Raise and hold your hood with smooth, controlled motion using the Stabilus Hood Lift Support 4B-678531 (also written 4B678531), a gas-charged lift support with dynamic damping speed control. It installs as a direct-fit replacement for the 2005-2009 Buick Allure and 2005-2007 Buick LaCrosse — see the Buyer's Guide tab for the full engine-level fitment.

  • Dynamic damping speed control: creates a fluid opening motion with no bouncing or jerking during cycling.
  • Lift-O-Mat design: uses a longitudinal groove (a velocity manifold) pressed into the tube wall so gas flows around the piston; the groove profile narrows toward the end of the stroke for a gentle, controlled stop.
  • Corrosion resistance: part coatings tested to automotive standards.
  • Easy service: measures 21.14 inches, installs with no special tools, and is built on the OE design for proper fit, form, and function. For best results, replace in pairs.

If a worn strut is why your hood drops, sags, or no longer holds itself open, this lift support replaces it to restore steady support.

Frequently Asked Questions

What vehicles does the Stabilus 4B-678531 hood lift support fit?

It's a direct-fit replacement for the 2005-2009 Buick Allure and 2005-2007 Buick LaCrosse. 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.

How long is this lift support?

The manufacturer lists it at 21.14 inches. Compare it to your original strut before ordering.

Should I replace both hood lift supports at once?

For best results, Stabilus recommends replacing them in pairs so both sides provide even, balanced support.

How can I tell my hood lift support needs replacing?

Signs include a hood that drops, sags, or no longer stays open on its own. If a worn strut is the cause, this support replaces it.
