What Are Tailgate Struts? Uses and Benefits Explained

Tailgate struts, also known as boot gas struts or tailgate gas springs, are essential vehicle components designed to support and control the opening and closing of a tailgate or boot lid.

By absorbing weight and reducing manual effort, tailgate struts improve convenience, safety, and long-term durability in everyday vehicle use.

How Do Tailgate Struts Work?

Tailgate struts operate using compressed gas, sometimes combined with hydraulic damping, to create controlled movement.

When the tailgate is opened, the struts provide stable lifting force, preventing sudden drops and reducing stress on hinges and mounting points.

Common Uses of Tailgate Struts

Tailgate gas struts are widely used across many vehicle types, including:

  • Cars and SUVs – Supporting boot lids and tailgates
  • Trucks and vans – Assisting with heavy rear doors
  • Campervans and caravans – Holding up storage compartments and rear panels
  • Industrial vehicles – Providing controlled access in commercial transport

Benefits of Tailgate Struts

  • Enhanced safety – Prevents accidental tailgate slamming
  • Improved convenience – Reduces effort when lifting heavy tailgates
  • Long service life – Designed for frequent use and harsh conditions
  • Custom fit options – Available in various lengths and force ratings

Choosing the Right Tailgate Strut

To ensure proper operation, selecting the correct tailgate strut depends on several key factors:

  • Load capacity – Must support the full weight of the tailgate
  • Length and stroke – Should match the opening and closing range
  • Material quality – Corrosion-resistant finishes for durability
