GVM (Gross Vehicle Mass) suspension upgrades have become a major consideration for vehicle fleet operators and onsite contactors over the past decade.

This is due to safe operating legal load limits and insurance implications, for example, when a vehicle is involved in an accident or workplace incident.

All vehicles sold by dealerships are rated to a certain GVM, which determines the maximum payload that vehicle can legally carry.

There is a preference these days to fit out fleet and site vehicles with “trade mate” type bodies or site-specific body requirements in order to make vehicles “fit for purpose” for the environment or trade-related requirements they are operating in.

These bodies or trays are typically of a heavy-duty construction, fitted with electronics, dual wheel carries, dust proof seals, toolboxes, fridge compartments, toolboxes and water storage, etc. which are all very heavy.

This typically leaves very little available weight allowance left over for tools and materials before the vehicle is either at, or over, the legal load carrying capacity.

A GVM upgrade can effectively add around 500kg to a 3,500kg GVM on a 4WD vehicle, like the 79 Series Landcruiser.

This means the vehicle can be fitted out as required and carry the necessary payload required for the job, while still being within its legal GVM.

West Coast Suspensions is the trusted name in suspension since 1924.

West Coast Suspension (WCS) is one such company that has extensive experience in suspension replacement and modification, as well as holding Federal certification and approval to fit GVM upgrades as a Second Stage Manufacturer (SSM).

To achieve Federal certification and approval, WCS is required to submit relevant test data and documentation under the Australian Design Rules (ADR) categories to show that the vehicle can safely operate within vehicle safety guidelines, with the new upgraded GVM suspension.

These tests include laden & un-laden brake testing, Sine & Dwell testing for Electronic Stability Control (ESC), static brake or hand brake testing, lane change testing and Fine Element Analysis (FEA) of suspension components.

WCS delivers peace of mind to the fleet and end user, being one of the longest established and experienced after-market suspension modification companies in Australia.
