Camper trailers are a favourite for people who love getting off the beaten track — and a good set of gas struts makes daily use easier and safer. This guide walks you through everything you need to know about camper trailer gas struts: how to measure them, which lengths and force ratings suit different hatches, plus installation, maintenance and replacement tips. Read on and you'll be ready to choose and fit the right struts for your trailer. (View our gas strut collection)

How do you measure camper trailer gas struts correctly?

Getting the measurements right is the first step to reliable performance. Correct dimensions ensure the strut lifts the hatch smoothly, sits in the correct range of travel and avoids overloading the unit. The critical dimensions are length, stroke and the mounting points — measure them carefully to prevent problems like poor lift or premature wear.

What are the key dimensions to measure for gas struts?

When you measure gas struts, focus on these three essentials:

• Length: The centre-to-centre distance between mounting points when the strut is fully extended.

• Stroke: How far the strut travels between fully compressed and fully extended — this determines available lift.

• Mounting points: The type, orientation and diameter of each end fitting — these affect fitment and movement.

Accurate measurements make sure the strut operates in its designed range and gives the support you need.

Which tools and techniques ensure accurate gas strut measurement?

Use simple, reliable tools and a careful technique for repeatable results:

• Measuring tape: Best for overall length and stroke — measure centre-to-centre with the strut fully extended and fully compressed.

• Calipers: Use these to check the diameter and fit of mounting studs or ball sockets.

• Templates: A paper or cardboard template of the mounting points helps confirm alignment before you buy or drill.

Take measurements more than once and note the mounting orientation so the new strut fits and works as intended (View our gas strut collection).

What gas strut sizes are best suited for camper trailers and caravans?

Size affects how much lift the strut gives and where it sits through its travel. Choosing the wrong length can reduce the effective lift or change how the hatch opens, so match the strut length to your hatch geometry and expected travel.

How do different gas strut lengths affect camper trailer performance?

Longer struts usually reach further and can support heavier hatches, while shorter struts suit lighter lids or where space is tight. The right length delivers predictable lift, better stability and an easier opening action — pick the length that matches the hatch weight and mounting layout.

What are common gas strut size options available at Schutts Industrial?

Schutts Industrial stocks common lengths to suit a wide range of camper and caravan hatches:

• 300mm: Good for small, lightweight lids and compact storage compartments.

• 400mm: A versatile size for many mid‑sized hatches — balances travel and lift.

• 500mm: Suited to larger or heavier lids where extra reach and support are needed.

Choose the length that fits your hatch geometry and the travel you require.

How to select the right force rating?

The force rating — shown in Newtons (N) — tells you how much lift the strut provides. Selecting the correct force ensures the hatch opens smoothly and stays supported without placing excess stress on the strut or mounts.

What is gas strut force and how is it calculated?

Force is primarily driven by the weight of the hatch, the mounting position and the angle of operation. A practical approach is to estimate the effective load at the mounting point (considering leverage) and choose a strut with a force rating that comfortably supports that load. Remember the static hold force is a starting point — friction, leverage and operating angle usually mean you’ll need a margin above the calculated value.

When in doubt, consult our team or use a conservative safety margin to avoid under‑specifying the strut (View our gas strut collection).

Which force ratings are recommended for heavy duty and lightweight trailers?

Use these general ranges as a guide:

• Heavy duty trailers: Typically 600N to 1200N, depending on hatch weight and leverage.

• Lightweight trailers: Often 200N to 600N for smaller hatches and storage lids.

Match the force to your hatch weight and mounting layout, and ask for help if you’re unsure.

What are the best practices for installing and maintaining?

Correct installation and routine care keep gas struts working longer and reduce the chance of failure. Follow solid mounting practices and a simple inspection routine for reliable performance.

How do you properly mount gas struts using brackets and ball joints?

Follow these steps for a secure fit:

• Select the right brackets: Use brackets designed for your strut type and mounting points.

• Positioning: Fit the struts at the recommended angle so the hatch opens smoothly and the strut works through its correct travel.

• Secure fastening: Tighten fasteners to the specified torque and use lock‑washers or thread locking where appropriate.

Double‑check alignment and movement before finishing — and always support the hatch while you work (View our gas strut collection).

What maintenance tips extend the life of a gas struts?

Regular checks and simple care will extend service life:

• Inspect regularly: Look for leaks, bent rods, corrosion or loose fittings.

• Clean the struts: Wipe off dirt and grit that can damage seals.

• Lubricate mounting points: Lightly grease pivots and brackets — but do not lubricate the piston rod itself, as oils can harm the seal.

Routine attention prevents small issues from turning into failures on the road.

When and how should you replace trailer gas struts?

Struts wear out over time. Replacing them promptly keeps hatches safe and avoids damage to the trailer or contents.

What are signs that your caravan gas struts need replacement?

Watch for these common signs:

• Loss of lift: The hatch no longer stays open or feels weak.

• Visible damage: Cracks, oil leaks or severe corrosion.

• Unusual noises: Popping, grinding or scraping during operation.

If you see any of these, plan to replace the struts before they fail completely.

How can you safely replace gas struts on your camper trailer hatch?

Replace struts safely with a simple step‑by‑step approach:

• Gather tools: A socket set, retaining‑clip tools and safety glasses are usually enough.

• Support the hatch: Use a prop or have an assistant hold the hatch open while you work.

• Remove old struts: Release retaining clips or bolts and remove the strut from its brackets.

• Install new struts: Fit and secure the new struts, orienting them as recommended (piston rod down helps preserve the seal) and check movement before finishing.

Test the hatch through its full travel to confirm smooth, secure operation.

Which accessories and materials enhance performance?

Good mounts and the right materials improve durability and make installation simpler. Choose accessories that match the load and the environment.

What mounting bracket options are compatible with camper trailer gas struts?

Common bracket choices include:

• Standard brackets: Reliable for most everyday applications.

• Adjustable brackets: Let you fine‑tune the strut angle and position for better lift.

• Heavy‑duty brackets: Built for larger lids and heavier loads.

Pick brackets rated for your strut and load to ensure a long service life (View our gas strut collection).
