Description
GM Power Seat Forward/Aft Gear Repair Kit (Solid Brass)
Stop wasting money on entire power seat assemblies. Fix your GM vehicle’s forward/aft seat adjustment mechanism permanently with our precision-engineered Solid Brass gear set.
The power seat adjustment mechanisms in 2007–2014 GM vehicles commonly fail due to weak, brittle plastic gears. When these gears chip or strip, dealerships force you to purchase a complete new power seat unit—containing the exact same failure-prone plastic components. GruvenParts offers a superior, bulletproof alternative designed to last the life of your vehicle.

Installation Overview

- Gear Replacement: Open the gearbox and remove the old plastic gear from the spiral shaft (Dremel tool recommended).
- Bonding: Use a 24-hour epoxy (e.g., JB Weld 24-hour, not the 5-minute version) to bond the two halves of the brass gear onto the main spiral shaft.
- Reassembly: Reinstall components using the steel repair bushings to secure the frame rail.
