Cobb 08-21 Subaru WRX & STI/2018 Type RA/09-18 FXT Rear Diff Pinion Crossmember Mount Bushings
These Cobb Rear Diff Pinion Crossmember Mount Bushings replace worn factory rubber mounts on 2008-2021 Subaru WRX and STI models, including the 2018 Type RA, plus 2009-2018 Forester XT.

Drivers experience crisper shifts, reduced wheel hop, and enhanced traction during hard acceleration and cornering.
