Bring back front-right ride height and controlled handling on your 2009-2013 Mazda 6 with the KYB Strut-Plus Suspension Strut and Coil Spring Assembly (SR4558). This complete corner unit ships pre-assembled with the strut, mount and spring, so it drops into the front right position as an application-engineered replacement.
