Keep the rear of your Ford EcoSport planted and controlled with the KYB Gas-a-just Suspension Shock Absorber (MPN 5530020), a high-pressure monotube gas shock that drops in as a direct-fit rear replacement for the 2018-2021 Ford EcoSport. Its components and valving are designed specifically for the EcoSport, and it's offered as an OE monotube replacement to help restore your vehicle's original ride and handling.
- Two 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 added performance on demand.
- High-pressure monotube design: separates the gas and oil for fade-free operation and instant response, adding up to 25% more damping over a twin-tube shock — useful for vehicles that work, tow, or run larger, heavier tires and wheels.
- Triple chrome-plated piston rod: an ultra-smooth finish that helps reduce seal wear, since fluid leakage can be a cause of shock failure.
- Higher gas pressure is designed to respond quickly for improved steering response and helps keep Electronic Safety Systems performing as intended.
Shocks wear as a pair, so replacing both rear units together is recommended for balanced damping. Sold individually.
