How to Choose the Right GVM Upgrade for Your 78 Series LandCruiser Troopy

If you own a 78 Series LandCruiser Troopy, chances are you’re planning to load it to the roof and hit the road for a long trip. Between drawer systems, rooftop conversions, fridges, water tanks, spare tyres, and maybe even a bed setup, the Troopy’s biggest strength—its cavernous storage—can quickly turn into its biggest problem: weight.

That’s where a GVM (Gross Vehicle Mass) upgrade comes in. If you’ve added accessories and your Troopy is sagging on its haunches or sitting over its legal weight limit, you’re not just risking fines—you’re compromising safety, braking, and insurance coverage.

This guide breaks down the basics of GVM upgrades for Troopys, explains what to look out for, and highlights a few of the leading manufacturers currently offering Troopy-specific kits in Australia.

What Is a GVM Upgrade and Why It Matters for Your Troopy

GVM (Gross Vehicle Mass) is the maximum legal weight your vehicle can weigh when fully loaded—including passengers, fuel, gear, and accessories. When you fit a GVM upgrade, you’re replacing your vehicle’s suspension and supporting components with stronger, certified gear that allows it to safely carry more weight.

For Troopy owners, this is essential. Even with a modest setup - drawers, fridge, rear bar, water tanks - it all adds extra weight. A GVM upgrade restores payload, improves handling under load, and keeps you compliant on the road.

Why 78 Series Owners Almost Always Need a GVM Upgrade

Unlike a dual cab ute, the Troopy’s long body and storage volume encourage owners to pack everything and the kitchen sink. But the factory GVM (3510kg for the V8 2022-on) doesn’t leave much headroom once you start adding a bull bar, long-range fuel tank, and fully loaded set of drawers.

A GVM upgrade not only helps handle the weight, it transforms how the Troopy rides - especially over corrugations, or with heavy rear setups. For touring and off-grid builds, it’s arguably the first mod you should plan.

What to Look for When Choosing a 78 Series Troopy GVM Upgrade

When deciding on a GVM upgrade, focus on these five factors:

1. Target GVM Rating – How much extra capacity do you actually need?

2. Legal Compliance – Confirm your kit is certified for your state and model.

3. Cost & Installation – Kits typically range from $5,000–$8,000 installed, depending on brand and shock options.

4. Ride Quality – Heavier springs can make an empty Troopy ride stiff, so choose based on your loaded weight, not your dream payload.
