Product Details

KYB Excel-G shocks and struts are assembled on KYB OE production lines using OE-quality components and calibration focused on restoring designed suspension behavior rather than changing it. For rear suspension service on the Ford Taurus and Lincoln MKS, part number 3440037 is engineered to bring back controlled ride response, consistent handling, and proper suspension movement. This part cross-references Ford DG1Z18125E for the same application.

What This Shock Helps Address

• Excessive rear bounce after bumps
• Loose or unsettled handling in turns and lane changes
• Reduced braking stability caused by worn rear damping
• Uneven tire contact from weak suspension control
