Swift Springs Swift Coil-Over Springs

These springs are parallel. Various ID.

Swift made a name for itself on the tracks of Asia, Europe, and U.S. by defying all accepted concepts and speculations about the future, if any, in coil spring science.
When many other company were looking at expensive and brittle titanium composites to create the next evolution of springs, Swift was looking at reinventing the entire science of coil spring dynamics. Swift saw that most others are using the old regular silicone chrome material, which was not strong enough. It used a heat tempering method that damaged the strength of the material that requiring more coils, in turn, more weight.
The material was also suffering from a short life span. With springs like this leading the industries, Swift saw room for improvement.

Swift's R & D team created material, called H5S.TW, which is stronger then regular silicone chrome material. Because of this material, we could make the spring wire thinner, and could wind the springs with fewer coils, which greatly decreased weight while dramatically increasing available stroke.

For better traction, smoother weight transfer, smoother ride, and easier set up!

Every spring manufacture use different method to rate their springs, causing frustration among many racers when they swap brands.
Brand A may test their spring rate at 1st 10% of the stroke while brand B may test at 60% of the stroke. By looking at the diagram below, you will get a clear picture of how this work.

As you can see, Swift springs are within 3% of the spring rate from 20-30% of the stroke all the way to about 80% of the stroke. (the average stroke range for most road race motorsports)
Swift tests the spring rate through the entire stroke to provide the best to the best.
