Kilen Lesjöfors 8115642 Gas Spring, Boot

Overview

The Kilen Lesjöfors 8115642 Gas Spring, Boot is a high‑performance suspension component engineered to provide reliable lift and support for vehicle cargo areas. Designed with precision engineering, this gas spring delivers smooth operation, consistent force output, and long‑term durability under demanding conditions.

Design & Construction

The core of the Kilen Lesjöfors 8115642 Gas Spring is a robust steel cylinder that houses a sealed piston assembly. The piston rod is fitted with a hardened steel tip, ensuring minimal wear against the boot housing during repeated cycles. A high‑strength spring element inside the cylinder maintains constant pressure, while an integrated valve system regulates gas flow for controlled movement.

The outer shell is constructed from corrosion‑resistant alloy, providing protection against moisture and road salts. The boot itself is made of reinforced polymer that resists abrasion and flex fatigue, maintaining a tight seal around the piston rod throughout operation.

Performance Characteristics

• Force Range: 1,200–1,800 N (adjustable via spring tension)
• Lifting Capacity: Up to 350 kg of cargo weight without compromising structural integrity
• Travel Distance: 120–180 mm depending on configuration
• Cycle Life: Minimum 50,000 cycles under standard operating conditions
• Operating Temperature: –40 °C to +80 °C, ensuring performance in extreme climates

Installation Guide

Installing the Kilen Lesjöfors 8115642 Gas Spring involves a few straightforward steps that can be completed with standard automotive tools:

1. Secure Mounting Points: Verify that the mounting brackets on both the vehicle frame and the cargo area are clean, free of rust, and properly aligned.
2. Attach the Spring: Slide the piston rod into the boot housing, ensuring a snug fit. The spring should be positioned so that its natural tension aligns with the desired lift angle.
3. Locking Mechanism: Tighten the mounting bolts to the specified torque (typically 30–35 Nm) using a calibrated wrench or torque screwdriver.
4. Test Operation: Gently raise and lower the cargo area several times to confirm smooth movement and proper alignment. Adjust if necessary before final tightening.

Maintenance Tips

While the Kilen Lesjöfors 8115642 Gas Spring is designed for low maintenance, periodic checks can extend its service life:

• Visual Inspection: Look for signs of corrosion on mounting points and any cracks in the boot material.
• Lubrication: Apply a light silicone spray to the piston rod tip every 12 months to reduce friction.
• Seal Integrity: Inspect the boot seal for wear or deformation; replace if leakage is observed.

Compatibility

This gas spring is engineered to fit a wide range of vehicle models, particularly those requiring robust cargo area support. Common applications include:

• Cargo Vans and Minivans: Providing reliable lift for rear doors or tailgates.
• Light Commercial Vehicles: Enhancing payload capacity while maintaining structural integrity.
• Automotive Accessories: Used in aftermarket modifications where additional support is needed.
