The Energy Suspension 17mm rear sway bar bushing set for 2002–2006 Subaru Impreza/WRX uses Hyper-Flex polyurethane to replace the factory bushings and improve sway bar effectiveness. These red rear bushings restore the sway bar's ability to control body roll, last longer than OEM rubber, and support more consistent handling; they are commonly installed during suspension refresh or when worn bushings cause looseness.
