Swift’s R & D team has reinvented the science of coil spring dynamics using a resilient material stronger than regular silicone chrome material. The lighter and more sophisticated H5S.TW material allows springs to be coiled tighter with more effective stroke propensity yielding more impressive results. The combination of using H5S.TW and cold winding, results in the most linear springs on the market. Other manufacturers utilize hot winding that causes problems in durability, strength, and spring rate. Where the competition fails, Swift’s tests reveal that the caliber of its product are above and beyond with springs testing 3% of the spring rate from 20-80% of the stroke. Swift tests the spring rate through the entire stroke to provide the best to the best.
