See how KME Vehicle Engineering certified a RAM 3500 GVM upgrade to 6.2 tonnes under VSB 6, covering wheels, suspension, brakes, body mounting, fuel system, towbar/coupling and mass re-rating.

Aggregate Trailer Mass (ATM) is the maximum weight your caravan or trailer is allowed to be — fully loaded, on its own, disconnected from the tow vehicle — as set by the manufacturer.

Modifying a tow vehicle — through a GVM upgrade, a GCM upgrade, or heavier-duty suspension — can take it outside the specifications it was built and registered to. Without an engineer's certification, those modifications may not meet Australian Design Rules (ADRs), which can affect both roadworthiness and insurance outcomes. This guide explains what tow vehicle certification covers, when GVM, GCM, and ATM limits require an engineer's sign-off, and how the VSB14 and VSB6 codes

When Victoria Police conducted over 1,200 weighbridge operations in a single year, they discovered a startling reality: approximately 23% of vehicles failed to meet their legal weight requirements. If you've ever felt a pang of anxiety while passing a mobile weighing station, you aren't alone. Most...

A factual guide to GCM re-rating in Australia, including how GCM differs from GVM and towing capacity, the engineering evidence involved, and why approval requirements vary between jurisdictions.

Two common terms you might encounter are GVM and GCM. Both relate to vehicle weight limits but serve different purposes. Understanding these differences is crucial for safe driving, legal compliance, and vehicle performance. This guide breaks down what GVM vs GCM - how they differ, and why each matters.
