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.

    Better than OEM

    Posted by Scott B on 16th Jun 2025

    Installation would have been a real puzzle were it not for the excellent step by step video tutorial. when all done and the mirror rotated smoothly and quietly, I knew I'd made the right decision to go with Gruven Parts

    Folding mirror motor/gear assembly for GM

    Posted by Michael J Hoeft on 8th Mar 2025

    Folding mirror replacement motor & gear assembly for my 2019 GMC 1500 Sierra Denali is a very nice upgrade over factory installed plastic. Emailed Paul a few times with questions and he responded quickly with good advice. Would recommend this upgrade to anyone with a similar situation. Replacement mirrors from GM are over $1,000 each, and they don't retail replacement internal parts.

    good overall.

    Posted by Unknown on 8th Feb 2025

    Motor and gear works well but very loud when actuated compared to the stock parts. Still, happy with the quality of the parts and feel they should last the life of the vehicle.

    These work great.

    Posted by Mattox on 17th Jan 2025

    My passenger mirror quit folding on my 2012 Suburban, so I bought the 2 piece set since I didn't want my driver side moving slower than the new one. Glad I did, because the driver side plastic gear was cracked too, it just hadn't broke fully yet. These took me about an hour to replace each side, so a bit over 2 hours for the set. I'm glad I went this route vs buying an aftermarket mirror. Watch the install video before hand, it is helpful.

    Works and lasts

    Posted by Unknown on 7th Nov 2024

    Ordered the kit, have replaced several plastic geared motors. These are metal gears so should last the life of the vehicle.Not going to lie, while fairly easy to install they are not the easiest. Some mechanical ability is required, but i do like them and for me it is now a done deal. Chances are the parts will now outlive me.

    Great customer service and great product

    Posted by Pete Reeser on 2nd Nov 2024

    After ordering the motor I was informed that Gruven did not have a core motor for rebuild. Then arrangements were made for me to ship a motor that had been previously removed and in two days I received the rebuilt motor that works perfectly.

    This is what GM should have done!

    Posted by Rod on 7th Oct 2024

    Great replacement parts for a very poorly designed plastic gear set, My Chevrolet avalanche was 2 weeks old just off the dealer lot and the left folding mirror failed, the dealer put a complete new mirror on and here again the left mirror failed as the plastic parts "gears" failed again. After doing a lot of reassert I found this Company WWW. GruvenParts.com that makes QUALETY replacement parts for repair of this plastic junk gear set. With a reenable skill set and a Trox 10 and 20 bit can with some other things like a bench vise a few other common tools can save them selves several hundred dollars on parts an labor. Also you folks with electric seats you are in same boat yep! plastic gears! WWW.GruvenParts.com has the replacement parts also for GM plastic!
