Stabilus Back Glass Lift Support P/N:4B-257921

$22.99

Description

Keep the rear glass gliding up and holding open with the Stabilus Back Glass Lift Support 4B-257921, a gas-charged lift support with dynamic damping speed control. It's a direct-fit replacement for the listed applications, including the 2018-2024 Ford Expedition and 2018-2024 Lincoln Navigator — see the Buyer's Guide tab for the full engine-level fit.

Dynamic damping speed control: creates a fluid opening motion with no bouncing or jerking during cycling.
Lift-O-Mat design: a longitudinal velocity-manifold groove lets gas flow around the piston, and the groove narrows toward the end of the stroke for a gentle, controlled stop.
Corrosion-resistant coatings: part coatings tested to automotive standards for corrosion resistance.
Based on the OE design to help ensure proper fit, form and function; easy to install and requires no special tools.

If a worn or gas-depleted original is letting the back glass sag or drop, this replaces it. For best results, replace lift supports in pairs so both sides raise and hold the glass evenly.

Frequently Asked Questions

What does this lift support do?

It's a gas-charged lift support that raises the rear back glass and holds it open, using dynamic damping speed control for a fluid, controlled opening motion.

Which vehicles does the 4B-257921 fit?

It's a direct-fit replacement for the listed applications, including the 2018-2024 Ford Expedition and 2018-2024 Lincoln Navigator. Check the Buyer's Guide tab for the full engine-level fitment.

How do I know my lift support needs replacing?

Signs may include the back glass drifting down, failing to stay open, or opening with a bounce or jerk. If a worn or gas-depleted support is the cause, this replaces it.

Should I replace both supports at once?

For best results, replace lift supports in pairs so both sides raise and hold the glass evenly and with matched damping.

Are special tools required to install it?

No. It is easy to install and requires no special tools, and it is based on the OE design to help ensure proper fit, form and function.
