KYB Suspension Shock Absorber P/N:554402

$110.99

Description

Firm up rear ride control and keep the 2012-2018 Ford Focus planted with the KYB Gas-a-just Suspension Shock Absorber 554402, a high-pressure monotube gas shock built as a rear-position replacement with components and valving designed specifically for the Ford Focus. See the Buyer's Guide tab for full engine details.

The Gas-a-just monotube separates the gas and oil into two working chambers: an air-free hydraulic piston and valve area for responsiveness and control, and a high-pressure nitrogen gas area with a floating piston for a comfortable ride during normal driving.

Fade-free operation: the high-pressure monotube design keeps gas and oil separated, so it resists fade from aeration and responds instantly.
Extra damping: adds additional damping over OE design for vehicles that work, tow, and run larger, heavier tires and wheels — up to 25% more damping performance versus original-equipment shocks.
Reduced seal wear: an ultra-smooth triple chrome-plated piston rod helps reduce seal wear, since fluid leaking can cause shock failure.
Quicker response: higher gas pressure helps improve steering response and supports the electronic safety systems that depend on the suspension.

Frequently Asked Questions

What vehicle does this shock fit?

It is a direct-fit replacement for the 2012-2018 Ford Focus, with components and valving designed specifically for that application. See the Buyer's Guide tab to confirm your vehicle.

What position does the 554402 install in?

This KYB Gas-a-just shock is cataloged for the rear position on the listed Ford Focus applications.

What makes a monotube gas shock different?

The high-pressure monotube design separates the gas and oil into two chambers, which resists fade from aeration and helps deliver instant, consistent response.

Does it offer more damping than the stock shock?

Yes. KYB states the Gas-a-just adds additional damping over the OE design — up to 25% more damping performance versus original-equipment shocks.

Should I replace both rear shocks together?

Shocks are sold individually. Replacing both sides on the axle as a matched pair is recommended for balanced, even ride control.
