Subaru WRX STI Bushing Kit - Rear - COBB - Pinion Crossmember Mount (2008–2021). Replaces the factory rear diff pinion crossmember bushings for a tighter, more controlled driveline.
Built by COBB Tuning for 2008–2021 Subaru WRX & STI, the 2018 Type RA, and 2009–2018 Forester XT, these bushings limit differential movement under load. Expect crisper throttle transitions, more consistent launches, and improved shift feel, with NVH typical of performance mounts.
Features
- Direct-replacement rear diff pinion crossmember bushings
- Helps reduce diff movement, wheel hop, and shudder
- Firmer, more connected shifts and throttle transitions
- Application: 2008–2021 WRX & STI; 2018 Type RA; 2009–2018 FXT
