KYB Suspension Shock Absorber P/N:554145

Firm up the back of your minivan with the KYB shock absorber 554145, a high-pressure monotube gas unit that installs as a direct-fit rear replacement for the 2002-2005 Kia Sedona, with components and valving designed specifically for that application.

• High-pressure monotube design: separates the gas and oil into two working chambers for fade-free operation and instant response.
• Gas-a-just chambers: an air-free hydraulic piston and valve area for responsiveness and control, plus a high-pressure nitrogen area with a floating piston for a comfortable ride and added performance on demand.
• Triple chrome-plated piston rod: an ultra-smooth surface helps reduce seal wear, since fluid leaking can be a cause of shock failure.
• Extra damping over OE: adds up to 25% more damping than original-equipment shocks for vehicles that work, tow, and run larger, heavier tires and wheels.

The higher gas pressure is designed to respond quickly for improved steering response, and KYB notes the Gas-a-just helps keep electronic safety systems performing as designed, since those systems depend on the suspension, brakes, and tires operating as the vehicle manufacturer intended. Sold individually as a rear shock; replacing both sides as a matched pair is recommended for balanced ride control.
