Description

The PERRIN Rear Differential Lockdown Kit (PSP-DRV-534) is designed to reduce unwanted rear differential movement in early Subaru platforms. From the factory, soft rubber bushings allow the rear differential to shift under throttle, causing delayed power delivery and inconsistent drivetrain response. By locking down the rear differential, this kit improves throttle response, drivetrain precision, and overall driving feel.
