Perrin Pitch Stop Mount Red 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 designed to reduce drivetrain shudder and improve power delivery under hard acceleration for a wide range of Subaru models including WRX, STI, Legacy GT/XT, Impreza, Ascent, and Crosstrek. This component replaces the factory pitch stop mount, which is engineered primarily for light to moderate driving conditions and features softer bushings that allow excessive drivetrain movement. Enthusiasts with power upgrades or those seeking a more connected driving experience will benefit from Perrin’s stiffer, more durable solution.
Constructed from 6061 billet aluminum and paired with dual durometer bushings (90a and 70a), the Perrin Pitch Stop Mount is engineered to control engine and transmission pitch more effectively without introducing excessive noise, vibration, or harshness (NVH). This balance of stiffness and refinement reflects Perrin’s commitment to performance and daily drivability, making it a standout choice for Subaru owners who demand both reliability and enhanced drivetrain engagement.
By minimizing the front-to-back twisting of the drivetrain caused by torque during aggressive acceleration, this mount reduces drivetrain slop and shudder. The result is a more positive throttle response and improved power transfer to the wheels, which is especially noticeable in modified Subarus with increased torque output. This upgrade enhances the overall driving experience by delivering a firmer, more controlled feel while maintaining comfort for street use.
