Every Kilogram Counts: Why RacksBrax Keeps Weight Down

Building a Touring 4WD & The GVM Equation

Why every kilogram counts when preparing your vehicle for serious adventure.

Building a touring 4WD is exciting.

Awning. Roof rack. Recovery boards. Fridge. Drawers. Spare wheel. Water. Camping equipment. Recovery gear. Shower tent. Tools.

Before you know it, all those individual accessories have added hundreds of kilograms to your vehicle.

And that’s when GVM - Gross Vehicle Mass - becomes something every serious 4WD owner needs to understand.

The Important Thing:

GVM isn’t just about the weight of your vehicle when you leave the factory. It includes the vehicle, occupants, fuel, luggage, accessories and everything else you’re carrying.

Every kilogram counts.

That’s one reason the RacksBrax approach to hitch design is so important.


Don’t Add Weight Just for the Sake of It

When you’re adding accessories to a 4WD, it’s easy to focus on strength and assume that heavier automatically means better.

But good engineering isn’t necessarily about making something heavier. It’s about designing a component to perform its intended function while using materials intelligently.

RacksBrax hitches are manufactured from UV-stabilised glass-reinforced nylon, an engineered material selected for strength, durability and outdoor performance.

The result is a robust quick-release hitch without adding unnecessary steel mass to the vehicle.

A standard RacksBrax HD Hitch is listed at approximately 1.2 kg, meaning the complete hitch solution adds only just over a kilogram to your setup.

That’s a small amount of additional weight when you’re considering the total mass of a touring vehicle.

And when you’re already trying to keep your build under GVM, small savings can matter.

GVM: The Weight You Don’t See Adds Up

The problem with vehicle accessories is that we tend to consider them individually:

  • An awning might weigh 20 or 30 kg.
  • A roof rack might weigh another 30 kg.
  • Recovery boards add more.
  • A fridge adds more.
  • Then there are batteries, drawers, water, camping equipment, passengers and luggage.

Individually, each addition may seem manageable. Together, they can push a vehicle much closer to its manufacturer’s GVM.

That’s why it makes sense to consider the weight of every accessory and mounting component when planning your build.

Choosing an engineered mounting system that adds only a small amount of additional weight is one way to make your overall setup more efficient.

Why Glass-Reinforced Nylon?

The RacksBrax hitch isn’t made from ordinary plastic. It uses UV-stabilised glass-reinforced nylon, specifically selected as an engineering material for the application.

Glass reinforcement provides the material characteristics required for a strong, durable hitch, while UV stabilisation is important because the product spends its life exposed to the Australian outdoors.

And there is another major benefit: It cannot rust.

Unlike a conventional steel hitch body, the glass-reinforced nylon RacksBrax hitch body doesn’t develop rust.

That gives you a combination of properties that makes sense for a roof-mounted 4WD accessory:

Strong Lightweight UV Stabilised Durable No Rust

Precision Engineering, Not Just Lightweight Construction

Keeping weight down is only useful if the component still performs its intended job. That’s where engineering becomes critical.

RacksBrax HD and XD Hitches have been developed by Australian mechanical and materials engineers using finite element analysis (FEA), with physical load testing undertaken to validate their specified loading.

The hitches are rated at 20 kg per load point.

So the objective isn’t simply to make the hitch lighter. It’s to engineer the right material, geometry and load path for the application.

That is the difference between lightweight engineering and simply making something light.

Keep Your Whole Setup in Mind

When planning a touring vehicle, the RacksBrax hitch is only one part of the equation. You need to consider the weight of the awning, roof rack, brackets and all other equipment, as well as passengers, fuel, water and luggage.

RacksBrax specifically states that loads must not exceed the rated capacity of the hitch, bracket, roof rack or vehicle manufacturer’s specifications.

That’s important.

A lightweight hitch doesn’t give you permission to overload your vehicle. Instead, it gives you another opportunity to avoid adding unnecessary weight while building your setup.

Always check your vehicle’s GVM and applicable axle-load limits and weigh your completed vehicle when necessary.

The Advantage of a Low-Weight Quick Release System

There’s also a broader benefit to keeping the RacksBrax system lightweight.

The whole point of RacksBrax is that your camping equipment doesn’t have to remain permanently attached to the vehicle.

  • ✔ You can remove your awning when you’re not camping.
  • ✔ You can remove recovery boards when you don’t need them.
  • ✔ You can remove other accessories and store them away.

That means you have the ability to change not only the configuration of your vehicle, but also the amount of equipment you’re carrying.

For a daily driver, that can make a lot of sense. For a touring vehicle approaching its GVM, it can make even more sense.

Don’t Carry What You Don’t Need

There’s a simple principle behind the RacksBrax modular system: If you’re not using it, why carry it?

A heavy touring build can be fantastic when you’re travelling remotely for weeks. But if you’re driving to work on Monday, do you really need every piece of camping equipment on the vehicle?

Removing an awning or other accessory when it’s not required can reduce the vehicle’s overall carried weight and also reduce aerodynamic drag. And with RacksBrax, removing accessories doesn’t have to mean spending an afternoon with a toolbox.

Every Kilogram Is Part of the Bigger Picture

GVM management isn’t about finding one magic product that solves your weight problem. It’s about making smart decisions across the entire vehicle:

  • Choose equipment carefully.
  • Know what everything weighs.
  • Don’t carry unnecessary gear.
  • Consider where weight is positioned.
  • Understand your roof-rack and axle limits.
  • And don’t forget the weight of the mounting hardware itself.

That’s where the RacksBrax approach makes sense.

A precision-engineered, UV-stabilised glass-reinforced nylon quick release awning hitch can provide the required functionality while adding only around 1.2 kg for the standard HD Hitch.

When you’re managing a heavily equipped 4WD, that’s weight you don’t need to add unnecessarily.

Lightweight Engineering. Serious Capability.

RacksBrax isn’t about building the heaviest bracket possible. It’s about engineering the right solution:

  • • Glass-reinforced nylon instead of a conventional steel hitch body.
  • • UV stabilisation for outdoor durability.
  • • No rust.
  • • Defined load ratings.
  • • FEA and physical load testing.
  • • Quick-release convenience.
  • • And a hitch system that adds only just over a kilogram in the standard HD Hitch configuration.

Because when you’re building a capable touring vehicle, strength matters - but so does weight.

Every Kilogram Counts

Your GVM is finite. Your payload is finite. So make every kilogram work for you.

Choose accessories that perform their job without adding unnecessary mass, remove equipment when you don’t need it, and build your touring setup around the way you actually use your vehicle.

RacksBrax - precision engineered, glass-reinforced nylon, no rust and designed to keep unnecessary weight out of your 4WD.
