OPTION 1: 3999kg GVM Upgrade Package

79SC, 79DC, 76 & 78 SERIES

Engineered & federally approved GVM upgrade including SSM certification. Engineering support available for post registration engineering compliance with approved signatories.

GVM upgrade includes the fitting of compliant components including upgraded shock absorbers with a choice of the simplicity of the no nonsense Dobinsons IMS shock or the full adjustability of the remote reservoir MRA shock that can be tuned to handle the toughest roads. Paired with upgraded springs to handle the extra weight and an array of other components to improve both the ride and handling.
Package features lifts of between 40-75mm and wheel and tyre combinations up to 35” depending on your vehicles load and distribution. Some State and Territory restrictions apply to post registration lift height, wheel size and offset.

OPTION 2: 4499kg GVM Upgrade Package

79SC, 79DC, 76 & 78 SERIES

Engineered & federally approved GVM upgrade including SSM certification. Engineering support available for post registration engineering compliance with approved signatories.

Become “King of the Load” with DMW’s 4499kg GVM upgrade, featuring a replacement rear diff housing with chrome moly axles, increased rear axle load to 2900kg and track correction. Engineered & FEA derived chassis bracing added to give strength where needed and protect from chassis failure at those high stress points. To solve the 70 series lack lustre braking performance and to safely pull up that extra load we also install a full hydraulic brake booster, braided stainless brake lines and a handbrake upgrade. All these inclusions are standard on the 4499kg GVM along with upgraded shock absorbers with a choice of the simplicity of the no nonsense Dobinsons IMS shock or the full adjustability of the remote reservoir MRA shock that can be tuned to handle the toughest roads. Paired with upgraded springs to handle the extra weight and an array of other components to improve both the ride and handling.

Load rated wheels and tyres are required to meet the upgraded axle loads also. DMW have a number of great combinations available to personalise your ride and stay compliant.

The number one recommended modification to add to your 79 series dual cab to move the rear wheel position back to significantly improve the load carrying distribution and limit the amount of load behind the rear of the axle.

Carry more - Safely & Legally

The allowable payload on most modern 4WDs seems great on paper, but gets quickly used up when accessories, gear and passengers get loaded in. Remaining under the vehicles Gross Vehicle Mass (GVM) can seem almost impossible.

DMW is a recognised Second Stage Manufacturer (SSM) which allows us to develop and federally certify components to increase your vehicle's GVM.

This allows DMW or their authorised dealers to fit GVM kits for a variety of vehicles both Pre and Post Registration.

Maximise your allowable payload without risking your roadworthiness.

Each complete GVM kit has been extensively tested to ensure ADR compliance is maintained.

Safety and performance by design

Federal approval for GVM upgrades requires rigorous testing to ensure that the vehicle performs as well or better than when it left the original manufacturer. You can be sure that your DMW GVM upgraded 4WD will stop and handle well, even with the increased load on board.

Depending on the vehicle, the following testing is required:

Finite Element Analysis (FEA) testing: A check of the maximum load carrying capacity of the vehicle's axles, chassis or other critical components.
Brake Testing: Laden and Unladen brake testing as well as testing under partial system failure to comply with ADR35/00
ESC Testing: If required, this test ensures that the ESC system's response is the same or better than the original vehicle.

The GVM of any vehicle is the weight in kilograms that the manufacturer has specified as being the maximum that the vehicle can weigh when fully laden. DMW GVM upgrades allow a vehicle to be certified to carry a greater amount than the original manufacturer, without breaching applicable ADRs or laws. You can upgrade the GVM of a vehicle using either Federal approval or State based approval, depending on whether the vehicle has been registered or not.

• If the vehicle has never been registered, Federal approval can be applied. The DMW GVM kit comes complete with an additional compliance plate which will be fixed to the vehicle.

• If the vehicle is already registered, the data used in Federal compliance is used in conjunction with a vehicle inspection by an authorised State engineer to certify the vehicle.

The answer to this commonly asked question is no! This doesn’t matter if the GVM is done pre or post rego either, some installers will tell you otherwise but the fact is that GCM is a state based decision. Please see below exert from the Administrators circular 0-4-6 published 29/06/2018,

“As there are no ADRs that require the GCM of a light vehicle (ie a vehicle less than 4.5 tonnes Gross Vehicle Mass) to be certified by testing or evidence provided by a manufacturer, the Department does not assess, endorse or approve any purported change to a light vehicle’s GCM specification by a SSM.

It is also important to note that the Department does not restrict or prohibit GCM upgrades, as they are an in service matter that is the responsibility of state and territory registration authorities.”

Is my GCM automatically increased when a GVM upgrade is fitted?

*A vehicle that is legally registered in one Australian state of Territory with a BTC, GVM or GCM upgrade, can legally travel in another state or Territory.

** Please note that as of the Administrator Circular released in June 2018 BTC upgrades are not permitted on light vehicles. Please see exert below.

“The towing capacity of a light vehicle expressed as Gross Combination Mass (GCM) rating or Rated Towing Capacity or Maximum Braked Towing Mass rating must not exceed the value set by the first stage manufacturer. Second stage manufacturers are not permitted to increase the towing capacity as part of an SSM IPA that results in GVM upgrade,” it stated in Section 10.6, of the 0-4-6 circular issued in June 2018
