Help restore the designed ride control and handling of your Kia Optima with the KYB Excel-G Rear Shock Absorber, part number 3440143. It installs as a direct-fit rear replacement for the 2016-2018 Kia Optima — see the Buyer's Guide tab for engine-level fitment. Excel-G is a nitrogen gas-charged, twin-tube damper built on the same KYB OE assembly lines and calibrated to restore original, designed performance rather than change it, earning the OEA (Original Equipment for the Aftermarket) classification.

  • Nitrogen gas-charged twin-tube design: includes the same quality components KYB puts in its global OEM products.
  • Triple-lip fluid seal: helps 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: designed to help keep them performing as the vehicle manufacturer intended, since they depend on the suspension, brakes and tires working as designed.

KYB is a world-leading supplier of shocks and struts to new-vehicle manufacturers, and Excel-G is a preferred choice among professional technicians and a #1 recommended Original Equipment replacement for Asian cars. Sold individually; for even, balanced ride control, replacing both rear shocks as a matched pair is recommended.
