These QiMox hood lift supports are a direct-fit replacement for Lexus RX350 and RX450H (2016–2022), restoring steady, smooth hood opening and secure hold with OEM-style fit and durable hydraulic performance.

• Eliminates hood sag and reduces risk of slamming
• Extended 19.92" and compressed 11.61" stroke fits OEM geometry
