Key Features:

KYB’s Gas-A-Just shocks incorporate advanced technology and robust construction to ensure optimal performance and longevity. Key features include:

• High-Pressure Nitrogen Gas Design: The monotube design uses high-pressure nitrogen gas to eliminate aeration and foaming, resulting in consistent damping and quicker shock response.
• Increased Damping Force: Automatically adjusts to changing road conditions, delivering precise control and enhanced stability during cornering and rough terrain.
• Seamless Working Cylinder: Manufactured from a single piece of steel, this design reduces the risk of leaks and improves overall shock durability.
• Triple-Chrome Plated Piston Rod: Provides superior strength and corrosion resistance, extending the life of the shock.
• Heavy-Duty Construction: Built to withstand demanding driving conditions and heavy use, making it suitable for both performance and utility applications.
• Improved Ride Quality: Offers a firmer yet comfortable ride, reducing body roll and sway for better vehicle control.
• Long-Lasting Durability: Designed for extended service life with minimal maintenance.

Construction & Design:

The KG4159 shocks feature a robust monotube design that separates the gas and oil chambers with a floating piston, ensuring consistent damping performance without aeration. The seamless steel cylinder enhances structural integrity and prevents leaks, while the triple-chrome plating on the piston rod protects against corrosion and wear. This heavy-duty construction ensures the shocks can endure rigorous driving conditions, from daily commuting to aggressive cornering and towing.

KYB’s precision engineering guarantees that each shock delivers reliable performance and longevity, making the Gas-A-Just shocks a smart upgrade for Dodge Durango owners who demand both durability and improved handling.
