Perrin Pitch Stop Mount Black 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 | Billet Aluminum | Drivetrain Mount
Overview
The Perrin Pitch Stop Mount is a 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 from various model years. This mount replaces the factory pitch stop, which is engineered primarily for light to moderate driving conditions and tends to allow excessive drivetrain movement during aggressive driving. The Perrin Pitch Stop Mount is aimed at Subaru enthusiasts who have upgraded their powertrain or seek a more direct and controlled driving experience.
Constructed from 6061 billet aluminum and featuring high-durometer bushings, this mount is engineered to provide a firmer connection between the engine and chassis without introducing excessive noise, vibration, or harshness (NVH). Perrin’s design philosophy balances stiffness and refinement, using 90a and 70a durometer bushings to minimize drivetrain slop while maintaining daily drivability. This approach ensures durability and precise control over drivetrain pitch, a critical factor for Subaru vehicles known for their all-wheel-drive torque dynamics.
By controlling the front-to-back twisting of the drivetrain caused by torque during acceleration, the Perrin Pitch Stop Mount improves throttle response and reduces drivetrain shudder. This translates to a more positive and connected feel behind the wheel, effectively transferring more power to the wheels by eliminating energy lost to drivetrain movement. For Subaru owners focused on performance and reliability, this mount is a practical upgrade that enhances both driving enjoyment and drivetrain longevity.
