Stabilus 502621 Gas Spring, boot-/cargo area

Stabilus 502621 Gas Spring – Boot/Cargo Area

The Stabilus 502621 Gas Spring is a high‑performance hydraulic actuator designed specifically for automotive rear‑door and cargo‑area applications. It delivers smooth, controlled lift and support for the tailgate or hatch, ensuring reliable operation under varying load conditions.

Key Functional Characteristics

• Force Rating: 1,140 N – sufficient to counteract the weight of a fully loaded cargo area while maintaining a gentle lift profile.
• Stroke Length: Optimised for standard hatch and tailgate designs, providing full extension without over‑travel.
• Operating Temperature Range: -40 °C to +120 °C – suitable for all climates and automotive environments.
• Pressure Capacity: Up to 200 bar – ensuring durability and resistance to pressure spikes during rapid opening or closing.

Design Features

The spring incorporates a robust aluminium housing that protects the internal piston from corrosion and mechanical damage. The piston is sealed with high‑quality O‑rings, preventing fluid leakage and maintaining consistent pressure over thousands of cycles. A dual‑side mounting configuration allows installation on either the driver or passenger side of the vehicle, offering flexibility for OEM and aftermarket applications.

Installation Compatibility

This component is engineered to fit a wide range of vehicles, including:

• BMW X6, X7 (E71/E72) – both front‑wheel and all‑wheel drive variants.
• Other luxury and performance models that require a high‑force gas spring for the rear hatch or cargo area.

Its modular design means it can replace standard mechanical hinges, providing an immediate upgrade in lift quality without extensive chassis modifications.

Performance Benefits

• Consistent Lift: The gas‑filled piston delivers a steady force throughout the entire stroke, preventing sudden jerks or stalls.
• Reduced Wear: By eliminating mechanical friction between hinge components, the spring extends the lifespan of the tailgate assembly.
• Improved Safety: Controlled descent reduces the risk of accidental closure and potential injury to occupants or cargo.
• Enhanced Aesthetics: The sleek aluminium finish complements modern vehicle interiors, maintaining a premium look.

Maintenance Guidelines

Although designed for long‑term reliability, periodic inspection is recommended to ensure optimal performance:

1. Check the piston seals for any signs of wear or leakage.
2. Verify that mounting bolts remain tight and free from corrosion.
3. Inspect the tailgate latch mechanism for smooth operation in conjunction with the spring.

Routine maintenance extends the service life beyond typical automotive expectations, making it a cost‑effective choice for both OEMs and aftermarket installers.

Technical Specifications Summary

Conclusion

The Stabilus 502621 Gas Spring represents a pinnacle of engineering for automotive rear‑door applications. Its combination of high force, durable construction, and versatile mounting options make it an ideal solution for vehicles that demand reliable, smooth lift performance in both everyday use and demanding conditions.
