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.Barrel Design
Isn't the barrel design heavier? Not on Swift. Still one of the lightest!!
All of Swift Standard 10” and longer Coilover springs are barrel design; the design is to solve all spring bowing problems. With bowing springs, you can expect spring rate inconsistency, and rubbing against shock body that would lead to damages on the shock adjusting perch thread. (Except Swift Drag racing springs)
One approach would be to increase the number of coils on the springs. With more coils on the spring, you will experience less bowing motion. This is the easy and cheaper method to solve the issue. But the downside of this method is a decrease in suspension stroke, increase in un-sprung mass, and will effect the overall movement of other suspension components.
Unlike others, Swift designed barrel springs with one common rule, which is all the barrel springs design have a maximum of 4” OD. Because most other manufacture do not design their barrel springs with this rule. Most of their barrel springs outside diameter will differ from one rate to another. This creates a hard time for racers to test and see which rates will fit and which rate does not. A heavier rate spring tends to interfere with the suspension A-arm or other suspension components.
Generally speaking, the barrel designed springs tend to be heavier in weight than straight shape springs, but Swift coil springs will never have this problem because of our world leading coiling technology .
