Overview

The KYB Gas-a-Just Strut 551121 is a high-pressure monotube strut designed to enhance performance and handling. It features a high-pressure nitrogen gas design that eliminates aeration for consistent performance and quicker response times. The strut also offers increased damping force, automatically adjusting to changing road conditions for precise control and stability.
