Detailed Product Features and Specifications

This KYB Gas-a-just shock absorber (part number 555610) is designed with an internal rebound spring to provide consistent damping and improved control over road irregularities. The shock’s compressed length of 14.76 inches and extended length of 18.77 inches offer a stroke length of 4.01 inches, which is critical for maintaining suspension travel and vehicle stability.
