06-13 Lexus IS250 RWD KYB Gas a Just Shocks Front+Rear

The KYB Gas-a-just monotube shock absorber has additional performance advantages over the traditional twin-tube design: It can instantly, automatically adjust to your performance needs and never experiences fade due to aeration. The Gas-a-just is available as an OE monotube replacement for vehicles that came equipped with a monotube shock, and as a performance upgrade on vehicles that came equipped from the factory with twin-tube shocks. 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.

The high pressure monotube design responds instantly to conditions and driver inputs to deliver increased handling capabilities over twin-tube designs.

Monotube shocks have separate chambers for the nitrogen gas and hydraulic fluid, this eliminates aeration and foaming and helps maintain consistent damping force in all conditions.

Fluid leaking can be a cause of shock failure, the KYB Gas-a-just has an ultra-smooth triple chrome plated chrome piston rod to reduce seal wear. The multi-lip, synthetic oil seal is engineered to keep fluid in and has a wiper to keep contaminants out of the oil.
