Reduce drivetrain shudder under hard acceleration by installing a PERRIN Pitch Stop mount. Subaru's with power and drivetrain upgrades will need PERRIN's more aggressive option.

What does a pitch stop mount do?

Under hard acceleration, the drivetrain is being twisted front to back from front axle torque twist. To control this front to back twisting, Subaru created a pitch stop mount. The factory pitch stop is made of plastic with soft rubber bushings, allowing for a significant amount of movement under hard driving conditions, creating drivetrain slop and shudder.

Why Do I Need The PERRIN Pitch Stop Mount?

The PERRIN Pitch Stop mount controls the movement of the drivetrain in both on and off throttle driving giving the driver a more positive feel and literally putting more power to the wheels by eliminating lost energy.


The PERRIN Pitch Stop Mounts body is machined from 6061 billet aluminum and features a combination of 90a and 70a durometer bushings. The bushings are as stiff as possible without introducing excessive NVH. (noise vibration harshness)
