The Stabilus 8413HV Gas Spring is a high‑performance, precision‑engineered component designed to provide reliable lift support for the rear boot or trunk of a vehicle. It delivers a consistent force of 420 N, ensuring smooth and controlled opening and closing actions.

Key Functional Characteristics

• Force Output: 420 Newton – ideal for medium‑to‑heavy duty applications such as passenger cars, station wagons, and light commercial vehicles.
• Stroke Length: 500 mm – offers ample travel to accommodate various boot designs while maintaining a compact profile.
• Operating Temperature Range: -40 °C to +120 °C – suitable for diverse climatic conditions.
• Material Composition: High‑strength steel alloy with corrosion‑resistant coating, ensuring durability and longevity.
• Installation Compatibility: Designed to fit a wide range of models, including Audi A3, A4, B5 Avant, S4, RS4, and other vehicles that require a 420 N gas spring.

Engineering Design Features

The Stabilus 8413HV incorporates several advanced design elements:

1. Dual‑End Sealing: Both ends of the spring are sealed to prevent gas leakage, maintaining consistent pressure over time.
2. Pre‑Compressed Gas Chamber: The internal chamber is pre‑compressed with nitrogen, providing a smooth force curve and reducing wear on mounting hardware.
3. Threaded Mounting Flanges: Standardized flanges allow for straightforward installation without the need for custom adapters.
4. Low Vibration Profile: The spring’s geometry minimizes vibration, contributing to a quieter boot operation.

Performance Benefits

• Enhanced Load Capacity: The 420 N force ensures that even fully loaded trunks can be opened with minimal effort.
• Consistent Operation: Precise gas pressure control delivers a uniform opening speed, improving user experience.
• Extended Service Life: Robust construction and protective coatings reduce the likelihood of corrosion or mechanical failure.
• Easy Maintenance: The design allows for quick inspection and replacement if necessary, without extensive disassembly.

Installation Overview

Installing the Stabilus 8413HV Gas Spring involves aligning the threaded flanges with the vehicle’s mounting points and securing them with appropriate fasteners. The spring should be positioned so that its force vector aligns with the boot’s opening axis, ensuring optimal performance.

Step‑by‑Step Guide

1. Remove any existing gas spring or retaining hardware from the boot assembly.
2. Align the new spring’s mounting flanges with the pre‑drilled holes on the vehicle frame.
3. Screw in the fasteners, tightening to the manufacturer’s torque specifications.
4. Test the boot operation by opening and closing it several times to confirm smooth movement.
5. Inspect for any signs of gas leakage or abnormal vibration; adjust if necessary.
