Raise your KIA Soul's rear glass with a smooth, controlled motion using the Stabilus Liftgate Lift Support 4B-378125, a gas-charged lift support with dynamic speed control. It installs as a direct-fit replacement for the 2014-2019 KIA Soul and the 2015-2019 KIA Soul EV, holding the liftgate open and helping it rise without bouncing or jerking during cycling.

This is a Lift-O-Mat by Stabilus unit, which uses a longitudinal groove — a velocity manifold pressed into the tube wall — that lets gas flow around the piston with extension speed and damping tuned for this specific application. The groove profile gradually narrows toward the end of the stroke for a gentle, controlled stop.

  • Dynamic damping speed control: creates a fluid opening motion with no bouncing or jerking.
  • Corrosion-tested coatings: part coatings tested to automotive standards for corrosion resistance.
  • Easy installation: installs with no special tools required.
  • Based on the OE design: engineered for proper fit, form, and function.

Lift supports weaken with age; when the original struggles to hold the liftgate up or slams shut, replacing this one addresses that. For balanced operation, replace in pairs.

Frequently Asked Questions

What vehicles does this lift support fit?

It's a direct-fit replacement for the 2014-2019 KIA Soul and the 2015-2019 KIA Soul EV. Check the Buyer's Guide tab to confirm the fit for your vehicle.

What does dynamic damping speed control do?

It uses a groove pressed into the tube wall to control gas flow around the piston, creating a fluid opening motion with no bouncing or jerking and a gentle, controlled stop at the end of the stroke.

Should I replace both lift supports at once?

Stabilus recommends replacing in pairs for best results, since both supports age together and balanced operation keeps the liftgate rising and holding evenly.

How do I know my lift support needs replacing?

Common signs are a liftgate that won't stay open, slams down, or feels weak while rising. If a worn lift support is the cause, this replaces it.

Do I need special tools to install it?

No. This lift support is easy to install and requires no special tools. Consult your vehicle service information for the correct procedure.
