Stabilus 5B-589639 Gas Strut for Mazda 3
Stabilus 5B-589639 is a gas strut built for controlled lift support on select Mazda 3 applications. It uses plastic socket connections and OE-style dimensions to match the original mounting points on supported vehicles, including Mazda 3 models with a rear spoiler.

Detailed Description
This Stabilus gas spring is engineered to provide smooth, controlled motion for the rear lift support application on the Mazda 3. The 440 N force rating, compact compressed length, and 281 mm extended length help it match the original support geometry on the listed vehicles. If you are replacing a worn lift support on a 2012-2013 Mazda 3 with spoiler or a 2010-2011 Mazda 3, 5B-589639 offers the correct fitment profile for that application.
This part cross-references Tuff Support 614096 for the same application.
What It Helps Solve
- Rear hatch or spoiler-mounted support that no longer holds position
- Slow, uneven, or weak lift action
- Drooping panel movement when opening the supported component
- Excess effort needed to raise or hold the hatch area
Installation Notes and Tips
Verify the existing strut length, end fittings, and mounting style before installation. Match the plastic socket connections to the vehicle’s original attachment points and confirm the application is for the correct Mazda 3 year range. For best results, replace the support when the hatch or spoiler begins to lose holding force rather than waiting for complete failure.
