The Problem

Factory GVM
Wasn't Built
For This.

The Ram 1500 DT is one of the most capable trucks on Australian roads — but the factory GVM rating simply wasn't designed with a serious touring or work build in mind. Add a tray, canopy, toolboxes, drawers, a heavy touring setup, or hook up a van and you're over legal GVM before you know it.

We build fully engineered GVM upgrade packages that dramatically increase your legal payload capacity — without compromising safety, handling, or compliance. Every upgrade includes complete engineering paperwork for pre-registration federal approval. ASV imports only.

⚠ Building your Ram 1500? You're almost certainly going to be overweight
  • Over GVM — every trip is technically illegal
  • Unsafe under braking with a full touring load
  • At risk of insurance void in an accident
  • Non-compliant for ATO tax deduction
  • Factory towing limits become your hard ceiling

Being over weight isn't rare.
It's most builds.
Fix yours properly.

America's Garage GVM Upgrades for the Ram 1500 DT are federally approved for pre-registration — backed by SSM Federal Engineering and installed by vetted workshops nationwide. ASV imports only.

FAQ — Ram 1500 DT GVM Upgrade | America's Garage

GVM Upgrade
Frequently Asked Questions

Everything you need to know before you upgrade your Ram 1500 DT.

The Ram 1500 DT's factory GVM rating doesn't account for the weight of a typical Australian touring or work build. Add a tray, canopy, toolboxes, drawers, roof rack, camping gear, and factor in passengers and fuel — and you can exceed the factory GVM before you've even hitched up a trailer. A GVM upgrade legally increases the weight your Ram can carry, so you stay compliant on every trip.
GVM (Gross Vehicle Mass) is the maximum legal weight of your Ram 1500 fully loaded — including the vehicle, passengers, fuel, accessories, tray, canopy, drawers, tow ball download, and everything else on the vehicle.

GCM (Gross Combination Mass) is the maximum legal weight of the vehicle and trailer combined.

In simple terms: GVM is about what your truck can carry on its own wheels, while GCM is about how much total weight the truck and trailer can handle together.
Yes — all Ram 1500 DT GVM upgrade packages from America's Garage are designed and certified for ASV (Ateco Special Vehicles) imports only. This refers to the Ram 1500 DT sold through the official Australian ASV distribution channel, which is the most common variant in Australia. If you're unsure whether your Ram qualifies, contact our team and we'll confirm before you book.
The Ram 1500 DT is available with a V8 engine or the Hurricane inline-six engine (Laramie variant). Due to differences in platform weight, the GVM upgrade tiers differ between these variants — V8 models are upgraded to 3.65T or 3.85T, while Hurricane Laramie variants are upgraded to 3.99T.

The Hurricane-specific 3.99T packages are engineered specifically for that platform and use the same Fox 2.5" shock lineup, UCAs, and airbag support.
Not automatically. A GVM upgrade increases how much weight the vehicle can legally carry on its own wheels — not necessarily how much it can tow. Towing capacity, tow ball download, axle loads, and GCM all interact with each other.

All Ram 1500 DT GVM upgrade packages include a 4,500kg pre-registration braked towing capacity. If towing is a big part of how you use your Ram, make sure to discuss this with our team before choosing a package.
A GVM upgrade can affect warranty, insurance, and servicing depending on the vehicle, the parts used, and whether the upgrade has been correctly approved and certified. The best way to protect yourself is to use a properly supported GVM upgrade program, keep all paperwork, and make sure the vehicle is modified and certified correctly.

Our SSM Federal Engineering certification provides the documentation you need for insurance and ATO purposes.
