The primary function of springs, whether they be Leaf, Coil or Torsion Bars, is to absorb the shocks that are created when driving across irregular road surfaces and to maintain the tyres contact with the road.
The spring rate, or stiffness, must be matched to the weight of the vehicle resting on it and the weight of the other suspension components and the wheel. Spring rate also controls roll stiffness, or body roll. By reducing the amount of body roll, we reduce the amount of wheel camber change. Large camber change can drastically reduce the tyres contact with the road surface, severely limiting the handling potential during cornering.
The handling of most vehicles is substantially improved by increasing the original spring rate to an optimum rate which maximises tyre adhesion and reduces body roll for better handling. Increasing the spring rate beyond the optimum rate detracts from the handling potential as the tyres begin to skip over bumps, reducing grip and safety.
Coil Spring Design and manufacturing is a craft which requires strict adherence 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
Circulated Oil Quenching
Furnace Tempering
Shot Peening
Scragging
Loaded Height and Rate Testing 2mm Tolerance
Powder Coating and Packaging
Pedders offers to its trade and retail customers four different branded coils spring ranges. These are as follows:
* Pedders Heavy Duty Coil Springs (standard and raised height replacement coil springs for passenger and light commercial vehicles)
* Pedders SportsRyder Coil Springs (premium range of lowered coil springs for sports and performance applications)
* Pedders Touring Springs are built to industry standards (thus less than Pedders premium SportsRyder range) and priced for the performance motorist on a budget.
* Pedders Trak Ryder Coils Springs (four wheel drive coil springs available in several height options for a variety of applications.)
