Lesjöfors 8155412 Gas Spring, Boot

Lesjöfors 8155412 Gas Spring – Boot

The Lesjöfors 8155412 Gas Spring – Boot is a high‑performance hydraulic actuator designed to provide smooth, controlled lift and support for vehicle cargo areas. Whether you are working on a sedan, hatchback, or light commercial vehicle, this gas spring delivers reliable performance in a compact form factor.

Core Design Features

The 8155412 model incorporates several key engineering elements that set it apart from standard lift mechanisms:

• Robust Steel Construction: The cylinder and piston are forged from premium alloy steel, ensuring durability under repeated load cycles.
• Precision‑Milled Seals: Dual O‑ring seals prevent gas leakage while maintaining a smooth stroke.
• Optimized Gas Charge: The internal pressure is calibrated to provide the exact lift force required for typical cargo loads, reducing strain on the vehicle’s frame.
• Compact Footprint: With a length of just 120 mm and a diameter of 35 mm, it fits easily into tight mounting spaces without compromising performance.

Functional Benefits

Installing the Lesjöfors 8155412 Gas Spring in your vehicle’s boot area offers numerous advantages:

• Consistent Lift Height: The spring maintains a steady height regardless of load weight, ensuring that the cargo area remains level and accessible.
• Reduced Mechanical Stress: By absorbing shock loads, it protects hinges, seals, and surrounding components from wear.
• Easy Installation: Standard mounting brackets are included, allowing for a quick swap‑in with minimal tools.
• Low Maintenance: The sealed design eliminates the need for regular lubrication or gas refilling.

Compatibility Overview

The 8155412 is engineered to fit a wide range of vehicle models, particularly those from the MAZDA family. Commonly matched part numbers include:

• BC1C-63-620D
• BC1C-63-620C
• BC1C63620B
• BC1C63620C
• BC1C63620D

These identifiers correspond to specific hinge assemblies and cargo area configurations, ensuring a precise fit without the need for custom fabrication.

Installation Procedure

1. Preparation: Secure the vehicle on a flat surface and remove any existing lift mechanism. Inspect mounting points for damage or corrosion.
2. Mounting Bracket Attachment: Fasten the supplied bracket to the hinge frame using the provided bolts. Torque specifications are typically 20 Nm.
3. Gas Spring Placement: Align the piston head with the bracket’s mounting plate, ensuring that the gas cylinder is oriented correctly (gas side facing outward).
4. Securing the Actuator: Tighten all fasteners to the manufacturer’s recommended torque. Verify that the spring moves freely without binding.
5. Functional Test: Lower and raise the cargo area several times, checking for smooth operation and proper height retention.

Maintenance Tips

• Inspect seals annually; replace if any signs of wear are visible.
• Check bolt torque every 10,000 km to prevent loosening due to vibration.
• Avoid over‑loading the cargo area beyond the specified weight limit (typically 200 kg) to preserve spring integrity.
