The KYB Gas-a-Just monotube rear shock for 2017–2020 Ford F-250/2017–2022 F-350 4WD (excluding cab & chassis) offers responsive damping by separating an air-free hydraulic piston chamber from a high-pressure nitrogen gas chamber with a floating piston. That design resists fade, provides immediate control when demanded and still cushions normal driving, supporting electronic safety systems by helping the suspension perform as intended.
