Keep your Lexus planted and responsive with the KYB Gas-a-just Suspension Strut 551130, a high-pressure monotube gas strut that installs at the front right corner. It's a direct-fit replacement for the 2016 Lexus IS200T, 2006-2015 Lexus IS250, and 2006-2016 Lexus IS350 — designed to help restore the vehicle's original control and handling.
- Twin working chambers: an air-free hydraulic piston and valve area for responsiveness and control, plus a high-pressure nitrogen gas area with a floating piston for a comfortable ride during normal driving and added performance on demand.
- High-pressure monotube design: separates the gas and oil for fade-free operation and instant response.
- Triple chrome-plated piston rod: ultra-smooth finish to reduce seal wear, since fluid leaking can be a cause of shock failure.
- Built to work: designed for vehicles that work, tow, and run larger, heavier tires and wheels.
The higher gas pressure responds quickly to help improve steering response, and KYB notes the Gas-a-just helps keep Electronic Safety Systems performing as designed. To reduce the chance of noise and vibration, KYB recommends installing new strut mounts (part number SM5642). Sold individually as the front right unit; replacing the opposite front strut at the same time is recommended for balanced handling.
