As many may know, all springs are not created equal. Though they may carry similar diameters and spring rates, there is another factor many may not know. The manufacturing process and material play a crucial role in performance. Many years of experience, along with countless hours of research, Swift springs believes to have perfected the process. Putting this into action, Swift went to work with the goal of creating a new material. The culmination of hard work and determination, they created a proprietary steel alloy called "HS5.TW." This material accomplishes the primary goals Swift set out to accomplish which is as follows: 

  • The most consistent spring rate throughout the stroke
  • The largest amount of stroke
  • The highest durability against loss of spring height
  • The lightest in weight

Opening in 1997, Swift has dealt with a multitude of tasks and applications. From oval track and dirt racing, to the enthusiast street driver, Swift has gathered years of experience with world-class race teams and drivers around the world. With such a variety in demands over the years, you can rest assured knowing Swift will have the perfect spring to accomidate any need.
