Smooth out the ride and keep body motion in check with the KYB Excel-G 2016-2018 Kia Optima shock absorber, MPN 3440143. This is a rear gas shock that installs as a direct-fit replacement for the 2016-2018 Kia Optima (see the Buyer's Guide tab for engine-level fitment). KYB calibrates the Excel-G to restore the vehicle's original, designed damping — an approach KYB calls OEA (Original Equipment for the Aftermarket).

  • Nitrogen gas-charged, twin-tube design: built on KYB's OE assembly lines with the same OE-quality components used in its global OEM shocks.
  • 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.
  • OEA calibration: designed to restore the original control and handling of the vehicle rather than change it, and to help keep electronic safety systems performing as intended.

Shocks wear gradually — signs this rear shock may need replacing include excessive bounce over bumps or reduced stability during lane changes. Replacing shocks in pairs across the axle is recommended for balanced ride control. Sold individually — this listing is for one shock.
