Design Features & Benefits

The Stabilus 304490 Cylinder Cargo incorporates several engineering features that set it apart from standard aftermarket springs:

• Precision Gas Chamber: The internal gas chamber is engineered to maintain a stable pressure throughout the full range of motion, preventing sudden jerks or uneven lifting.
• Durable Seals: High‑quality O‑rings and seals resist oil leakage and protect against environmental contaminants such as dust, water, and road salt.
• Low Maintenance: Once installed, the spring requires no lubrication or periodic adjustments, reducing long‑term upkeep costs.
• Enhanced Load Capacity: The 930 N rating allows the tailgate to support heavier cargo loads without compromising safety or performance.

Installation Guide

Installing the Stabilus 304490 Cylinder Cargo is a straightforward process that can be completed in under an hour with basic tools. Follow these steps for optimal results:

1. Remove Existing Spring: Use a socket wrench to detach the old gas spring from the tailgate frame and cargo area.
2. Clean Mounting Surfaces: Wipe away any debris or residue on both the mounting brackets and the new spring’s attachment points.
3. Position the New Spring: Align the Stabilus 304490 with the bolt holes, ensuring that the gas chamber faces the correct direction (usually indicated by a small arrow on the spring).
4. Tighten Bolts Securely: Use a torque wrench to tighten all mounting bolts to the manufacturer’s specified torque setting.
5. Test Operation: Open and close the tailgate several times to confirm smooth movement and proper lift height. Adjust if necessary by slightly loosening or tightening the bolts.

Performance Testing & Reliability

Extensive bench testing demonstrates that the Stabilus 304490 maintains consistent force output across a wide temperature range, from -20 °C to +60 °C. The spring’s internal design prevents gas leakage over thousands of cycles, ensuring long‑term reliability even in harsh driving conditions.

Maintenance & Troubleshooting

While the Stabilus 304490 is designed for minimal maintenance, users should periodically inspect the following:

• Seal Integrity: Check for any signs of wear or cracking on the O‑rings. Replace if necessary.
• Bolt Tightness: Re‑torque bolts every 12 months to counteract potential loosening due to vibration.
• Gas Pressure: If the tailgate feels sluggish, a professional service may be required to re‑pressurize the spring.

Warranty & Support (Product‑Only)

The Stabilus 304490 Cylinder Cargo comes with a comprehensive product guarantee covering manufacturing defects. For any technical queries or support, contact the manufacturer’s dedicated customer service line.
