Coil Spring Technical Information Landrum Performance DESIGN:Most coil spring failure is directly related to the design of the spring. It is important to design the spring toits environment as well as its intended use. Pitch is the distance between the wires on any given coil-spring. Coil springs wound with an inconsistent pitch will produce an inconsistent rate.
These springs are easily identified by having a few closely wound coils at one end and then wider, equal spaced coils at the other end. They have rates described as 200/425lb/in. This means that the spring has an initial rate of 225lb/in through some range of deflection and then the rate transitions to 425lb/in through a deflection range of 1
