Ironman 4x4 produce a wide range of coil springs to suit a range of load ratings, all designed to maintain optimum ride height.
Coils springs produced by Ironman 4x4 undergo class leading manufacturing processes to ensure the highest possible quality, including:
CNC Cold Coiled
All Ironman 4x4 coil springs are CNC Cold coiled to ensure perfect consistency and accuracy. The result of cold coiling means that springs are subjected to less heat during the manufacturing process to help maintain the materials properties and resulting in longer life.
Bar Peeled
Coil spring steel is all bar peeled to ensure consistent material diameter before coiling. Bar peeling ensure exact material size is maintain and that it remains constant and free of flaws along the entire length of the steel used in the coils.
Shot Peened
Shot peening manipulates the spring materials surface tension to reduce stress and will enhance the springs life.
Triple Scragged
To minimize coil settling after installation, every Ironman 4x4 coil is fully compressed to a solid coil state three times.
Progressive and Linear Rate
Based off the original vehicle manufacturers preference accordance with the original vehicle setup. Progressive springs increase spring rate as the spring compresses, linear springs maintain a consistent rate throughout its range.
Powder Coated
All Ironman 4x4 coil springs are electro-static powder-coated for a gleaming and lasting appearance.
