SMART GVM Upgrades

GVM upgrade kits are well established in the Australian market, however through considerable customer feedback and research garnered over years of fitting suspension upgrades, we’ve learnt that many of the current GVM products are a compromise at best.

While they may be able to carry the required load, their ride, handling, height and other important factors all suffer as a result. It became clear that customers not only wanted the increase in load carrying capacity, but also:

• Optimal passenger comfort   • Minimum vehicle height  • Maximum vehicle handling

Durashock Suspension Systems took up the customer challenge. Following two years of exhaustive research, design and testing, we're proud to announce that the federally approved Durashock SMART GVM upgrade for Hilux Kun 26 4x4 , LandCruiser 200 series and LandCruiser VDJ 78/79 series is now available.

Durashock SMART GVM upgrades provide the largest federally approved gross vehicle mass upgrades for Toyota four-wheel drives. With model dependent increases of up to 600kg, there’s not a GVM upgrade on the market that can legally help your vehicle carry more.



High lifts when unladen are the norm with most GVM upgrade packages. However, these lifts alter the vehicle’s centre of gravity reducing its handling, performance and safety, and make it harder to load and unload. Durashock’s SMART GVM upgrades are specifically designed to minimise vehicle lift.
With unladen increases of just 20-25mm* in most instances, SMART GVM Upgrades sit lower, retain a lower centre of gravity and remain easier to load and unload than all other GVM upgrades on the market.


The extreme loads GVM upgrade packages are asked to shoulder require GVM coil and leaf springs to be heavier, stiffer and often larger than standard factory components, with the result being that they regularly provide harsh, unforgiving rides, particularly when the vehicle is driven unladen. Durashock SMART GVM upgrades have been purposely designed to deliver maximum load carrying capabilities, together with passenger friendly ride and handling characteristics, regardless of whether the vehicle is loaded or not.


Durashock SMART GVM’s class-leading load carrying capability, minimal height increase and all round comfort come together to create a GVM upgrade package that offers more real driver and occupational health & safety benefits than any other GVM product on the market. 
• Reduced chance of overloading    • Lower centre of gravity
• Reduced chance of rollover in emergency situations    •  Lower tray, door, tailgate and sill heights
• Reduced chance of manual handling injuries    • All round comfort   • Reduced driver stress and fatigue


Durashock SMART GVM upgrades are the only GVM upgrades tested and approved by the Federal Department of Transport and Road Safety Standards to feature SMART design. Under the terms of this approval, vehicle’s upgraded with SMART GVM upgrades are legally recognised as having undergone a SSM and so receive a second silver compliance plate (many GVM upgrade packages are classified as modifications). The insurance savings and legal advantages of owning and operating an ‘unmodified’ vehicle such as a SMART GVM equipped vehicle, makes Durashock SMART GVM upgrades the preferred choice of many large fleet and corporate customers.
