Product Line Details

KYB Excel-G is engineered as an original-equipment-style replacement line for drivers who want the suspension to perform as the vehicle manufacturer intended.

What It Helps Address

• Excessive rear-end bounce or oscillation
• Loose or unstable handling over uneven pavement
• Reduced braking stability caused by worn suspension damping
• Delayed response during lane changes and cornering
