Gas Strut Replacement Finder
Identify like-for-like replacements using the specifications on an existing gas strut.

Identify matching Trailer Parts Direct gas struts from the specifications of the gas strut you are replacing. This tool is for like-for-like replacement identification only.
1. Are you replacing an existing gas strut, or selecting gas struts for a new installation?
2. What Newton rating is printed on your existing gas strut?
Look for a sticker, etched or printed number on the strut body, usually shown as 100N, 300N, 500N or similar. Enter the same rating as the strut being replaced.
3. What is the fully extended length from centre of eye to centre of eye?
Measure the existing strut fully extended from the centre of one mounting point to the centre of the mounting point at the opposite end.
4. What is the compressed length?
Optional. If already known, enter the centre-to-centre compressed length. Do not remove or manually compress a strut merely to obtain this measurement.
5. What diameter is the strut shaft / gas cylinder?
This identifies the existing product series. The finder will prefer this series when equally close, but may show a different series if it is the closest same-Newton replacement within 50mm.
6. What end fitting is fitted to your existing gas strut?
7. Installation Environment
Protected examples include inside a toolbox, 4WD canopy, caravan tunnel boot or another primary structure preventing constant exposure. Exposed applications may use standard steel, but 316 stainless is recommended. Marine or other corrosive environments return 316 stainless steel only.
Gas Strut Safety - Read Before Removal or Installation
- Always independently support the lid, hatch, door or panel before removing or installing a gas strut. Never work beneath a panel supported only by gas struts.
- Gas struts contain pressurised gas and stored energy. Do not drill, puncture, cut, crush, weld, open or deliberately damage a pressurised gas strut. Follow the manufacturer's disposal instructions.
- Do not expose gas struts to excessive heat, flame or conditions outside the manufacturer's specified operating limits.
- Do not install or reuse a strut that is bent, dented, badly corroded, leaking, mechanically modified or otherwise damaged.
- Avoid scratching, painting, greasing, contaminating or damaging the piston rod.
- Do not subject the strut to side-loading, bending or misalignment. Existing mounting points and fittings must allow the strut to move freely without binding.
- Do not exceed the intended stroke or use the strut as a mechanical end stop unless the original application was designed that way.
- Keep hands and body parts clear of hinges, brackets, pinch points and moving panels during removal and installation.
- If the existing specifications cannot be positively identified, the replacement does not match, or you are unsure about safe removal or installation, stop and seek professional assistance.
