Perrin Pitch Stop Mount Silver 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
Overview
The Perrin Pitch Stop Mount is a high-performance 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, Legacy 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 more rigid connection, controlling the front-to-back twisting forces generated by the drivetrain and improving power delivery to the wheels.
Engineered with precision from 6061 billet aluminum and featuring dual durometer bushings (90a and 70a), this mount balances stiffness with NVH (noise, vibration, harshness) control to enhance driving feel without introducing excessive vibration inside the cabin. Perrin’s design philosophy focuses on delivering durable, race-inspired components that maintain daily drivability while addressing the shortcomings of factory parts under increased power and torque loads.
For Subaru enthusiasts who have upgraded their engines or drivetrain components, the Perrin Pitch Stop Mount offers tangible benefits by minimizing drivetrain movement and shudder. This results in a more connected and responsive driving experience, improved throttle response, and more efficient power transfer, making it an essential upgrade for performance-oriented WRX, STI, Legacy, Impreza, Ascent, and Crosstrek owners.
