KYB Suspension Shock Absorber P/N:554362

Description

Smooth out the ride and keep every heavy-duty mile controlled with the KYB shock absorber 554362, a High Pressure Monotube Gas (Gas-a-just) unit that drops in as a direct-fit rear replacement for the 2005-2016 Ford F-450 Super Duty and 2005-2016 Ford F-550 Super Duty. This high-pressure monotube design separates the gas and oil for fade-free operation and instant response, with components and valving designed specifically for heavy-duty trucks.

Monotube gas design: An air-free hydraulic piston/valve area handles responsiveness and control, while a separate high-pressure nitrogen chamber with a floating piston supports a comfortable ride and adds damping on demand — and never fades due to aeration.
Triple chrome-plated piston rod: An ultra-smooth rod reduces seal wear; since fluid leaking can be a cause of shock failure, this helps guard against it.
Built to tow and work: Adds up to 25% more damping over original-equipment shocks, with extra damping for trucks that work, tow, and run larger, heavier tires and wheels.
Steering and safety: Higher gas pressure responds quickly to improve steering response and helps keep electronic safety systems performing as designed.

Signs a rear shock may need replacing include excessive bounce, nose-dive, fluid seepage down the body, and poor control over bumps. Replace both sides as a matched pair for balanced ride control.

Frequently Asked Questions

What vehicles does KYB 554362 fit?

It is a direct-fit rear shock absorber for the 2005-2016 Ford F-450 Super Duty and 2005-2016 Ford F-550 Super Duty. See the "Vehicles it fits" section to confirm your exact configuration.

How is this KYB gas shock absorber different from a twin-tube?

This monotube Gas-a-just separates the gas and oil into distinct chambers, so it resists fade from aeration and responds instantly, unlike a traditional twin-tube design.

Does this shock help with towing and hauling?

Yes. Its components and valving are designed for heavy-duty trucks and add up to 25% more damping over OE shocks for vehicles that work, tow, and run larger, heavier tires and wheels.

Should I replace both rear shocks together?

Replacing both sides as a matched pair is recommended for even, balanced ride control, though each shock is sold individually and this listing is for one.

What are signs my rear shock needs replacing?

Excessive bounce, front-end nose-dive when braking, fluid seepage down the shock body, and poor control over bumps can indicate a worn shock. Diagnose the cause before replacing.
