Product Details

KYB Excel-G is the brand’s OEA-style replacement line, meaning it is built to restore the vehicle’s original ride characteristics rather than alter them. For 1997-2002 Ford Expedition rear shock replacement, part number 344377 is engineered to match OE-style damping and support consistent suspension response in everyday driving, towing, and load-carrying conditions. This part cross-references Monroe Shocks & Struts (e.g., 37154) for the same application.

What This Shock Helps Address

• Excessive rear bounce after bumps or dips
• Reduced stability during lane changes and highway driving
• Longer stopping distances caused by worn rear damping
• Uneven tire contact from weak shock control
• Loose or unsettled rear suspension feel on a Ford Expedition
