Rear Stabilizer Bar Kit

The Genuine Subaru 20451FE100 is a rear stabilizer, often referred to as a stabilizer bar or sway bar kit. Engineered as a direct replacement, this part is specifically designed to fit the 2004-2006 Subaru Impreza, Impreza WRX, and Impreza STI models with the 2.5L H4 Turbo engine. This genuine Subaru component is manufactured to meet strict quality standards, ensuring reliable performance and durability. The manufacturer note indicates STABILIZER(D=20), suggesting a 20mm diameter, which is a key specification for its function in managing body roll during cornering. While the stabilizer bar itself is provided, it's important to note that end links and bushings are not included and may need to be sourced separately. Installation typically involves raising the vehicle, removing wheels, and unbolting the old sway bar kit from the links and control arms. The process for replacing a sway bar kit and link on a Subaru Impreza is detailed in the provided repair tips, guiding users through loosening lug nuts, blocking wheels, and securing the vehicle on jackstands before proceeding with the removal and installation of the sway bar and associated bushings.
