Add drivetrain rigidity and precision to throttle input to your Subaru with our PERRIN Differential Lockdown Kit.
The PERRIN Differential Lockdown Kit reduces movement from the rear differential under most conditions. From the street to the track, this will handle it all! Under tough driving conditions, the drivetrain, differential included, will twist. This movement causes a "squishy" or “spongy” feel at the point of initial acceleration. The PERRIN Rear Differential Lockdown locks the differential down for significantly reduced movement and better driver feel.
