Carry More. Stay Legal. Tow Hard.

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.
- 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

Frequently Asked Questions
Everything you need to know before you upgrade your Ram 1500 DT.
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.
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.
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.
Our SSM Federal Engineering certification provides the documentation you need for insurance and ATO purposes.
