This PERRIN replacement rear sway bar bushing is made for 2008 and later Subaru WRX and STI models and is sized for the 22mm rear sway bar (replacement bushing only for PSP‑SUS‑232). Offered as a direct‑fit service part, the bushing restores proper sway bar mounting and reduces unwanted movement, preserving handling characteristics. It’s intended for owners replacing worn or damaged bushings without changing the sway bar itself.
