A coil spring is formed by winding wire spirally to create a series of stacked coils. Coil springs can take various forms, including compression, torsion, extension, or conical springs, all of which consist of helically wound wire coils. While there are many common calculations related to the physical dimensions of these coil springs, spring ...

— A coil spring provides support based on its diameter, the actual coil's diameter, how much elasticity the material has, how many active coils it has as well as the angle of the active coils. Less active coils increases the spring's resistance to compression. As the spring is compressed the furthest coils contact the wrapped ends.

— Progressive Rate Coil Springs deflect at different amounts per inch. An example would be: 300 lbs. = 1 inch deflection, 700 lbs. = 2 inch deflection, 1100 lbs. = 3 inch deflection, and so on. Progressive Rate Coil Springs have a soft initial spring rate, and a much firmer spring rate to handle more weight, decrease sway, and improve handling.

So let's look other ways to tell if the coil springs need replacing. There are 3 quick ways to tell if a coil spring needs replacing. The first will seem to be very obvious, the spring is broken. However with many coil springs the breakage occurs on the bottom coil and can not be detected unless the spring is removed from the vehicle.

— Compress the coil spring. Make sure that the coil compresses evenly, or you will stress the compressor and possibly break it. This would then release the incredible energy stored in the coil, possibly causing severe damage or personal injury. You should be able to move the spring around some, but not remove it yet.
