Detailed Description

This Stabilus gas spring is engineered around the listed dimensions and connection style to match the original support geometry used on select Kia hatchback and EV liftgate applications. The 4B-378125 cross-references Carlson 7174 and Tuff Support 612656 for the same application. It fits 2014-2019 Kia Soul and 2015-2019 Kia Soul EV, making it a direct-fit option for owners searching for a Kia Soul liftgate gas strut or Kia Soul EV hatch support by part number 4B-378125.

What It Helps Address

  • Weak or failing liftgate support
  • Hatch that drops instead of staying open
  • Uneven or inconsistent opening effort
  • Noisy or worn gas strut operation
  • Replacement needs after loss of gas pressure

Installation Notes and Tips

Verify the compressed length, extended length, force rating, and plastic socket attachment style before installation. Compare the existing support to the new Stabilus 4B-378125 to confirm the rod and tube connection points match the vehicle. For best results, replace only with the correct application listed for your Kia Soul or Kia Soul EV and inspect the mounting sockets for wear before snapping the new strut into place.
