This is a direct-fit replacement for the 2015-2021 Subaru WRX and 2015-2021 Subaru WRX STI [All engines], serving the rear lower forward position.

If a worn lateral arm or ball joint is behind clunking over bumps, loose rear-end handling, or uneven tire wear, this assembly replaces it. The listed applications use two per vehicle, so order two for a complete replacement. Country of origin: Turkey.
