Rear Shock Absorber for 2017-2022 Ford F-350 Super Duty & More - KYB 5540018

Control body motion and firm up the ride with the KYB shock absorber (Gas-a-just, MPN 5540018), a high-pressure monotube gas shock that installs as a direct-fit rear replacement for the 2017-2020 Ford F-250 Super Duty and 2017-2022 Ford F-350 Super Duty.

• Monotube gas design: 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 that separates gas and oil for fade-free operation and instant response.
• Triple chrome plated piston rod: an ultra-smooth rod that helps reduce seal wear, since fluid leaking can be a cause of shock failure.
• More damping on demand: higher gas pressure responds quickly to help improve steering response and adds up to 25% more damping performance over original equipment shocks.
• Built for the work: components and valving designed specifically for Super Duty Ford trucks, with additional damping over the OE design for vehicles that work, tow, and run larger, heavier tires and wheels.

The KYB Gas-a-just also helps keep Electronic Safety Systems performing as designed, since those systems depend on the suspension operating as the vehicle manufacturer intended. Sold individually; replacing both rear shocks together is recommended for balanced ride control.
