KYB Shocks & Struts Gas-a-just Rear Left 2004 Subaru Impreza WRX STI

The KYB Gas-a-just monotube strut is built to bring your 2004 Subaru Impreza WRX STI back to its original handling capabilities. It features a monotube design with two distinct working chambers. One chamber houses an air-free hydraulic piston and valve system, which is key for responsive control. The second chamber contains a high-pressure nitrogen gas charge separated by a floating piston. This setup offers a comfortable ride during everyday driving but instantly adds performance when you need it, like during spirited driving or emergency maneuvers.

This design is important because modern electronic safety systems, such as ABS and stability control, rely on the suspension, brakes, and tires working together as the manufacturer intended. By restoring your vehicle's original suspension performance, the KYB Gas-a-just helps ensure these critical safety systems function correctly. This rear left strut is a well-built replacement designed to fit your Impreza WRX STI directly.
