The COBB rear diff pinion crossmember mount bushing kit for 2008–2021 Subaru WRX & STI (including 2018 Type RA and select FXT years) replaces worn mount bushings to restore proper rear diff-to-crossmember alignment. These bushings are supplied as vehicle-specific isolators to reduce diff movement, preserve drivetrain geometry and improve long-term mount performance compared with aged or deteriorated factory rubber.
