Gas Strut Replacement Finder

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.

Replacement identification only. This finder does not calculate, design or specify gas struts for new installations and must not be used to increase or decrease the Newton rating of an existing installation.

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.

Before ordering: independently confirm the Newton rating, extended length, compressed length where available, shaft/cylinder size, material and end fittings against the existing gas strut. If the specifications do not match, do not assume a similar-looking strut is suitable.

I confirm that I am replacing an existing gas strut and have checked the specifications entered against the strut being removed. I understand this finder identifies matching catalogue products and does not design or certify my installation.

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.

Designed for both replacement installations and new builds, the Dunn & Watson 250mm Gas Strut offers a practical solution for supporting hinged panels and storage lids. Its compact construction makes it suitable for applications where dependable lifting assistance is required without occupying excessive space.

Built for Australian Touring Conditions

4WD canopies, toolboxes and camper trailers are regularly exposed to dust, moisture and harsh outdoor environments. To help withstand these conditions, Dunn & Watson gas struts incorporate nitrocarburised shafts that provide increased resistance to rust and surface wear.

The result is a durable shaft finish designed to reduce wear on the internal seals and minimise the risk of premature pressure loss.

Advanced Internal Gas Strut Technology

Each strut incorporates a premium L-shaped skeleton oil seal and high-purity nitrogen filling. Together with enhanced internal lubrication, these features assist in maintaining smooth movement, reliable pressure retention and consistent lifting performance.

Versatile Mounting and Force Options

Available in multiple force ratings between 100N and 400N, the 250mm gas strut is suited to a range of caravan, camper trailer, automotive and industrial applications.

Whether you’re replacing worn gas struts on an existing toolbox or fitting new gas springs to a custom 4WD storage system, Dunn & Watson delivers a reliable, quality-engineered component.
