Product Description

The PERRIN PSP-SUS-235 rear endlinks use precision spherical bearings to eliminate unwanted flex in the rear sway-bar linkage of Subaru WRX and WRX STI models. OEM links often include rubber bushings that allow movement under load, reducing sway-bar efficiency. These performance links provide a solid connection for improved handling and more direct driver feedback, especially when paired with upgraded sway bars or lowered suspensions.

Designed with adjustable length, the endlinks accommodate modifications in ride height and maintain proper sway-bar geometry. Installation is straightforward, using the included hardware and spacers. Note that spherical bearings can increase noise and vibration compared to OEM rubber bushings - this is normal and expected for performance applications.

Fitment is confirmed through 2023 for WRX and 2021 for WRX STI. Compatibility with 2024-25 models is unconfirmed at this time. Ideal for performance enthusiasts seeking better cornering stability and enhanced chassis response.
