Description
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.

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).
