Product Details
The KYB Excel-G 343823 is engineered for drivers who want the suspension to perform like the original equipment setup. For the Toyota Yaris, this rear shock absorber is calibrated to restore ride control rather than change it, helping the vehicle maintain predictable stability and handling. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

For 2015-2018 Toyota Yaris rear applications, replace the suspension strut and coil spring assembly according to the manufacturer’s instructions. For 2014 Toyota Yaris rear applications, this is a recommended OEM replacement except for Japan-built vehicles.
Common Issues This Part Addresses
- Excessive bouncing after bumps or dips
- Reduced rear-end stability during braking or cornering

- Uneven ride control caused by worn rear shocks
- Loss of original suspension response on Toyota Yaris models
