Coil Springs

The primary function of springs, whether they be Leaf, Coil or Torsion Bar, is to absorb the shocks that are created when driving over irregular road surfaces and maintain correct downward pressure on the road for optimum tire/road surface contact.

The spring rate or stiffness must be matched to the weight of the car and the weight of the other suspension components. The handling of most vehicles is substantially improved by increasing the original spring rate to an optimum rate which maximises tyre adhesion while reducing body roll. All Pedders stores stock a wide range of springs to suit most popular vehicles. Your Pedders service technician can advise you on the replacement of original equipment and show you which springs will enhance your suspension system to level beyond manufacturers original standards.

Coil Springs are the foundations of the modern suspension system with most car manufacturers preferring Coil Springs due to their advantages of weight, tunability, space and ease of manufacture. Pedders research, design and manufacture their own range of Coil Springs from their own World-Class Manufacturing Plant in Victoria, Australia to QS9001 standards. Coil Spring design and manufacturing is a craft which requires strict adherance to a demanding series of procedures, all of which are critical to the performance of the final product. Pedders undertakes the following key steps in relation to its Coil Spring Manufacturing Process.

  • Hot coiling
  • Oil Quenching
  • Furnace Tempering
  • Shot Peening
  • Scragging
  • Loaded Height and Rate Testing
  • Powder Coating and Packaging


Located at Pedders Head Office, the Pedders Coil Spring Manufacturing Plant, holds the Quality Standard QS 9001. The goal for Quality System Requirements QS-9001 is the development of fundamental quality systems that provide for continuous improvement, emphasising defect prevention and the reduction of variation and waste in the supply chain. Pedders is the only aftermarket supplier of coil springs in Australia to hold this quality certification.

What this means for the retail and trade customers of Pedders is that they can be assured that they are using a product that is equivalent if not exceeding the quality required for suppliers of coil springs to OE manufacturers.

Quality springs for lowering your car or creating stronger suspension

Car springs absorb the shocks that are created when driving over uneven road surfaces. There is no high-quality 4x4 shock configuration without quality springs. They also maintain downward pressure on the road for optimum tyre/road surface contact. Don’t bounce around in your car and cause more damage to your chassis or suspension - to ensure that your springs are always at optimum level, get your parts checked out at Pedders.

Enhance your suspension system with Pedders springs
