Description:

Get the KYB KG5421 Shock Absorber for your vehicle. Buy now and secure your purchase online!

The KYB Gas-a-just monotube shock absorber has additional performance advantages over the traditional twin-tube design: It can instantly, automatically adjust to your performance needs and never experiences fade due to aeration. The KYB Gas-a-just has two separate working chambers: An air-free hydraulic piston and valve area for responsiveness and control, and a second high-pressure nitrogen gas area with a floating piston that provides a comfortable ride during normal driving and adds instant performance on demand.

Features and Benefits:

Adds up to 25% more damping performance over original equipment shocks
Components and valving designed specifically for Ford trucks
Electronic safety systems depend on the suspension, brakes and tires operating as the vehicle manufacturer intended. The KYB Gas-a-just helps keep Electronic Safety Systems performing as designed.
Fluid leaking can be a cause of shock failure, the KYB Gas-a-just has an ultra-smooth triple chrome plated chrome piston rod to reduce seal wear
Gas-a-Just monotubes include additional damping over OE design for vehicles that work, tow, and have larger, heavier tires & wheels
High pressure monotube design separates the gas and oil for fade free operation and instant response
The higher gas pressure of the KYB Gas-a-Just responds quickly to improve steering response
