Automotive gas springs—also known as gas-filled springs or gas struts—are self-contained cylinders that use pressurized nitrogen gas to create a pushing or damping force. They are commonly used in vehicles to:
- Assist the lifting of heavy panels such as hoods and tailgates
- Provide smooth and controlled opening/closing of compartments
- Reduce the physical effort required for access panels or seats
- Improve safety by preventing sudden slams or free-falls
Gas springs are essential in modern vehicle design for ergonomic operation, improved durability, and a premium user experience. Compared to traditional coil springs or mechanical hinges, gas springs offer precise control, minimal maintenance, and a sleek, compact design.
