Reduce drivetrain shudder under hard acceleration by installing a PERRIN Pitch Stop mount. The factory pitch stop mount is designed to control the pitching of the engine and transmission under light to normal acceleration. Subaru's with power and drivetrain upgrades will need PERRIN's more aggressive option.
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 & shudder.
