Product Details

KYB designed the Strut-Plus line to restore the handling and control characteristics expected from the original suspension. The SR4002 combines a KYB Excel-G strut, precision damping calibration, and a vehicle-specific coil spring to help return the front suspension to OE specifications. This part cross-references Monroe Shocks & Struts (e.g., 171661) for the same application. It is a strong service option for drivers looking for a front strut assembly for 1997-2005 Buick Century, 1997-2004 Buick Regal, 2000-2003 Chevrolet Monte Carlo, 2000-2005 Chevrolet Impala, and 1997-2003 Pontiac Grand Prix applications.
