair my Cadillac Escalade passenger mirror. In my particular case I had the broken plastic gear as well as a broken screw that mounted the motor asy. to the base. I followed the instructions per the website and was back in service in a short period of time. Also note that another root cause of this plastic gear failure is attempting to actuate the mirror while their is ice build up. A good example is trying to actuate the mirror after you have left the car wash (winter) and the water freezes up the swing components of the mirror causing internal damage. Overall a great fix to an expensive mirror.

    worked perfectly

    Posted by Unknown on 4th Jan 2017

    Other than needing to make absolutely sure everything is reseated in place when you are reassembling the instructions are quite helpful. Product worked as advertised and I would recommend.

    Great fix for a bad GM issue

    Posted by Mike on 11th Oct 2016

    Parts worked great, follow the directions and it's easy. I had my brass gear broke in one mirror, but I turned it 120 degrees and installed the new gear from Gruven. I recommend this and will be telling others on the GM forums about this quick fix. Thanks again
