The KYB Gas-a-Just monotube front strut for Lexus IS250/IS350 (2006–2012) restores OE-style responsiveness with a two-chamber design: an oil chamber for control and a high-pressure nitrogen gas chamber with a floating piston for comfort and instant performance on demand. This direct-replacement strut targets balanced ride quality and handling. KYB also recommends replacing strut mounts (part SM5642) to reduce noise and vibration during installation.
