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.
King Springs leads the way in the design and manufacture of advanced progressive springs with both variable pitch and tapered wire forms. King Springs service all sectors of the automotive market including passenger, commercial and Four Wheel Drive vehicles and various Motorsport categories including circuit, rally, speedway and off-road racing.
