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).

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

Perfect Solution

Posted by Jim on 7th Dec 2022

I purchased this part to replace the non-functioning factory gear on my 2007 Suburban 1500 LT. Driver seat would no longer adjust. The gear was a perfect fit and "easy" to install. A bit of a pain to get the seat out, etc., but that is GM not Gruven. Any way the seat now functions as it should.

Didn't know this part even existed

Went to the dealership they tried to sell me the whole bracket underneath the sheet for $600 So I got on the computer found the part Better than the original. --response-- Good. And the dealer knows about us, and could offer to sell just the gear but wont. Glad you found us and didnt reward the dealer for that sort of practice !

Top notch quality, best replacement for nylon/plastic GM gears. Fast shipping!

Posted by Rich on 10th Nov 2022

I've now bought 2 sets of these gears to fix the up/down motion of my 2012 Chevy Avalanche driver's seat. GM SHOULD have made them like this originally, but were apparently trying to save money and make as many of their parts out of plastic as possible--especially in the early to late 2000s. These gears are top notch quality. A huge upgrade that I won't have to worry about getting stripped out again. The shipping was super fast. Both sets were shipped within hours of ordering and showed up quickly. Thanks again!

Worked great and saved me a ton of money

Posted by Brandi H. on 7th Oct 2022

We purchased 2 sets of these gears for our 2012 Silverado. They worked well and our seat works great now. The dealer wanted $1,000+ to replace just the seat bottom. No thank you. We a bit of time you can save yourself a ton of money. I do wish there were written instructions with these gears though. Written and illustrated instructions would make a huge difference. Shipping is very fast and gears are well made.
