Smooth out a worn rear ride and bring back the damping your suspension was built for with the KYB Excel-G Rear Shock Absorber 3440114. It installs as a direct-fit rear replacement for the 2018-2023 Hyundai Kona and 2019-2022 Kia Niro EV — see the Buyer's Guide tab for the full engine-level fitment. KYB's Excel-G is a nitrogen gas-charged, twin-tube design classified as OEA (Original Equipment for the Aftermarket), calibrated to restore the vehicle's originally designed control and handling rather than change it.
- Twin-tube, gas-charged: a nitrogen gas-charged, twin-tube build that includes the same quality components found in KYB's global OEM products.
- Triple-lip fluid seal: helps reduce the chance of oil and gas leaking out.
- Vehicle-specific valving: hand-assembled, application-specific damping valves manage tire contact, steering response and body movement.
- Supports safety systems: designed to help keep electronic safety systems performing as intended, since they depend on the suspension operating as designed.
If your rear shocks are worn, this is an OE-quality replacement designed to restore the vehicle's original ride control, stability and handling. Sold individually; replace rear shocks as a pair for balanced damping.
