CNC Cold Coil Springs

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 materials properties and resulting in longer life.

Bar Peeled

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.

Shot Peened

Manipulates material surface tension to reduce stress, greatly enhances spring life.

Triple Scragged

Each coil is fully compressed to a solid state 3 times to minimise coil settling.

Progressive & Linear Rate

Used in accordance with original vehicle manufacturers preference, progressive springs increase rate as the spring compresses, linear springs maintain a consistent rate throughout its range.

Power Coated

All springs are electro-static powder coated for a durable finish.
