Subaru WRX/STI Differential Lockdown Kit by Perrin Performance

Add drivetrain rigidity and precision to throttle input to your Subaru with our PERRIN Differential Lockdown Kit.

The PERRIN Differential Lockdown kit consists of 2 aluminum plates and 4 urethane bushings to completely remove any and all movement from the rear differential under all conditions. From performance street driving, to track racing, drifting or drag racing, this will handle and improve it all! Under these conditions the OEM drivetrain (differential included) will twist and move causing a "squishy" or spongy feel at the point of initial acceleration. The PERRIN Rear Differential Lockdown (DLS) locks the differential down for zero movement.
