Kings Springs - Coil springs

Kings Springs exclusively use high quality, high stress X5K spring steel.

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.

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.
