More details

This new generation steel allows King Springs to further improve many of their existing designs by reducing the amount of steel required in a spring, making it substantially lighter (by approximately 30%) and reducing the solid height therefore increasing travel. Being of particular benefit at all top levels of Motorsport, this new high stress material was introduced to the leading v8 super car teams (inc HRT, FPR & HSV) in early 2007 giving a hugely successful endorsement of its characteristics & proven durability.

Although considerably expensive, King Springs have introduced this new high stress steel to their passenger car and 4wd designs which benefit the most at no extra cost to the consumer. As of now all King Springs manufactured coils are now in X5K material.

Manufacturing

King Springs are manufactured at our Head Office and Plant on Queensland's Gold Coast. Our large, modern factory complex, comprising of 3 buildings spanning 8,000 square metres, has been purpose built from the ground up. It includes computer controlled coiling machines, electronic furnaces, Automatic bar peeling process, and cambering machines which have been designed and custom built by King Springs to ensure all areas of our manufacturing process are of the highest standard.

The following is a brief step-by-step description
of our unique manufacturing process.

Only the finest high stress material from One Steel is used, shipped to the plant in an annealed state, then bar peeled and polished to the exact size to remove all surface defects and cut to length.

The material is heated in electric furnaces to 1000 degrees Celsius, formed on computer controlled machines and hardened by quenching in oil to achieve a hardness of 62 HRC.

The spring is then tempered by electronic controlled heat treatment to 500 degrees Celsius and hardness of 52 HRC.

Spring end grinding is applied if required.

Shot peening of the surface is completed to increase durability.

Every spring is solid scragged, tested and a full and final inspection is carried out.

All coil springs are powder coated for the most durable finish and offering maximum presentation.

The springs are finally labelled by inkjet, packed as pairs and ready for shipping. Large stocks are held for immediate supply.

All springs are manufactured under a quality system certified as complying with ISO-9001:2008.


Research and Development

The very heart of our business is the Research, Design and Development Department. It is responsible for the ongoing development and advancement of our product and encompasses all aspects of product evaluation.

At King Springs, we rely heavily on input not only from our staff members, but from the many specialist distributors throughout Australia that install our product daily. We regard qualified feedback as an extremely important part of our development program.

Exacting measurements are taken on and off the vehicle to thoroughly evaluate the design requirements.

Advanced equipment such as CAD systems and computer controlled testing machines are used to develop every part number. The spring is then extensively road tested to further fine tune and ensure optimum performance is gained.

Design Philosophy

At King Springs we're in the business of improving. We believe our product, in most cases, is purchased to achieve improvements in 3 major areas:

  • Height
  • Handling
  • Heavy Loading
