Variable Wire Diameter for Military Springs

Advantages of Variable Wire Diameter  vs. Constant Wire Diameter:

  • Up to 10% lighter based on a comparable spring design
  • Lower solid height than a conventional spring design
  • Less space required than a conventional spring design
  • Increased travel
  • Better fit and function with mating parts
  • Increased variable rate in a suspension application from softer to stronger as payload increases

Variable Wire Diameter Capabilities:

Wire Size:
0.75″ – 1.75″ starting bar size

Maximum Taper:
0.5″ each end

Maximum Taper Length:
12″ – 84″ from each end

Maximum Bar Length:
4.0′ – 21.0′
