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.

    Great replacement!!!

    Posted by Ken B. on 14th Apr 2018

    I ordered the spur gears already attached to the shaft so I could fix the mirrors without waiting 24 hrs for epoxy to dry. The instructions provided were great. Everything went smoothly and the mirrors now fold again. I feel the metal gears are far superior to the original plastic gears which get brittle and break. This was a much cheaper alternative to replacing the mirrors, especially when your mirrors have ALL the options.

    Complex Installation Required

    Posted by Bob Fries on 13th Apr 2018

    The motor and gear/worm gear assembly were as advertised and fit well into the assembly. However, the endplay in the replaced gear/worm gear assembly allowed the new brass gear to rub on the plastic housing. Although the instructions said to just move the bronze bushing to limit the endplay, a small force would just push the bronze bushing back to its original position. I added a small nylon washer to limit the endplay; then it worked fine. The .pdf online instructions were excellent with good, clear pictures and many helpful tips. One suggestion is to add another arrow on the picture on page 11 to show the exact location of the spring tabs that hold the cover in place. The first top clip is very easy to see above the hinge area; the second tab on my 2008 Yukon was located inside the mirror cavity, not below the hinge area as indicated.

    It works!!!

    Posted by Gordon Taylor on 6th Apr 2018

    Even with 5 Stars, I'm going to be slightly critical. 1) Alignment can be a little tough after you take the time to strip down the parts to clean and lubricate with new grease. Could use a little better description on reassembly, but you'll figure it out with a little effort. I actually reassembled mine back on the mirror base as far as the loose parts and then held it together while taking it back off to reattach the spring assembly. 2) It would be a good idea to mark the motor base on the mirror base for hole allignment prior to disassembly? Asside from those 2 issues, once I got it all worked out, I couldn't wait for the other side to break so I could replace it. Oh, wait a minute! I didn't wait for the other side to break. I went ahead and ordered for the other side anyway. Order for both sides and replace them both at the same time. It will save you some bucks!!! Great product! Can't wait for some more innovative ideas that will help keep the beast in better condition than GM produced!!!

    Fantastic, thank you!!

    Posted by Joel T on 19th Mar 2018

    Took me a couple of hours, only because I did not have a large enough vise to compress the spring. A quick trip to the hardware store and I was able to compress the spring with some threaded rod and nuts/washers on both ends. I did one side and will do the other if / when it goes out. Don't forget to check orientation of the assembly, I also missed that one and had to backtrack a bit. A great product and I will recommend to my friends with these types of GMC mirrors!!

    Very Satisfied!

    Posted by Joe on 16th Mar 2018

    Had the driver side mirror OEM gear go out on me a few months ago. Finally got around to ordering these parts (for both sides) and installed them last night. All together it took about 3 hours, 2 for the first and 1 for the second. I don't do a ton of this kind of work so thing were a bit slow going at first as I took my time to figure it out. The second mirror went much faster. The end result is excellent and very satisfying having them both working the same. The new motors are noticeably faster and operate more smoothly. One might even call them "zippy".

    great product! way better than factory

    Posted by r.dana.smith@msn.com on 8th Mar 2018

    Had these replaced on both sides, only took about an hour. One of my mirror gears was broken, but I went ahead and did both to save time since it would prob break in the future. They were so well!! I have full confidence that these will last forever

    AWESOME!

    Posted by JSS on 3rd Mar 2018

    Fast procedure. Only took me about ½hr. Quality motor and gear. Works twice as fast as the other mirror now. Definitely coming back when/if the other mirror gears break!

    2010 Yukon Denali Mirrors Fixed!

    Posted by TuckLANE on 2nd Mar 2018

    Great easy to follow instructions. It was nice to replace plastic with metal. Other than drying time for the JB Weld it took less than an hour per side. Both mirrors work great. -- Response -- Thanks for the review. Please note we do now have the integral brass gear pre-attached to main spiral to delete the epoxy step! I know that was just released, you may not have seen it yet. Take care, Paul@GruvenParts.com

    @011 Denali mirror

    Posted by Lex P Christensen on 1st Mar 2018

    Replaced the gear and motor and had no problems. It's a little more noisy but that is to be expected with metal gears. Thanks.
