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.

    Great service but installation was tricky

    Posted by John on 26th Mar 2017

    I am fitting the replacement brass gear and motor to my Murcielago and I found the assembly to be a little complicated. I had to readjust the position of the worm gear several times as it jammed the motor once it was assembled and had to cut down the shaft by an additional 1mm due to the same problem. Still a great fix for the cost but not a simple job -- response -- Thanks John, would certainly love to see pics of the Lamborghini! We're always a phone call or email away if you need assistance. I know this is a bit tricky but I guess Ive done so many of these now I can do them blindfolded! Yes you do want the brass gear concentric to the shaft, you can slowly rotate it and visually pick the best position to make it sit true on the shaft. It doesnt need to be perfect but close is good. Not sure if the Lambo version is slightly different than the GM truck version but definitely give a call if need be. I'd hate to ask what these cost from the dealer on a Lamborghini !

    Thank You

    Hello Paul I installed the power mirror motor assemblies that you reworked and they work great every time. They do make more noise than before but that's ok, I'm sure the noise comes from the metal to metal (brass) gear meshing where as before one gear was plastic. Thanks for all your extra effort to get these working, as you said on your web page these have a lifetime guarantee and you would make it right if there was a problem. I wish other companies were more concerned about customer satisfaction than merely profit margins. Thank  You

    Great Product

    Posted by Jim Wheeler on 8th Mar 2017

    Just wish I'd have known about the motor grounding problem. The gear went on as shown in the directions, which by the way are very good. Probably saved me a lot of time. So I just ordered the motor, but till I get it will try to isolate the unit from ground. I'm thinking maybe try nylon screws for the base. It works fine til I put the screws in the base, then wont work, and I even tried nylon washers on the screws and putting electrical tape under the base. -- response -- Thanks Jim and sorry again for the OEM motor grounding out like that. Its odd, some OEM motors have that problem, others do not. We have NEW motors with gears preinstalled, ready to drop in which are higher torque and work perfectly. I can send you some if you need them, just let me know! Paul@GruvenParts.com 404-556-6663

    Better than plastic

    Posted by Unknown on 7th Mar 2017

    Good fix if you have the right motor. Should make customers aware of flaw in OEM motor and the need for a motor that is grounded. Thanks Paul for the extra parts to make up for the omission about metal gear and OEM motor. Make sure you by new motor to go with gear. -- response -- Thanks for review, yeah we have now changed the order options so you have to get the replacement motor to remove the defective GM motors. Sorry about that.

    Works as Claimed

    Posted by Unknown on 2nd Mar 2017

    So far, so good. Just finished installing the passenger side (factory spur gear was in pieces.) Thank you for the detailed & illustrated instructions, I certainly would have been out of luck without them. Everything so far is working well, motor is definitely faster and more powerful than O.E. Will replace driver side soon. Definitely recommend the Gruven motor and spur gear if you need to repair or replace factory originals. Excellent service, shipped on time and received promptly.

    Factory should take notice.

    It is good to know there are people out there who develop a fix for GM's planned obsolescence.

    Worked perfectly

    Posted by Jamie Bass on 28th Feb 2017

    I just got the brass gear in the mail and installed it that evening. Works like a champ. Seems solid as a rock.
