Ironman 4×4 produces 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 4×4 undergo class leading manufacturing processes to ensure the highest possible quality, including:
CNC COLD COILED
All Ironman 4×4 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 properties of the materials and resulting in longer life.
Bar peeling is the process of forming the material to an exact size before coiling. This ensures the diameter remains constant and free of flaws along its entire length.
Manipulates material surface tension to reduce stress, greatly enhances spring life.
Each coil is fully compressed to a solid-state 3 times to minimise coil settling.
PROGRESSIVE AND LINEAR RATE
Used in accordance to original vehicle manufacturers’ preference, progressive springs increase rate as the spring compresses, linear springs maintain a consistent rate throughout its range.
All springs are electro-static powder-coated for a durable finish.
