KYB Gas-a-Just Front Left Monotube Strut for Lexus IS250 and IS350

The Gas-a-just monotube strut is available as an OE monotube replacement to restore your vehicle's original capabilities. The KYB Gas-a-just has two separate working chambers: An air-free hydraulic piston and valve area for responsiveness and control, and a second high-pressure nitrogen gas area with a floating piston that provides a comfortable ride during normal driving and adds instant performance on demand.

• Electronic safety systems depend on the suspension, brakes and tires operating as the vehicle manufacturer intended. The KYB Gas-a-just helps keep Electronic Safety Systems performing as designed.

Restore responsive handling and original suspension performance with the KYB Gas-a-Just front left monotube strut. Designed as an OE-style replacement, this KYB strut helps support the vehicle’s intended ride control, stability, and braking performance without requiring modifications to the factory suspension system.

The KYB Gas-a-Just uses a twin-chamber monotube design with an air-free hydraulic piston and valve area for precise response and control.

This design helps the suspension react quickly to changes in road surface and vehicle movement.
