Product Details

KYB Excel-G is KYB’s OE-style replacement line for drivers who want the suspension to perform as the vehicle was originally engineered. This strut uses the same type of quality control and component standards found in KYB original equipment production, making it a practical choice for restoring the front suspension on a Honda Civic.
