GM Power Seat Height Adjustment Gear Kit (Solid Brass)

Stop replacing entire seat tracks for one broken plastic gear. In 2007–2014 GM vehicles, the power seat height adjustment relies on a fragile plastic gear set that eventually strips or chips under the weight of the occupant.

When these gears fail, dealerships will only sell you a complete seat track assembly ($600–$900+). GruvenParts.com offers a Solid Brass permanent fix that replaces both failure points in the mechanism for a fraction of the cost.

The Engineering Gap: OEM Plastic vs. GruvenParts Brass

Feature	OEM Factory Part	GruvenParts Solution
Material	Molded plastic (Spur & Worm gears).	Solid Brass (Helical-cut).
Durability	Prone to stripping, chipping, and total failure.	Industrial strength; will not strip or break.
Repair Scope	Replace the entire seat track unit.	Targeted repair of the internal gears only.
Value	$600+ plus high labor costs.	Affordable DIY kit with a Lifetime Warranty.

What’s Included in the Kit?

Unlike incomplete kits on the market, we provide a matched set to ensure a "bulletproof" repair. Replacing only one gear often leads to the new metal gear chewing through the remaining old plastic gear.

(1) Helical Cut Solid Brass Main Spur Gear
(1) Solid Brass Mating Worm Drive Gear
Note: One kit repairs ONE (1) height adjuster. Each seat typically has two adjusters (Front Height and Rear Height).

Application & Fitment

This kit fits 2007–2014 GM Vehicles equipped with power seats, including:

Chevy: Silverado, Tahoe, Suburban, Avalanche.
GMC: Sierra, Yukon, Denali.
Cadillac: Escalade, DTS.

Compatible Seat Track Part Numbers: 22804417, 22804418, 22804419, 22804420, 20779109, 20779110 (and more).

Installation Support

This is a DIY-friendly repair that requires basic tools (Dremel, 1/4" socket) and a high-strength 24-hour epoxy (such as JB Weld 8265S).

Watch the Installation Video

Installation Snapshot:

Remove Seat: Gain access to the bottom seat structure.

Remove Old Plastic: Use a Dremel to carefully cut away the failed plastic spur gear.

gear experience

Posted by John B. Simms on 30th Jun 2021

2010 Buick Lucerne CXL - This gear worked like a charm! The instructional video was quite useful. I’m 99% noob and, with slow, deliberate work, even I was able to get this fixed.

Infinitely better than the plastic factory junk.

Posted by Frank Smoot on 18th Apr 2021

Great product! Though I would also have liked a bit of instructional material (exploded diagram, for example), the referenced video was very helpful. I would also add a few more details, having just installed them myself yesterday and today. But the gears themselves are excellent and worked perfectly. And this approach is WAY less expensive and better than any of the alternatives.

Great fix for a GM Shortcoming!

Posted by ERIC VREELAND on 10th Apr 2021

Thanks to Gruven for making this kit. There are a number of things GM could've done better with this design. Say metal gears with splines or keyway. I found it easiest to take out the whole seat and put in on sawhorses next to the truck with a clip on the seatbelt. The part about JB welding the gear on the shaft was a little scary. I was nervous about the .050 clearance at the tip but I used a spark plug gapping tool and it worked fine. The installation video I think says 5 thousandths for the tip gap but the calipers showed .050 which I think is 5 hundrdeths. Either way I went with .050 on my gapping tool and it went together well.

2011 Suburban seat issue solved with Gruven gear kit

Posted by Roger on 6th Apr 2021

i had just bought my 2011 Suburban and found the front seat would not move up or down on the front of the seat, all it would do it click, click, click when touch the switch. I knew a new or used seat bottom would be an expensive fix until i googled my problem and i found a video that talked about a problem Chevy had with 2007-2015 Suburban/Tahoe etc. and that's with i found Gruven Parts in Atlanta Ga area. So i ordered the kit and followed the video instructions and installed my kit and away we go!!! Happy Trails again!!!!! Thanks to Gruven for filling in the gap for Chevy! FIVE STARS from me!

A must for this repair...

Posted by Eddie Negron on 29th Jan 2021

Installation is relatively simple and straightforward. The installation kit should include a filler gauge type of measurement to set the main gear at .005". Overall great quality.

Challenging, but worth the effort GM folding Mirror fix, Seat lift gear.

Posted by Andrew A Thuernagle on 18th Jan 2021

The gear set is excellent. The video and instruction was also excellent with the step by step process. The first mirror took about two hours, the second took half hour. The seat lift gear took about 3 hours, It might be helpful for some to know that the seat tilt gear may also be upgraded with the same brass set while doing the project on some models. Thanks for everything.
