KYB 235621 Suspension Strut - Rear

KYB Excel-G Rear Suspension Strut

The KYB Excel-G rear suspension strut is built to restore original ride control, stability, and steering response for select Ford and Mercury applications. This KYB Excel-G 235621 is a direct-fit OE-style replacement for rear suspension service on the Ford Contour, Mercury Mystique, and Mercury Cougar.

Excel-G is KYB’s OEA line, meaning it is calibrated to return the vehicle to its designed handling balance rather than alter it. For drivers replacing a worn rear strut on a Ford Contour or Mercury Mystique, KYB 235621 provides a vehicle-specific solution with OE-quality construction.
