Whether it is a heavy aluminium lid, the loading ramp of a horsebox, or the side hatch of a catering trailer – manual lifting requires enormous force without assistance. High-quality gas struts (also known as gas springs or dampers) act as a clever lifting aid. They safely absorb the weight, assist the opening process, and reliably hold the lid in position. At trailer.one, you will find the right gas strut for every weight class.

Finding the Right Gas Strut: Length and Force (Newton)

For a gas strut to function perfectly, its technical parameters must match exactly. In our range, you will find dampers sorted by:

• Extension Force (N): Specified in Newtons (e.g., 500N, 1000N, or 1500N) – crucial for the weight the strut can support.
• Stroke & Total Length: Measured from centre-of-eye to centre-of-eye when fully extended.
• End Fittings: Whether robust ball sockets (e.g., for 10mm or 13mm ball studs), eyelets, or threaded ends for custom fabrications.

We stock original spare parts from leading manufacturers like Stabilus, AL-KO, or Knott, as well as universal solutions for various applications.

Accessories: Ball Studs, Mounting Plates, and Brackets

A gas strut is only as good as its anchor point on the chassis or bodywork. Whether you are repairing an existing system or upgrading your trailer with a new lid, we offer the matching mounting accessories: from sturdy weld-on or bolt-on plates to high-tensile ball studs and safety clips.

Pro Tip: It is highly recommended to replace gas struts on lids or hatches in pairs. Since gas cylinders slowly lose pressure over the years, replacing only one side causes uneven load distribution, which can warp the mechanism or overload the new damper.
