Detailed Description

Gas-a-just is KYB’s monotube shock line, and this 5550005 rear shock uses an air-free hydraulic working area paired with a high-pressure nitrogen chamber and floating piston. That layout improves steering response, keeps damping consistent under load, and helps the Ford Escape maintain the control and handling characteristics it was designed with. This part cross-references Monroe Shocks & Struts 39111 for the same application.
