How to choose the right gas strut, the easy way
If you’ve ever tried to replace a gas strut on your canopy, camper, toolbox or trailer, you know the pain. There are hundreds of sizes, forces, and fittings out there, and it’s not always clear what suits your exact setup.
Choose wrong, and the result is frustration: a lid that slams shut, won’t open fully, or just feels off. That’s why UES Hardware has developed it's free Gas Strut Calculator - an easy-to-use online tool that helps you get it right the first time.
Let’s walk you through why choosing gas struts can be tricky, how the calculator works, and how to use it for your next DIY project.
Why Are Gas Struts So Hard to Choose?
Gas struts (also called gas springs) are clever little devices that use compressed gas to lift, lower, or hold panels and lids. You’ll find them on:
- 4WD canopies
- Ute and truck toolboxes
- Caravan hatches
- Camper trailer lids
- Marine access panels
- And even RV cabinets
But not all struts are created equal. To function correctly, the size, pressure and mounting angle need to match your application. Too strong? You’ll struggle to close it. Too weak? It won’t stay open. Too short? It won’t open far enough.
Unless you’ve got the original specs handy (and let’s face it — most of us don’t), it’s easy to end up guessing.
Here’s how it works:
- Enter your specs: Approximate weight of the lid or panel + the length of the panel (hinge to handle) + your preferred opening angle (e.g. 75° or 90°)
- Let the tool do the work: The calculator uses engineering logic to recommend the most suitable gas struts for your setup.
- Click to buy: You’ll see matching gas struts (with part numbers), pressure ratings, and mounting options — all ready to order online.
No spreadsheets, no trial-and-error, no tech degree needed.
Common Use Cases
The Gas Strut Calculator is perfect for a wide range of everyday jobs:
4WD Canopies & Ute Trays
Installing new side-opening windows or lift-up doors? Use the calculator to find the perfect struts to support heavy aluminium or steel lids.
Toolboxes
Replacing worn-out struts on your under-tray toolbox? Measure your lid and let the calculator recommend a pressure and size that fits.
Camper Trailers
Upgrading or rebuilding a rear-opening lid? The right gas struts will make lifting smoother and keep the lid open safely on uneven ground.
Caravan & RV Cabinets
Need your overhead storage doors to open smoothly and stay open? Use the calculator for compact, low-pressure strut options.
