Perrin Street Series Pitch Stop Mount Neon Yellow 2002-2026 WRX / 2004-2021 STI / 2005-2009 Legacy GT / 2020-2024 Legacy XT / 1993-2024 Impreza / 2019-2024 Ascent / 2013-2024 Crosstrek | Polyurethane Bushings | Drivetrain Mount
Overview
The Perrin Street Series Pitch Stop Mount is a precision-engineered drivetrain component designed to reduce drivetrain shudder and control movement under hard acceleration for a broad range of Subaru models including WRX, WRX STI, Legacy, Impreza, Ascent, and Crosstrek. This mount replaces the OEM rubber pitch stop with a durable polyurethane bushing setup that offers increased stiffness without compromising daily driving comfort. It is ideal for Subaru enthusiasts seeking improved throttle response and drivetrain feel without the harshness associated with race-oriented mounts.
Constructed from CNC-machined 6061-T6 aluminum and finished with a corrosion-resistant anodize coating, the Street Series Pitch Stop Mount balances performance and longevity. The design philosophy focuses on delivering a noticeable reduction in drivetrain slop while maintaining low noise, vibration, and harshness (NVH) levels suitable for street use. Perrin’s approach ensures that the mount outlasts OEM rubber components, which degrade over time and lead to drivetrain looseness and shudder.
By controlling the front-to-back twist of the drivetrain caused by torque during acceleration, this mount improves power transfer to the wheels and enhances overall driving engagement. For Subaru owners, this means a more connected feel behind the wheel with reduced drivetrain movement, making it a practical upgrade for daily drivers who want a sharper and more responsive driving experience without sacrificing comfort.
