The KYB Gas-a-Just rear shock for 2011–2022 Dodge Durango and 2011–2021 Jeep Grand Cherokee is a monotube design that offers instant, automatic damping adjustment and resists fade from aeration. It uses separate working chambers—a hydraulic piston and valve area plus a high-pressure nitrogen gas chamber with a floating piston—providing responsive control and a comfortable ride across conditions.
