KYB Suspension Strut and Coil Spring Assembly P/N:SR4555
Help restore rear ride height and original handling with this KYB strut assembly, the KYB Strut-Plus Suspension Strut and Coil Spring Assembly, part number SR4037. This complete strut and coil spring assembly (one corner's strut, mount, and spring) installs as a rear replacement on many vehicles, among them the 1998-2003 Chevrolet Malibu, 2004-2005 Chevrolet Classic, and 1999-2005 Pontiac Grand Am; see the Buyer's Guide tab for the full list.
Part of the KYB complete struts line, this KYB strut plus assembly arrives pre-assembled for exact fitment and professional results. As an original equipment supplier, KYB builds it on an OE-restoring Excel-G strut, so it's engineered to help restore your GM car's handling and control.
If a worn rear strut is the cause of a bouncy ride, sagging ride height, or reduced control, this KYB quick strut assembly replaces it. It is sold individually; replacing both rear corners together as a matched pair is recommended for balanced ride and handling.
