It is important to remember that a spring supports weight and sets the vehicle ride height.

It determines the optimum limits of the suspension travel and and is a major contributor to the vehicle's ride and handling.

But a spring cannot operate effectively without a correctly matched shock absorber.


  1. Military Wrap.
    Where possible, a military wrap is used as a safety mechanism to aid the vehicle's steering in case of the main leaf breaking
  2. Drawn, Tapered and Diamond Cut Leaves.
    To assist in Load Distribution and reduce Inter Leaf Friction which occurs at the end of the leaves.
  3. Design Characteristics.
    All leaf lengths are designed and calculated to achieve a High Performance Spring. Inappropriate leaf lengths will concentrate
    stress in one particular area and will cause premature sagging or breaking.
  4. Scrag Testing.
    Is a process that is done to most of the springs manufactured.  The Springs are scragged to 90% of the yield stress of the material
    used, to help eliminate sagging. Scragging is a process whereby the spring is load tested to be straight or reversed curvature
    to relieve and prevent sag.
  5. Inter Leaf Anti-Friction Liners.
    Reduce friction at the tip of the leaves where the load is the greatest in the spring.
  6. Quality Control.
    Stringent quality control procedures for Heat Treatment (Tempering) processes at all phases of the manufacturing processes ensures Dobinson Springs are made the same exceptional way every time.
