Australian designed parts of this quality and affordability will make a big impact on the NZ market. We can now offer solutions for users of 4 wheel drive vehicles, from farmers wanting to improve the ability of a vehicle to get around paddocks or back blocks, government departments and regional councils needing access to remote areas, to Kiwis enjoying hunting, fishing, camping or just exploring our great outdoors in their 4x4’s.

The majority of 4x4 vehicles in the current market are largely designed for on road use, we can now offer quality suspension and accessories at affordable prices, that will allow the off road ability of these vehicles to be greatly enhanced.

Ironman 4x4 products are designed in Australia and distributed throughout the world. Originally established in 1958, as a Melbourne based suspension parts manufacturer, named Jacob Spring Works. The company in 1982 took shape as JSW Parts, (short for Jacob Spring Works) to design and supply leaf and coil springs for cars, trucks, buses and 4x4 vehicles. JSW Parts soon became well known as a manufacturer and supplier of suspension parts all around the world.

In 1988 JSW Parts launched the Ironman 4x4 brand of springs and suspension parts in response to the increasing popularity of 4x4 vehicles, recognizing that standard suspension systems alone were not designed to cope with additional loads of bull bars, winches and extra fuel tanks.

Driven by explosive sales of 4x4’s, in 2004 the Ironman 4x4 range of products expanded quickly to meet the demand of off road users seeking solutions which would allow their vehicles to go off road loaded with accessories such as winches, recovery equipment, protective bars, canopies, lighting and electrical upgrades.

Today the vast continent of Australia serves as the perfect testing ground for Ironman 4x4 products, so whether crossing the outback in search of adventure or just driving the children to school in your local suburb, Ironman 4x4 can offer quality and value for money.

Many fleet and military organisations throughout the world have acknowledged the quality design and manufacture of Ironman 4x4 products. Together with these serious solutions, Ironman 4x4 products are also chosen the world over by offroad competition teams and drivers, and have successfully completed the Dakar Rally.
