Founded in 1958 as Jacob Spring Works (JSW) in Melbourne, the company developed from the 1980s under the name JSW Parts into a specialist for door wings and coil springs for cars, trucks, buses and off-road vehicles. The introduction of the Ironman4x4 brand followed in 1988 due to the off-road boom to offer rugged suspensions and replacement parts. The resilient Ironman 4×4 suspensions easily handle demanding conditions and additional equipment. Genesis Import is the importer in German speaking regions.
