Detailed Description

Stabilus 4B-029420 is a gas spring engineered for the Volkswagen Vanagon rear hatch application listed above. The measured compressed and extended lengths, along with the 8 mm rod and 18 mm tube dimensions, help ensure proper alignment and smooth hatch support. This part cross-references Monroe Shocks & Struts (e.g., 172286) for the same application.

For Volkswagen Vanagon owners replacing a worn hatch support, this gas spring restores controlled opening and holding force without changing the original mounting style. The metal blade rod end and plastic socket tube end match the specified attachment points for the vehicle fitment shown.

What It Helps Solve

• Rear hatch that drops instead of staying open
• Weak or inconsistent hatch lift support
• Slow, uneven hatch opening
• Excess effort needed to raise the hatch
• Noise or instability from a worn gas spring

Installation Notes and Tips

Verify the vehicle is a 1982-1991 Volkswagen Vanagon with the listed hatch configuration before ordering. Compare the original compressed length, extended length, and end fittings to the replacement part before installation. Support the hatch securely during service and confirm both attachment points seat fully after installation. Part number 4B-029420 should be matched to the exact application shown in the fitment data.
