KYB 334473 Suspension Strut - Front Left

KYB Excel-G Front Left Strut for Toyota

The KYB Excel-G suspension strut is built to restore original ride control, steering response, and body stability on select Toyota applications. This part number 334473 is an OE-style replacement for the front left position on the Toyota Yaris and Toyota Prius C.

KYB’s Excel-G line is calibrated to return the vehicle to its designed handling balance rather than change the suspension feel. For Toyota Yaris and Prius C owners looking for a direct-fit front left strut, 334473 follows the OE approach used on KYB assembly lines.
