Add drive train rigidity and precision to your Subaru with our PERRIN Performance Diff Lock Down System.

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 road racing, drifting or drag racing this will handle and improve it all! Under these conditions the drivetrain (diff included) will twist and move causing a “squishy” or spongy feel at the point of initial acceleration. The PERRIN rear diff lock down (DLS) locks the differential down for zero movement.
