Cobb 08-21 Subaru WRX & STI/2018 Type RA/2019 S209/09-13 FXT Rear Diff to Subframe Mount Bushing Kit
This Cobb bushing kit replaces worn OEM rubber mounts with high-durometer polyurethane for 2008-2021 Subaru WRX/STI models, including 2018 Type RA, 2019 S209, and 2009-2013 Forester XT. It eliminates rear differential movement against the subframe, delivering direct power transfer and reduced wheel hop.

- Made in USA: Precision CNC-machined components built to Subaru tolerances for long-term durability under high-performance use.
