Car tailgate strut is an essential component that supports the opening and closing of a vehicle’s rear hatch or tailgate. Modern vehicles commonly use gas springs or electric lift supports depending on the vehicle’s comfort and automation level.
Gas Springs
Vehicle gas springs serve as industrial components and deliver support, cushioning, frenagem, height adjustment, and angle adjustment. It works by filling a sealed pressure cylinder with inert gas or an oil-gas mixture. The internal pressure becomes several times higher than atmospheric pressure, and the pressure difference between the piston rod area and piston area drives the piston rod movement.

Common Gas Spring Failures
1. Leakage
Leakage of the air spring can be caused by excessive air pressure inside the air spring, loose air tube joints, aging valves, and wear on the surface of the air spring.
2. Pressure loss
Due to prolonged use or problems with the structure of the air spring, the air spring may lose its original pressure, fail to maintain sufficient height, and even deform and sink.
3. Wear and tear
Common causes of wear and tear for the air spring include wear on the spring ball column and air bag structure, component aging, and the influence of environmental factors such as long-term high temperatures and humidity.
Electric Tailgate Struts
Auto electric tailgate strut is an electrically driven device. It converts the motor’s rotary motion into linear reciprocating movement. The tailgate ECU (Electronic Control Unit) controls the strut motor, enabling automatic extension and retraction to raise or lower the tailgate.

Vantagens:
1. The entire process quality management system, durabilidade, environmental adaptability and functional tests
2. High-quality springs and precise screws ensure safe and reliable use for a long time
3. Benchmarking against original factory standards, manufactured strictly in accordance with original factory standards
4. Using silent bearings and imported special lubricants to achieve low decibel operation
5. High-performance DC motors, with stable and powerful power output
Common Electric Tailgate Lift Problems
Car electric extension rod is part of the vehicle’s comfort system – the electric tailgate module. When there is a problem, it needs to be diagnosed using the vehicle’s diagnostic tool.
1. Abnormal sounds during door opening and closing: Internal springs deform or other components produce noise. The extension rod needs to be replaced.
2. The tailgate fails to close, and both exterior and interior tailgate buttons stop working.
3. The door opening and closing process suddenly stops or reverses.

Perguntas frequentes
- How long do tailgate gas struts last?
Mot quality gas struts last 3–8 years, depending on usage frequency, temperature, and environmental conditions.
- What causes a tailgate strut to fail?
Common causes include gas leakage, pressure loss, seal wear, corrosão, and component aging.
- Can electric tailgate struts be repaired?
Minor electrical issues may be diagnosed and repaired, but damaged motors, lead screws, or internal springs usually require complete strut replacement.
- How do I know if my tailgate gas spring is bad?
Signs include the tailgate falling unexpectedly, difficulty staying open, visible oil leakage, or reduced lifting force.
- Are aftermarket tailgate struts as good as OEM parts?
