Help restore controlled, composed handling with the KYB Excel-G rear shock absorber (MPN 3440136), a nitrogen gas-charged, twin-tube damper built to bring back your vehicle's originally designed ride control. This KYB shock absorber installs as a direct-fit rear replacement for many vehicles, among them the 2019-2020 Hyundai Elantra, 2024-2026 Hyundai Kona and 2018-2022 Hyundai Ioniq — see the "Vehicles it fits" section for the full list and engine-level applications.
KYB classifies the Excel-G as OEA (Original Equipment for the Aftermarket): it is made on the same KYB OE assembly lines using the same OE-quality components, calibrated to restore original designed performance rather than change it.
- Nitrogen gas-charged twin-tube design: the #1 recommended Original Equipment replacement choice for Asian cars, designed to help restore the control and handling of your Hyundai or Kia.
- Triple-lip fluid seal: works to reduce 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.
- Supports electronic safety systems: helps keep them performing as the manufacturer intended by maintaining suspension behavior.
If a worn rear shock is the cause of excess body movement, bounce, or reduced handling, this shock absorber replaces it. Sold individually; replace rear shocks as a matched pair for balanced ride control.
