Formula 4×4 GVM upgrades: Increase your payload legally with Fulcrum Suspensions

If you’ve added a bull bar, winch, canopy, drawer system, long-range fuel tank, dual battery setup or tow a caravan, there’s a good chance your 4WD is carrying more weight than the factory intended.

A Formula 4×4 GVM upgrade from Fulcrum Suspensions is designed to legally increase your vehicle’s Gross Vehicle Mass (GVM), giving you additional payload capacity while maintaining safe handling and compliance with Australian regulations.

Available exclusively through Fulcrum Suspensions, every GVM upgrade kit is Australian engineered, professionally installed and certified, making it a complete solution for touring, towing and work vehicles.

What is a GVM upgrade?

A Gross Vehicle Mass (GVM) upgrade increases the maximum legal weight your vehicle is permitted to carry.

Your GVM includes:

• The vehicle itself
• Driver and passengers
• Camping gear
• Tools and equipment
• Bull bars and winches
• Canopies and drawer systems
• Long-range fuel tanks
• Roof racks
• Tow ball download from a caravan or trailer

Many modern 4WDs quickly exceed their factory payload once common accessories are fitted. A professionally engineered GVM upgrade helps restore compliance while improving suspension performance under load.

Formula 4×4 GVM upgrades

Formula 4×4 GVM upgrades are supplied as complete suspension systems rather than simply replacing one or two components.

Each GVM upgrade kit includes:

• Upgraded front suspension
• Matched rear suspension components
• Engineering approvals
• Compliance plates where required
• ADR-compliant certification

Because the entire suspension system is designed to work together, the vehicle remains balanced while carrying heavier loads.

Formula 4×4 GVM kits are available for many of Australia’s most popular vehicles, including Toyota Hilux, Toyota LandCruiser, Ford Ranger, Isuzu D-MAX, Mitsubishi Triton and Nissan Patrol.

Upgrade capacities vary depending on the vehicle and intended use, with Fulcrum helping determine the most suitable option before installation.

Two front suspension options

Formula 4×4 offers two different front suspension configurations.

Remote Reservoir Shocks

Designed for serious touring and off-road use, Remote Reservoir Shocks feature external reservoirs that increase oil capacity and improve heat dissipation.

This helps maintain consistent damping performance during:

• Long corrugated roads
• Heavy towing
• Remote touring
• High-load off-road driving

Height Adjustable ReadyStruts

Height Adjustable ReadyStruts allow ride height to be fine-tuned to suit changing accessory loads.

They’re particularly useful if you’re adding components over time such as:

• Bull bars
• Winches
• Driving lights
• Battery systems

The adjustable design also simplifies installation and future suspension adjustments.

Formula 4×4 GCM upgrades

In addition to its GVM upgrade range, Fulcrum Suspensions now offers GCM upgrades for selected vehicles.

A GCM upgrade increases the allowable Gross Combination Mass, enabling some vehicles to legally tow heavier combinations while remaining compliant.

Formula 4×4 GCM upgrades are currently available for the Toyota LandCruiser 300 Series, with additional applications under development.

Finite Element Analysis (FEA) is also used during development to ensure every component is engineered for long-term durability under increased loads.

The same certified process is followed for all GCM upgrades.

How much does a Formula 4×4 GVM upgrade cost?

Pricing depends on vehicle make and model, suspension configuration and upgrade capacity. But as a general guide, Formula 4×4 GVM upgrades typically range from around $5,000 to $8,000 fully installed.

Pricing includes:

• Installation
