The KYB Gas-a-just monotube strut is a direct-quality replacement that restores original ride control for Lexus IS250 and IS350 models (2006–2012). It uses two working chambers—a hydraulic piston and a high-pressure nitrogen chamber with a floating piston—to balance daily comfort with responsive control when conditions demand it. Replace worn strut mounts when servicing to reduce noise and vibration; KYB recommends part SM5642 for best results.
