Warranty & Instructions
Add drivetrain rigidity and precision to throttle input to your Subaru with the Perrin Differential Lock Down Kit. The Perrin DLS kit consists of 2 aluminum bushings and 4 urethane bushings to completely remove any movement from the rear differential under extreme conditions such as drag racing and road racing. During all out driving conditions the drivetrain (diff included) will twist and move around before it starts to turn the wheels making initial acceleration very numb. The Perrin DLS locks the differential down for zero movement so when you push on the gas squatting is reduced and any delay in power transmission between the engine and wheels is eliminated.
Usually ships within 4 days.
