Restore front ride height and factory-like handling with the KYB Strut-Plus Suspension Strut and Coil Spring Assembly (SR4125), a complete corner unit that drops in as a direct-fit replacement for the 2000-2005 Toyota Echo (front position). Pre-assembled with the strut, mount, and spring, it installs as a fully engineered unit for professional results — see the Buyer's Guide tab for engine-level details.

As an original equipment supplier, KYB builds this corner assembly around an OE-restoring strut so your vehicle can ride, handle, and perform close to how it did new.

  • KYB Excel-G strut: stronger steel outer shell with KYB's application-specific precision-designed damping valves.
  • High-carbon steel coil spring: developed considering vehicle attributes and corner weights to help keep ride height within OE specifications.
  • Application-engineered spring: matched to the strut to help maintain proper ride height longer and control weight without sacrificing ride quality.
  • Safety-system aware: engineered to help vehicles equipped with electronic safety systems (ESC, ABS, etc.).

A strut assembly supports vehicle weight, sets ride height, and serves as the steering pivot while helping control stability. Winner of Best Overall Import Aftermarket Product and a #1 recommended OE replacement choice for Asian vehicles.
