Stabilus 157987 Gas Spring – Bonnet

The Stabilus 157987 Gas Spring, commonly referred to as a bonnet gas spring, is a high‑performance component designed to support and lift the engine hood (bonnet) of various automotive models. It delivers reliable, smooth operation while protecting the vehicle’s interior from accidental hood opening.

Key Features & Technical Specifications

• Load Capacity: 680 Newton – sufficient for medium‑sized hoods such as those on Renault Scénic and Grand Scénic models.
• Stroke Length: 2645 mm – provides a comfortable opening range from fully closed to fully open positions.
• Operating Pressure: 70 kPa (typical for automotive gas springs of this class).
• Construction: Stainless steel cylinder and piston, sealed with high‑quality elastomeric seals to prevent corrosion and leakage.
• Mounting Options: Dual mounting brackets allow installation on both the hood frame and the vehicle’s chassis or body structure.
• Compatibility: Designed for a wide range of Renault models, including Scénic III (JZ0/1), Grand Scénic III, and various van conversions. It also fits other OEM vehicles that require a 680 N bonnet gas spring.

Design & Functionality

The Stabilus 157987 Gas Spring incorporates a robust internal gas chamber that expands when the hood is lifted, providing counter‑force to keep the bonnet in place. When the hood is closed, the spring’s compressed gas exerts pressure to hold it firmly shut, preventing accidental opening during driving or parking.

Its sealed piston design ensures long‑term reliability by minimizing wear and protecting against environmental contaminants such as dust, water, and road salt. The stainless steel construction resists rust, making the spring suitable for both domestic and marine applications where exposure to moisture is common.

Installation & Maintenance

• Installation: The spring comes with pre‑attached mounting brackets that align with standard bonnet hinge points. Installation typically involves securing the brackets to the hood frame, attaching the gas spring body, and connecting the other end to the vehicle’s chassis or a dedicated support plate.
• Maintenance: Routine inspection should focus on checking for visible corrosion, seal integrity, and proper alignment of mounting points. No regular lubrication is required due to the sealed design; however, any signs of leakage or abnormal noise warrant professional evaluation.

Applications & Vehicle Compatibility

The Stabilus 157987 Gas Spring is engineered for a variety of automotive platforms. Below are some representative applications:

• Renault Scénic III (JZ0/1) – 2014‑2016 models
• Renault Grand Scénic III – 2013‑2016 models
• Other OEM vehicles requiring a 680 N bonnet gas spring, such as certain van conversions and light commercial trucks.

Because of its standardized dimensions and load rating, the spring can also be used in aftermarket modifications where a reliable hood support system is needed.

Performance Benefits

• Enhanced Safety: By maintaining the bonnet in a closed position, it reduces the risk of accidental opening that could expose passengers to hot engine components or debris.
• Improved Comfort: The spring’s smooth operation allows drivers to open and close the hood with minimal effort, enhancing user experience during maintenance tasks.
• Durability: The high‑quality materials and sealed construction provide a long service life even under harsh operating conditions.

Conclusion

The Stabilus 157987 Gas Spring – Bonnet is a dependable, high‑performance component that delivers reliable hood support for a range of automotive models. Its robust construction, precise load rating, and ease of installation make it an ideal choice for both OEM installations and aftermarket replacements where safety, durability, and smooth operation are paramount.
