Factory GVM
Was Never
Enough.
Add a tray, canopy, toolboxes, drawers, rooftop gear, or hook up a caravan — and you're over GVM before you know it. The F-150's factory rating of 2,471kg GVM simply doesn't cut it for a properly built ute.
We build fully engineered GVM upgrade packages designed to dramatically increase your legal payload — without compromising safety, handling, or compliance. Every upgrade includes complete engineering paperwork for pre-registration federal approval.
- ✕Over GVM — every trip is technically illegal

GVM Upgrade
Frequently Asked Questions
Everything you need to know before you upgrade your F-150.
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.
If you already own a registered F-150, talk to our team about what options are available for your specific vehicle and state.
All F-150 GVM upgrade packages include a 4,500kg pre-registration braked towing capacity (except the 3.85T Stage 1 which starts from a lower base). If towing is a big part of how you use your F-150, make sure to discuss this with our team before choosing a package.
If you want to make changes after a GVM upgrade, the safest move is to check whether the new parts are covered by the original approval or whether the vehicle will need to be reassessed. Never assume you can swap components without confirming compliance first.
A professionally developed and fully documented upgrade gives you a far stronger position than a vehicle fitted with parts and no clear compliance pathway. Our SSM Federal Engineering certification provides the documentation you need for insurance and ATO purposes.
