About the KYB Gas-a-just Product Line

The Gas-a-just line from KYB focuses on gas-charged shock absorbers designed to provide consistent damping performance and improved vehicle control.

The KG5542 shock absorber benefits from this technology by delivering stable ride quality and responsive suspension behavior.

Detailed Product Description

The KYB Gas-a-just KG5542 suspension shock absorber features a compressed length of 16.38 inches and an extended length of 22.95 inches, providing a stroke length of 6.57 inches. This range allows for effective absorption of road irregularities while maintaining vehicle stability. The lower mount uses an E2 type (14.6x41), and the upper mount is an S1 type, ensuring proper fitment and secure installation on Porsche 911 models. The inclusion of a dust cover helps protect internal components from debris and extends the service life of the shock absorber. Additionally, the bump stop (B-stop) and rebound stop (R-stop) features help prevent over-compression and over-extension, protecting the suspension system during extreme driving conditions. This shock absorber does not include an internal rebound spring, which is consistent with the original equipment design for this application.
