PERRIN Differential Lockdown - Subaru Impreza/WRX (GDA/GGA) / STI (GDB) / Forester (SG9)
PERRIN builds this Differential Lockdown Kit to tighten up drivetrain slop and sharpen throttle response on your Subaru. By locking the rear differential more rigidly to the chassis, it reduces the flex that normally soaks up power delivery, giving you a more direct connection between throttle input and rear wheel response. SKU PSP-DRV-534.
This listing covers the Subaru Impreza and WRX (GDA/GGA), WRX STI (GDB), and Forester (SG9) built during the relevant production years. One kit fits all listed chassis using the shared rear differential mount design.
Key Features
- Reduces rear differential movement under load
- Improves drivetrain rigidity for more precise power delivery
- Bolt-in design using factory mounting points
- Complements other PERRIN drivetrain components
