The primary function of springs, wether 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 tyre/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
- Loaded Height and Rate Testing
- Powder Coating and Packaging
