Ruggedness Built-In

Australian conditions are some of the harshest in the world, and Durashock products have endured rigorous in-house and off-road testing to make sure they comply with our exacting standards. The entire range has been designed to perform better for longer, even in the hostile conditions of the Australian outback.

We are confident Durashock suspension components can stand up to any environment you want to tackle, so you can take your vehicles wherever they need to go.

Custom-designed for Heavy Use

Driveline works closely with a number of recreational, fleet and Australian mine operators to create a range of high quality and cost-effective 4WD suspension components for these markets. Vehicles operating in these industries frequently face gruelling conditions, requiring suspension components that not only withstand these punishing environments, but conquer them. Our custom 4WD suspension components, GVM Upgrades and 4×4 kits are designed specifically for heavy duty use, constantly performing through the intense pressure and rigorous grind that these work environments are known for.

After all, when you’re working in some of the most demanding industries in the world, you need 4×4 suspension components that can take the pressure and push back. You need Durashock.

Our SMART System

Properly increasing your vehicle’s gross vehicle mass (GVM) is notoriously difficult. Throughout our 30+ years in the Australian automotive industry, we’ve noticed that most upgrades tend to be compromises rather than actual solutions. When it comes to increasing your vehicle’s load potential, most typical upgrades provide it at the expense of safety and performance. To us, this is simply unacceptable.

That’s why we set out to design and create our own line of GVM upgrades and shock absorbers. From the beginning, we were committed to producing an upgrade that was different from the rest of the market. And that’s exactly what we created, thanks to Durashock’s SMART System leading our design. SMARTS stands for:

Safely increasing your Gross Vehicle Mass (GVM) is a difficult task. Many existing upgrade kits come with compromises that may prove dangerous in the wrong circumstances. Driveline’s SMART GVM Upgrade kits solve this problem by providing a safe, effective and reliable system for increasing your load capacity without affecting vehicle performance or safety.

Depending on your make and model, our SMART GVM kits could provide as much as a hefty 600kg increase in load capacity while staying within legal limits.

Increasing your GVM with a minimal increase to your suspension height improves the handling, performance and safety of your vehicle. Our SMART GVM kits can greatly increase your carrying capacity with just a 25-50mm height increase for most makes and models.

Many kits increase GVM by using uncomfortably stiff springs or hard suspension components. Our Durashock GVM Upgrade kits are designed to increase your vehicle capacity without sacrificing a smooth and friendly ride, even when the car is unladen.

Our GVM Upgrade kits improve your load capacity without increasing the height or ruining the ride, and this equals real safety benefits. Modified suspension changes the way your vehicle handles, and high lifts or stiff springs can create serious health and safety risks. Durashock SMART GVM Upgrades are designed to reduce these factors, making our kits some of the safest on the market.

Durashock SMART GVM Upgrades are the only GVM upgrades tested and approved by the Australian Department of Transport and Road Safety Standards to feature SMART design.


When it comes to function and performance, no other 4WD suspension and GVM upgrade can compete with Durashock. The following are the reasons why Durashock’s S.M.A.R.T System makes it the best shock absorbers available on the market:
