Rear Shock Absorber for 2008-2016 Ford F-250 Super Duty & More - KYB 554388

Smooth out the ride and tame body motion with the KYB Gas-a-just Shock Absorber (P/N 554388), a high-pressure monotube gas KYB shock absorber built for the REAR of the 2008-2016 Ford F-250 Super Duty, 2008-2016 Ford F-350 Super Duty, and 2011-2016 Ford F-450 Super Duty. Its components and valving are designed specifically for Super Duty Ford trucks — see the "Vehicles it fits" section for the full engine-level fitment.

The Gas-a-just uses two separate 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 instant performance on demand.

• Monotube design: separates the gas and oil for fade-free operation and instant response, with no fade from aeration.
• Extra damping: adds up to 25% more damping performance over original equipment shocks — intended for trucks that work, tow, and run larger, heavier tires and wheels.
• Triple chrome plated piston rod: ultra-smooth rod helps reduce seal wear, since fluid leaking can be a cause of shock failure.
• Safety systems: helps keep Electronic Safety Systems performing as the vehicle manufacturer intended.

Sold individually; replacing both rear shocks together as a matched pair is recommended for balanced damping.
