Settle the ride and help restore factory-designed control with the KYB Excel-G Suspension Shock Absorber 343823, a rear-position, nitrogen gas-charged, twin-tube damper that drops in as a direct-fit replacement for the 2014-2018 Toyota Yaris. Built on the same KYB assembly lines that supply new-vehicle manufacturers, the Excel-G uses OE-quality components and is calibrated to return original, designed performance rather than change it — the reason KYB classifies it as OEA (Original Equipment for the Aftermarket).
- Twin-tube, gas-charged design: nitrogen gas-charged construction that includes the quality components found in KYB's global OEM products.
- Triple-lip fluid seal: reduces the chance of oil and gas leaking out.
- Vehicle-specific damping valves: hand-assembled in-house to manage tire contact, steering response, and body movement.
- Strong body and brackets: thick bodies and brackets that minimize flex to help maintain correct alignment.
The Excel-G helps restore the designed control and handling of your Yaris and helps keep electronic safety systems performing as the manufacturer intended. Worn shocks may show up as excessive bounce, nose dive under braking, or reduced stability during lane changes — if the rear shock is the cause, this replaces it.
