KYB Suspension Shock Absorber P/N:KG54319

$79.99

Description

Smooth out the ride and control powertrain-driven suspension motion with the KYB Gas-a-just Shock Absorber KG54319, a high-pressure monotube gas KYB shock absorber built as a REAR direct-fit replacement for the 1997-2002 Ford Expedition and the 1998-2002 Lincoln Navigator. Its components and valving are designed specifically for Ford and Lincoln SUVs, with added damping for vehicles that work, tow, and run larger, heavier tires and wheels.

Gas-a-just monotube 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 for a comfortable ride and instant performance on demand.
Up to 25% more damping: Adds up to 25% more damping performance over original equipment shocks.
Fade-free operation: The high-pressure monotube separates the gas and oil for fade-free operation and instant response, and never experiences fade due to aeration.
Triple chrome-plated rod: An ultra-smooth triple chrome plated piston rod helps reduce seal wear, a common cause of shock fluid leakage.

Higher gas pressure responds quickly to help improve steering response, and helps keep the vehicle's electronic safety systems performing as designed.

Frequently Asked Questions

What vehicles does the KYB KG54319 shock absorber fit?

It is a rear direct-fit replacement for the 1997-2002 Ford Expedition and the 1998-2002 Lincoln Navigator. See the Buyer's Guide tab to confirm your exact vehicle.

Is this a KYB gas shock absorber?

Yes. The KG54319 is a KYB Gas-a-just high-pressure monotube gas shock that separates gas and oil for fade-free operation and instant response.

What makes the monotube design different from a twin-tube shock?

It uses two separate chambers — an air-free hydraulic piston and valve area plus a high-pressure nitrogen gas area with a floating piston — which resists fade from aeration.

Does this shock add damping over the original equipment shocks?

KYB states the Gas-a-just adds up to 25% more damping performance over OE shocks, with extra damping for vehicles that work, tow, and run larger, heavier tires and wheels.

Should I replace shocks in pairs?

This listing is for one shock. Replacing both sides on the same axle together is recommended for balanced ride and handling. If worn shocks are the cause of your ride issues, this replaces one.
