Womala Rear Cover Support Rod OE 31278322 Gas Spring for Volvo V50 2004-2012

The Womala Rear Cover Support Rod (OE Number: 31278322) is a key component designed exclusively for the Volvo V50, responsible for effortlessly lifting and securely holding the rear cover (trunk lid or tailgate) in the open position.

Constructed with a high-strength steel cylinder and a precision-sealed piston, it utilizes compressed nitrogen gas to generate a controlled force that counteracts the cover's weight (typically 8-12 kg). Unlike generic support rods, this OE part features factory-calibrated pressure (approximately 3-5 bar) and end fittings that perfectly match the V50's rear cover hinges and body mounting points. Its corrosion-resistant coating (electrophoretic deposition) protects against rust and road salt, ensuring smooth operation even in harsh weather conditions (-40°C to 80°C).

• Lifting Assistance: Provides consistent upward force to lift the rear cover with minimal effort, reducing strain on the user when opening—especially useful for repeated use (e.g., loading/unloading cargo).
• Secure Positioning: Holds the rear cover firmly in the open position, preventing sudden closure due to gravity or wind, which enhances safety and convenience during loading.
• Smooth Operation: The gas-charged design ensures gradual, jolt-free movement when opening or closing the cover, preventing damage to the hinges or body panels.
• Durability: Withstands thousands of cycles without losing pressure, maintaining performance over the vehicle's lifespan—typically 100,000+ km of use.

This gas spring is specifically engineered for:

As a direct OE replacement, it installs seamlessly using the vehicle's original mounting hardware (ball joints or clips), requiring no modifications. Regular inspection for gas leakage (e.g., reduced lifting force, cover sagging) or corrosion is recommended—weakened springs can cause the rear cover to close unexpectedly, posing safety risks. Replacement is straightforward and restores full functionality to the rear cover system.
