Help restore the designed control and handling of your Hyundai or Kia with the KYB Excel-G Rear Shock Absorber (MPN 3440158). It drops in as a direct-fit rear replacement for the 2017-2018 Hyundai Elantra, 2018 Hyundai Elantra GT, 2019-2021 Hyundai Veloster, 2020-2024 Kia Forte, and 2018-2022 Kia Niro — see the Buyer's Guide tab for engine-level fitment. KYB is a world-leading supplier of shocks and struts to new-vehicle manufacturers, and the Excel-G is built on the same OE assembly lines with the same OE-quality components, calibrated to restore original designed performance rather than change it — earning it the OEA (Original Equipment for the Aftermarket) classification.

  • Nitrogen gas-charged twin-tube design: the Excel-G includes every quality component found in KYB's global OEM products and is the preferred choice of professional technicians.
  • Triple-lip fluid seal: reduces the chance of oil and gas leaking out.
  • Vehicle-specific, hand-assembled damping valves: designed to correctly manage tire contact, steering response, and body movement.
  • Supports electronic safety systems: helps keep suspension, brakes, and tires operating as the vehicle manufacturer intended.

Worn rear shocks can show up as excessive bouncing, reduced stability, and poor ride control; if the original rear shock is the cause, this replaces it. Replace shocks in axle pairs for balanced ride control.

Frequently Asked Questions

What vehicles does this KYB shock fit?

It's a rear-position fit for the 2017-2018 Hyundai Elantra, 2018 Hyundai Elantra GT, 2019-2021 Hyundai Veloster, 2020-2024 Kia Forte, and 2018-2022 Kia Niro. Check the Buyer's Guide tab for engine-level fitment.

Is this a gas shock?

Yes. The KYB Excel-G is a nitrogen gas-charged, twin-tube design that includes the same quality components used in KYB's global OEM products.

What does the OEA classification mean?

OEA stands for Original Equipment for the Aftermarket. The Excel-G is made on the same KYB OE assembly lines and calibrated to restore original designed performance, not change it.

How does the triple-lip seal help?

The triple-lip fluid seal is designed to reduce the chance of oil and gas leaking out of the shock, helping it maintain consistent damping.

Should I replace both rear shocks together?

Replacing shocks in axle pairs is recommended for balanced, even ride control. If a worn rear shock is the cause of bouncing or reduced stability, this unit replaces it.
