Rear Stabilizer Bar

The Genuine Subaru Stabilizer-Rear D20 (part number 20451VA000) is a direct replacement rear stabilizer bar, also commonly referred to as a rear sway bar. This genuine Subaru part is produced to provide reliable performance and durability. The stabilizer bar is backed by Subaru's factory warranty and manufacturer certification, with a 12-month/12,000-mile warranty also mentioned. This rear stabilizer bar is confirmed to fit the 2015-2019 Subaru WRX and 2015-2019 Subaru WRX STI models, including trims like Base, Limited, Premium, and S209 with 2.0L H4 and 2.5L H4 Turbo engines. Some sources also indicate fitment for the 2013-2017 XV Crosstrek and potentially the 2019 Outback, though primary fitment focuses on WRX and WRX STI models. Installation is reported to be straightforward and can be completed relatively quickly, sometimes in under 20 minutes with basic tools.
