  • Engineered for High Performance and Long Service Life
    Each SuperSpring® has the optimum design, pitch, and metallurgical content for efficient performance. Rectangular wire springs are made from a trapezoidal cross section wire, which changes to a "D" cross section during coiling. This shape results in a lower maximum stress level, substantially contributing to longer spring life.
    Ready applies several advanced manufacturing processes to enhance the life of SuperSprings®. These include precision heat treating, shot peening to reduce mechanical stresses, and presetting by compressing to solid for increased set resistance and greatest resistance to fatigue.
  • Dependable Performance Is Quality-Assured
    SuperSprings® are manufactured exclusively from vacuum degassed, valve spring quality alloy steel. State-of-the-art equipment, including CNC coiling and grinding, is employed to achieve consistent dimensional accuracy within narrowest tolerances. Each production run is thoroughly inspected and documented to maintain strict quality. The result is a die spring of unsurpassed quality which many of the world's most demanding users specify for long, dependable performance.
