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.

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.

    motor and gear upgrade for GMC mirrors

    Posted by Brad MIller on 12th Aug 2024

    Just replaced the broken motor/gear assemblies for the electric mirrors on my GMC Sierra. Fantastic upgrade from the broken plastic OEM parts. First replacement time was about and hour with most of that just trying to figure out how to get the actual mirror separated. Second mirror too half that time. Thank you for the parts that should have come from the factory.

    Better than factory

    Posted by FRED on 11th Aug 2024

    The overall replacement parts resolved the broken mirror rotation in/out at a fraction of the cost to replace the oem mirrors. Toughest part of the job is not breaking any of the plastic frame tabs. Use some WD40 on never before removed mirror mounts to facilitate easier tab release from grim build up. Video instructions help understand the removal and imdtallation process. Works well, fast open and close!

    These parts are better than OEM.

    Posted by Rob U. on 10th Aug 2024

    These parts are better than the plastic OEM. The video on YouTube was helpful, but did not match my 2014 GMC Denali mirror assembly. It took me a while to figure out how to dissasemble and a broke some clips in the process. reassemble was easier once i knew the order. My model is easier to dissasemble than the previous model [once you know how]. These parts are plug and play. There is no modifications required {no grinding]. The mirror opens and closes faster than the original. The can still be manually moved forward and backwards as before. I now know how to do the other mirror when its plastic gear breaks ;-)

    upgrade

    Posted by Bobby on 24th Jul 2024

    The mirrors on my 2016 Silverado stopped responding to the fold in/out. Took it apart and noticed the plastic gear had shattered after almost 9 years of use. The new metal gear is solid and easy to replace, trick is taking the mirror apart with all the plastic clips. Definitely recommend, be nice if they added a small pack of grease with the item though.
