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 "Vehicles it fits" section for the full engine-level fitment.
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.

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 "Vehicles it fits" section 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.
