About us

From Humble Beginnings

Our Story

IRONMAN 4X4 was founded in 1958 by Guenter Jacob

Our Journey Began in 1958

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 4×4 vehicles. JSW Parts soon became well known as a manufacturer and supplier of suspension parts all around the world.

Going Off-Road

In 1988 JSW Parts launched the IRONMAN 4X4 brand of springs and suspension parts in response to the increasing popularity of 4×4 vehicles, recognising 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 4×4’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.

Quality

Africa provides one of the most demanding testing grounds in the world – from rugged mountain passes and scorching deserts to muddy tracks and bustling city streets. Whether you’re tackling remote terrain on an overland journey or simply navigating the daily commute, IRONMAN 4X4 products are built to deliver outstanding quality and value for money.

Our reputation for strength and reliability is recognised not only by everyday adventurers but also by fleet operators and military organisations worldwide.
