Perrin Pitch Stop Mount Blue 2002-2024 WRX / 2004-2021 STI / 2005-2009 Legacy GT/ 2020-2024 Legacy XT / 1993-2024 Impreza / 2019-2024 Ascent / 2013-2024 Ascent / 2013-2024 Crosstrek | 6061 Billet Aluminum | Drivetrain Mount Upgrade
Overview
The Perrin Pitch Stop Mount is a precision-engineered drivetrain component designed to reduce engine and transmission movement under hard acceleration for a wide range of Subaru models including WRX, WRX STI, Legacy GT/XT, Impreza, Ascent, and Crosstrek. This mount replaces the factory pitch stop, which is made from plastic and soft rubber bushings that allow excessive drivetrain slop and shudder during aggressive driving. The Perrin Pitch Stop Mount provides a firmer, more controlled connection between the drivetrain and chassis, improving throttle response and power delivery.
Built with a focus on durability and performance, this mount features 6061 billet aluminum construction paired with dual durometer bushings (90a and 70a) that strike a balance between stiffness and NVH (noise, vibration, harshness) control. Perrin’s design philosophy centers on enhancing drivetrain control without introducing excessive vibration or harshness, making it an ideal upgrade for Subaru enthusiasts who have modified their powertrain or demand sharper throttle feedback.
By minimizing drivetrain movement front-to-back, the Perrin Pitch Stop Mount helps eliminate lost energy caused by torque twist, effectively putting more power to the wheels. This upgrade is especially beneficial for Subaru owners with power and drivetrain enhancements, delivering a more positive and connected driving experience both on and off throttle. It’s a practical and reliable solution to improve drivetrain engagement and overall vehicle responsiveness.
