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. Crafted from high-durometer polyurethane, they eliminate pinion gear movement under load for direct power delivery to the wheels. Drivers experience crisper shifts, reduced wheel hop, and enhanced traction during hard acceleration and cornering.
