Bring stable, controlled damping back to the rear axle with the KYB shock absorber, part number 3440061. This rear gas shock drops in as a direct-fit replacement for the 2015-2019 Hyundai Sonata, 2016-2020 Kia Optima and 2017-2020 Kia Cadenza, and it's built to the KYB Excel-G specification — a nitrogen gas-charged design calibrated to restore the vehicle's original ride control, stability and handling rather than change it.

  • Nitrogen gas-charged, twin-tube design: the KYB Excel-G shock absorber includes the same quality components KYB uses in its global OEM products.
  • Triple lip fluid seal: designed to reduce the chance of oil and gas leaking out.
  • Vehicle-specific, hand-assembled damping valves: tuned to manage tire contact, steering response and body movement.
  • OEA (Original Equipment for the Aftermarket): helps keep Electronic Safety Systems performing as designed and is the #1 recommended Original Equipment replacement choice for Asian cars.

Made on the same KYB OE assembly lines, this KYB gas shock absorber excel g helps restore the designed control and handling of your Hyundai Sonata or Kia Optima. Sold individually; replacing both rear shocks as a matched pair is recommended for even, balanced ride control.
