RAM, Silverado & F-Truck GVM Upgrades in Melbourne | CTO Industries Australia
If you’re driving a RAM, Chevrolet Silverado, or Ford F-Truck in Australia and pushing the limits of your load capacity, a GVM (Gross Vehicle Mass) upgrade isn’t just a luxury—it’s a necessity. At CTO Industries, we provide federally approved GVM upgrades engineered for the demands of Australian roads and terrain, helping drivers increase their payload capacity while remaining compliant, safe, and legal.
From Adelaide to Brisbane, Canberra to Perth, and everywhere in between, our GVM upgrade kits for American trucks are trusted by fleet operators, off-road adventurers, tradies, and touring families looking to boost their load-carry capability.
GVM (Gross Vehicle Mass) refers to the maximum allowable weight a vehicle can legally carry, including its own weight, passengers, fuel, fluids, accessories, and cargo. Many American imports like the RAM 1500, Silverado 2500HD, and Ford F-Series come into Australia with downgraded GVM ratings to meet local regulations.
At CTO Industries, our GVM upgrade kits are designed to increase that legal limit, providing a compliant solution for carrying more weight, towing safely, and protecting your vehicle’s suspension, driveline, and braking systems under heavy-duty use.
Whether you’re loading up with drawers, bull bars, canopies, long-range fuel tanks, or preparing for off-road touring, the additional weight can easily exceed your vehicle’s stock GVM. Overloading can lead to:
Suspension sagging
Brake fade
Poor steering control
Tyre blowouts
Fines and voided insurance
Compromised safety and stability
Our GVM upgrades are tailored to restore confidence, increase payload, and enhance performance—keeping your setup legal and roadworthy, no matter your destination.
CTO’s GVM solutions are:
Federally certified under Second Stage of Manufacture (SSM)
Compliant for pre-registration and post-registration
Accepted by all state and territory registration authorities including Queensland, Victoria, New South Wales, Western Australia, South Australia, Tasmania, ACT, and Northern Territory
Designed for integration with factory chassis and components
Each kit includes shock absorbers, coil springs, leaf packs, airbags, struts, and all required hardware, along with certification documents and installation instructions. Components are tested rigorously to ensure they handle Australian conditions with reliability and durability.
We supply heavy-duty GVM upgrades for:
RAM 1500, 2500, 3500 & TRX
Chevrolet Silverado 1500, 2500HD, LTZ, Trail Boss
Ford F-150, F-250, F-350 Super Duty
In addition to American trucks, we also support GVM upgrades for other popular models like:
Toyota LandCruiser, Hilux, Prado, Kakadu, VDJ
Ford Ranger Raptor, Mazda BT-50, Isuzu D-Max, Nissan Navara
Mitsubishi Triton, Volkswagen Amarok
Suzuki Jimny, MU-X, and more
Whether you’re touring with a roof-top tent, towing a heavy trailer, or carrying tools and gear for work, CTO has a load-carrying solution to suit.
Our kits are comprehensive, vehicle-specific, and tailored for high performance and compliance. Most kits feature:
Coil springs or parabolic leaf springs engineered for weight distribution
Heavy-duty shock absorbers and dampers
Torsion bar upgrades, bushes, control arms, and struts
Airbag suspension systems for load balancing
Brake boosters and pad upgrades where required
Chassis reinforcement if necessary
All legal documentation, certification papers, and installer instructions
These upgrades not only increase payload but also maintain ride comfort, handling, and braking performance across long-haul or rugged conditions.
Many customers pair their GVM upgrade with additional accessories that support increased loads, including:
Towbars, air compressors, and load-rated hitches
Bull bars, rear bars, and side rails
Canopies, drawers, roof racks, and storage systems
Suspension upgrades, lift kits, and shock absorber kits
Brake enhancements, wheel spacers, and driveline reinforcements
We stock high-quality brands including Dobinsons, Pedders, LoadRyder, Airbag Man, Lovells, and more.

RAM, Silverado & F-Truck GVM and Axle Upgrades | CTO Industries Australia
When it comes to touring, towing, or hauling serious loads, your RAM, Chevrolet Silverado, or Ford F-Truck needs more than just brute power—it needs federally-approved GVM upgrades and heavy-duty axle upgrades that deliver strength, safety, and compliance. At CTO Industries, we supply GVM and axle upgrade kits engineered specifically for large American utes and trucks, providing a complete solution from pre-registration compliance through to installation and certification.
Our kits are ideal for drivers pushing their vehicle to the limits—whether for touring Australia’s rugged tracks, building out a workhorse for mining or fleet use, or prepping a global overlanding rig with the load-carrying muscle to go further.
GVM (Gross Vehicle Mass) upgrades increase your truck’s legal weight-carrying capacity, while axle upgrades enhance load distribution, durability, and braking performance. Together, these systems allow your RAM, Silverado, or F-Truck to legally and safely carry the extra gear you need: drawers, rooftop tents, canopies, fridges, fuel cells, compressors, solar, recovery gear, and more.
Our axle and suspension upgrades include:
Leaf spring and coil spring enhancements
Dual-rate monotube shock absorbers
Heavy-duty arms, shackles, and mounts
Diff, brake, and driveline component upgrades
Underbody reinforcement and rear axle housing strengthening
Each kit is developed using components from trusted global brands like Ironman, Pedders, ARB, and Dobinsons, and complies with GVM-na and kg-heavy specifications for off-road, commercial, and touring vehicles.
CTO Industries supplies GVM upgrade kits tailored for:
RAM 1500, 2500, 3500, and TRX (up to kg-extra-heavy)
Chevrolet Silverado 1500, 2500HD, and Trail Boss
Ford F-150, F-250, F-350
Additional support for Hilux, LandCruiser, Ranger PXIII, Triton, D-Max, BT-50, Isuzu, Prado, and more
All GVM upgrades are:
Federally-approved for use in Australia
Available for pre-registration or post-registration certification
Compliant with Australian Design Rules (ADR)
Accompanied by full certification documents, weight reports, and engineering sign-off
Our upgrades are designed to help you legally handle greater payloads, tow with confidence, and ensure long-term performance without compromising warranty or safety.
Each GVM and axle upgrade package is engineered with heavy-duty components that improve load-carrying capability, stability, and braking response under pressure. Depending on your build and vehicle model, a typical kit may include:
Heavy-duty leaf springs or coils
Twin-tube or monotube shock absorbers
Upgraded shackles, brackets, and U-bolts
Extended brake lines and sensors
Bump stops, sway bar upgrades, and control arms
Diff breather kits and reinforced axles
Load-sharing airbags or secondary support systems
We offer packages with kg-medium-na, kg-heavy-na, and kg-extra-heavy ratings, depending on your required payload and axle load.
Upgrading your axles is essential when:
Fitting canopies, drawers, roof racks, or rooftop tents
Towing caravans, trailers, or boats beyond stock capacity
Building a touring setup with fridges, water tanks, solar, and camp furniture
Operating in mining, fleet, or remote-area work environments
Preparing for international overland travel
Our axle upgrades improve not just strength but vehicle stability, safety under braking, and load distribution—especially on uneven terrain or long-haul drives.
Our team can also advise on integrating your GVM upgrade with other touring essentials, including roof racks, drawers, solar panels, canopies, batteries, and communications equipment (e.g., UHF radios, antennas, pulleys, cell boosters).
Whether you’re heading off-grid or managing a fleet, we understand the demands of real-world usage. Our upgrade kits are commonly fitted alongside:
Alu-Cab and Ironman canopies
Camp kitchens, fridge freezers, and water tanks
Underbody protection, shocks, and drawers
Foam cell absorbers, snorkels, winches, and recovery gear
No matter where your RAM, Silverado or F-Truck is headed—from Cape York to the Simpson Desert, mining roads to remote station tracks—we help you upgrade with confidence.
