Product Details

KYB Excel-G struts are built on KYB OE assembly lines using OE-quality components and are classified as Original Equipment for the Aftermarket. The 334640 is engineered to restore the suspension performance the Ford Five Hundred and Mercury Montego were designed to deliver, which is important for ride control, lane-change responsiveness, braking stability, and overall handling. This part cross-references Monroe Shocks & Struts 72255 for the same application.

Part number 334640 is a practical choice when replacing a worn front right suspension strut on these vehicles. It is designed to work with the vehicle’s suspension, brakes, and electronic safety systems as originally intended by the manufacturer.

Common Problems This Strut Can Address

• Excessive bouncing or poor damping over bumps
• Loose or delayed steering response
• Nose dive during braking
• Body roll or instability in turns and lane changes
• Uneven tire contact caused by worn suspension control

Installation Notes

Install on the front right position only for the listed applications. Replace the suspension strut and coil spring assembly according to the manufacturer’s instructions. Verify all mounting dimensions before installation, including compressed length, extended length, stroke length, and upper mount type. After installation, perform a professional alignment to confirm correct suspension geometry.

Quality Assurance

KYB supplies shocks and struts to new vehicle manufacturers, and the Excel-G line is produced using OE-style components and calibration standards to restore original performance. The strut body and bracket design is built to reduce flex and help maintain alignment under driving load.
