• Stroke Length: 120–180 mm, allowing full lift of the trunk lid while maintaining a compact profile
• Operating Temperature: –40 °C to +80 °C, ensuring performance in diverse climates
• Material Composition: High‑strength steel alloy with corrosion‑resistant coating; internal gas chamber filled with nitrogen for stable pressure
• Mounting Configuration: Dual‑point attachment—one end secured to the trunk frame, the other to a custom boot housing that aligns with the vehicle’s rear chassis
• Installation Compatibility: Designed to fit within existing mounting brackets on Jaguar XK8 models; no major modifications required

Design Philosophy: Reliability Meets Longevity

The Lesjofors 8141402 is built around a sealed gas chamber that maintains pressure over thousands of cycles, preventing leakage and ensuring consistent lift force. The spring’s internal geometry—specifically the coil diameter and pitch—is optimized to reduce wear on both the spring itself and the surrounding chassis components.

Its compact boot housing protects the gas spring from environmental contaminants such as dust, moisture, and road debris. This protective enclosure also simplifies installation by providing a ready‑made mounting interface that aligns with standard vehicle rear frames.

Installation & Maintenance Guide

1. Preparation: Secure the vehicle on a flat surface; remove any existing trunk lid support components if present.
2. Mounting: Align the boot housing with the rear chassis bracket. Fasten using the supplied bolts, ensuring torque specifications are met to avoid over‑tightening.
3. Connection: Attach the gas spring’s free end to the trunk lid frame via the integrated mounting plate. Verify that the spring is positioned correctly to avoid binding during operation.
4. Testing: Operate the trunk lid manually, observing smooth lift and descent. Confirm that the spring provides adequate support without excessive resistance.
5. Routine Checks: Inspect for any signs of wear or damage every 12 months. Replace if corrosion is detected on mounting points or if the gas spring exhibits reduced lift force.

Performance Highlights

• Consistent Lift Force: Maintains a steady pressure curve, preventing sudden jerks when opening or closing the trunk lid.
• Low Maintenance: Sealed nitrogen chamber eliminates the need for periodic refilling or lubrication.
• Durability: Designed to withstand over 20,000 lift cycles without significant degradation.
• Weather Resistance: Corrosion‑resistant coating ensures longevity even in high‑humidity or salt‑spray environments.
