• Installation Type: Dual‑sided mounting – left and right side of the hood for symmetrical support
• Compatibility: Designed for a wide range of Volvo models including S60, S70, V70, XC70, and others that require a 400 N gas spring bonnet.

Design Features & Engineering Excellence

The Stabilus 8456LU incorporates several advanced design elements that set it apart from conventional hood springs:

• Precision Gas Chamber: The internal chamber is engineered to maintain a uniform pressure profile, reducing wear and extending service life.
• Robust Sealing System: Dual O‑rings and a high‑temperature sealant prevent gas leakage, ensuring consistent performance over thousands of cycles.
• Low Friction Bearings: Integrated low‑friction bearings minimize resistance during hood movement, providing a smooth user experience.
• Corrosion Protection: A multi‑layer protective coating resists rust and oxidation, making the spring suitable for marine or high‑humidity applications.
• Modular Mounting Brackets: The spring’s mounting interface is compatible with standard Stabilus brackets, simplifying installation and replacement.

Installation & Maintenance Guide

Installing the Stabilus 8456LU is straightforward for technicians familiar with hood suspension systems. Follow these steps to ensure optimal performance:

1. Preparation: Verify that the hood frame and mounting points are clean and free of debris.
2. Mounting Bracket Placement: Secure the left and right brackets onto the designated attachment points on the hood’s underside. Use torque specifications recommended by Stabilus (typically 12–15 Nm).
3. Spring Installation: Slide each gas spring into its bracket, aligning the threaded end with the mounting screw. Tighten to the specified torque.
4. Alignment Check: Open and close the hood several times to confirm smooth operation and proper alignment.
5. Periodic Inspection: Inspect for signs of wear or gas leakage every 12 months, especially in vehicles exposed to extreme temperatures.

Performance Benefits

• Consistent Load Distribution: The 400 N force rating ensures that the hood remains evenly supported, reducing stress on hinges and frame components.
• Extended Service Life: High‑quality materials and robust sealing reduce wear, often exceeding 50,000 opening cycles.
• Improved Safety: Reliable support prevents accidental hood lift or collapse, enhancing driver safety during operation.
