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.

    Perfect fit, well worth the upgrade.

    Posted by Scott Bostwick on 10th Jul 2017

    Bought a set for both sides, my passenger side was busted. I installed the passenger side and it was faster than the driver, ended up going ahead and replaced the driver side too. Now they both work at the same speed. Super easy to install if you're mechanically inclined.

    Exact Fit

    Posted by Unknown on 7th Jul 2017

    The sprocket was an exact fit for a powered folding mirror on a 2007 Chevrolet Suburban. Excellent quality, made of brass. However, the motor that came with the sprocket required 1/16" to be removed in order to fit. I recommend viewing the YouTube video prior to ordering to determine your capability to replace the sprocket. -- response -- Thanks for this review. In some cases, a slight bit of trimming may be needed on that motor shaft. Some of the black plastic baskets have deeper holes in them than others. Rather than trimming the motor shaft, you could also just use a 1/16" drill bit and extend the hole in the black plastic basket under the motor to allow motor shaft to engage farther. Glad you got it working, as always call or email me if any issues. Paul@GruvenParts.com

    Worked as advertised

    Posted by David Clay on 4th Jul 2017

    I bought the assembly after the body shop quoted a $750. Price for the complete mirror plus $ 150 to install. I bought the motor assembly here for $200. Plus 200 for refundable core charge. The 200.00 was refunded in two days. The assembly arrived promptly with in two days after ordering. The only thing I would like would be an invoice and instructions with the part. However you can print your online invoice and there are excellent YouTube vidios. I just ordered and received my 2nd assembly for my other car.

    Posted by tim on 27th Jun 2017

    Top notch hardware. I am a VW guy and when I found the link that gruven made parts for my GM I was so happy. The parts were well built and the directions were spot on. I fixed both mirrors with the gears and motors. Very pleased and happy with this solution.

    Better than new.

    Posted by Unknown on 8th Jun 2017

    Well engineered kit. Excellent instructions. Parts need to be glued perfectly so I balanced one end of the reduction gear on the two bushings it normally rests when assembled, while glueing the brass gear to the shaft. Worked pretty good but it is difficult aligning small parts like these.
