Subaru WRX Suspension Bushing Kit - Rear - COBB - Diff to Subframe Mount - 08-21. Upgrade the rear differential-to-subframe connection with COBB’s performance bushings for a tighter, more responsive driveline feel.

Engineered for enthusiasts who want cleaner power delivery and predictable handling, this kit limits differential movement under load. You’ll experience more consistent launches, improved traction, and reduced drivetrain lash, all in a direct-fit package. As with most performance bushings, expect a modest increase in NVH. Fitment includes 2008–2021 WRX and STI, 2018 Type RA, 2019 S209, and 2009–2013 Forester XT (FXT).
