Perrin Pitch Stop Mount

Reduce drivetrain shudder under hard acceleration by installing a PERRIN Pitch Stop Mount. Subarus 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 the 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 You Need It?

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.

Construction

The PERRIN Pitch Stop Mount's body is machined from 6061 billet aluminum and features a combination of 95a front and 70a rear durometer bushings. The bushings are as stiff as possible without introducing excessive NVH (noise, vibration & harshness).
