Key points about tailgate lift cylinders

A tailgate lift cylinder, also known as a tailgate strut or tailgate lift support, is a component commonly used in vehicles to assist in the controlled opening and closing of the tailgate or rear hatch. Here are key points about tailgate lift cylinders:

1. Function: The primary function of a tailgate lift cylinder is to support and control the movement of the tailgate or rear hatch. It helps in lifting the tailgate when it is opened and provides resistance to prevent it from slamming shut when closing.

2. Gas Spring Design: Tailgate lift cylinders are often gas springs or hydraulic cylinders. Gas springs use compressed gas, usually nitrogen, to provide the necessary force for lifting and supporting the tailgate.

3. Hydraulic Design: In some cases, tailgate lift cylinders may be hydraulic, using a fluid-filled cylinder to achieve the same lifting and supporting functions.

4. Controlled Movement: The design of tailgate lift cylinders ensures that the opening and closing of the tailgate are controlled and gradual. This prevents sudden movements that could cause injury or damage to the vehicle.

5. Durable Construction: Tailgate lift cylinders are typically constructed with durable materials such as steel or aluminum to withstand the repetitive forces and environmental conditions they may be exposed to.

6. Replacement: Over time, tailgate lift cylinders may wear out or lose their effectiveness. When this happens, it's important to replace them to maintain the proper functioning of the tailgate. Signs of wear include difficulty in lifting the tailgate or the tailgate not staying in the open position.

7. Compatibility: When replacing tailgate lift cylinders, it's crucial to ensure compatibility with the specific make and model of the vehicle. Different vehicles may have different tailgate lift cylinder designs and specifications.

8. Installation: Replacing tailgate lift cylinders is generally a straightforward process. However, it's recommended to follow the vehicle manufacturer's instructions or consult a professional for proper installation.

9. Safety: Properly functioning tailgate lift cylinders contribute to the safety of the vehicle. They prevent the tailgate from falling unexpectedly, reducing the risk of injury or damage.

If you experience issues with your tailgate or suspect that the lift cylinders are not working correctly, it's advisable to have them inspected and replaced if necessary. Regular maintenance checks can help ensure the continued reliable performance of the tailgate lift system in your vehicle.
