Subaru WRX Bushing Kit - Rear - COBB - Pinion Crossmember Mount (2008–2021). This kit replaces the factory rear differential pinion crossmember bushings to firm up the driveline and sharpen response.

Engineered by COBB to curb movement at the rear differential, these bushings tighten the connection between the pinion mount and chassis. Less deflection helps cut driveline lash and wheel hop while improving consistency under throttle and during shifts. Direct-fit for 2008–2021 WRX; also listed by COBB for STI, 2018 Type RA, and 2009–2018 Forester XT. Professional installation recommended.

Features

• Replaces rear diff pinion crossmember mount bushings
