The company was founded in 1958  in Melbourne as a spare parts manufacturer called Jacob Spring Works (JSW). At the beginning of the 1980s, JSW Parts became specialized in supplying and designing of door wings and coil springs for motor vehicles, trucks, buses and off-road models and gained worldwide notoriety as a supplier of spare parts.
Due to the increasing popularity of off-road vehicles, the step was taken in 1988 to introduce the brand "IRONMAN 4x4" for springs and spare parts. Conventional suspensions were not up to the task of the company's extreme requirements.
In particular, the Ironman 4x4 suspension effortlessly handled the additional weight of front protection bars, winches and the increased demand for fuel.
Due to the extremely postive growth in the 4x4 market, the product portfolio was expanded in 2004. Off-road drivers were thus offered solution-oriented accessories such as winches, mountain equipment, safety bars, light and electronic aids.
