What is a GVM Upgrade?​

A Gross Vehicle Mass (GVM) upgrade involves increasing the maximum weight that a 4x4 vehicle can legally carry. This upgrade is particularly beneficial for off-road enthusiasts, overlanders, and commercial users. Here’s why:

​

• Increased Payload Capacity: A GVM upgrade enables your vehicle to carry heavier loads, making it more versatile for transporting equipment, camping gear, or supplies for long-distance travel.

• Improved Safety: Reinforcing the chassis, suspension, and brakes to accommodate the increased weight enhances stability and handling, reducing the risk of accidents, particularly on rough terrain.

• Enhanced Towing Capability: With a higher GVM, your vehicle can safely tow heavier trailers, caravans, or boats without compromising performance.

• Extended Range: The ability to carry more fuel, water, and supplies allows for longer trips without frequent refueling stops.

• Better Off-Road Performance: Improved suspension components increase ground clearance, making the vehicle more capable of handling tough terrains.

• Customization Options: Tailor your GVM upgrade with heavy-duty springs, shocks, and other aftermarket accessories to meet your specific needs.

• Warranty Preservation: Engineered to meet legal and manufacturer guidelines, many GVM upgrades maintain the vehicle’s warranty.

• Increased Resale Value: A vehicle with a GVM upgrade is often seen as an investment, leading to higher resale value.

• Versatile Application: Beneficial for recreational and commercial vehicles alike, GVM upgrades enhance carrying capacity for tools and equipment.

• Compliance with Regulations: Helps your vehicle adhere to weight regulations, avoiding potential fines.

What is a Coil Conversion?

A coil conversion replaces the leaf springs of a vehicle's suspension with coil springs. This modification can offer several benefits:

​

• Improved Ride Comfort: Coil springs provide a smoother ride by absorbing bumps more effectively than leaf springs.

• Enhanced Handling: Coil springs offer better flexibility and control, improving vehicle handling, especially on uneven terrain.

• Increased Flexibility: Coil springs adapt more efficiently to various loads and road conditions, providing a consistent driving experience.

• Better Off-Road Performance: Enhanced suspension articulation from coil springs allows for improved traction and stability on rough terrain.

• Customization Potential: Coil conversions enable users to adjust the suspension setup to meet specific needs, offering more flexibility in ride height and load capacity.
