Bring back factory ride height and control on your 2011 Hyundai Sonata with the KYB Strut Plus SR4640, a complete strut and coil spring assembly for the front right corner. This pre-assembled corner unit combines a KYB Excel-G strut, its matched upper mount, and an application-engineered coil spring, so you install one bolt-in unit instead of building the assembly from separate parts.
OE-restoring design: Built on an Original Equipment Restoring KYB strut with a stronger steel outer shell and KYB's application-specific precision-designed damping valves, engineered to help restore the handling and control your Sonata had when new.
High carbon steel coil spring: The application-engineered spring is developed considering vehicle attributes and corner weights to help keep ride height within OE specifications while controlling weight without sacrificing ride quality.
Safety-system aware: A strut assembly supports vehicle weight, sets ride height, and acts as a steering pivot; this unit is engineered to help vehicles equipped with electronic safety systems such as ESC and ABS.
KYB is the #1 recommended Original Equipment replacement choice for Asian vehicles and winner of Best Overall Import Aftermarket Product. Assembled in USA.
Fits: 2011 Hyundai Sonata (front right).
