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 significant movement under hard driving conditions, creating drivetrain slop and shudder.
