Smooth out a worn front corner and restore original ride height with the KYB Strut Plus SR4405, a complete strut and coil spring assembly that drops onto the front left corner of the 2006-2012 Toyota Avalon. As an original equipment supplier, KYB engineers this Strut-Plus unit to help restore the handling and control your Avalon was designed to deliver, pre-assembled so it installs as one ready-to-bolt corner.

  • KYB Excel-G strut: built with a stronger steel outer shell and KYB's application-specific precision-designed damping valves.
  • High-carbon steel coil spring: application-engineered to match the strut, help maintain proper ride height longer and control weight without sacrificing ride quality.
  • Side-specific design: left and right part numbers with side-specific components, as the vehicle manufacturer intended.
  • Electronic safety systems: engineered to help vehicles equipped with systems such as ESC and ABS.

Each KYB complete strut ships as a full corner unit — strut, mount and spring assembled together — for professional results. Named winner of the 2018 Best Overall Import Aftermarket Product, it is a direct-fit KYB front strut assembly for the listed Avalon application. See the Buyer's Guide tab to confirm your exact vehicle.
