Do you already own BC Racing Coilovers and want to upgrade them to Swift Springs, or do you want to change your spring rates?

Swift Springs' innovative designs have made us a staple in the performance tuning world. Our products are the result of over 90 years of experience in industrial spring manufacturing. Our engineers have spent countless hours developing and re-developing our springs, in order to create a product that is light, durable, and compliant, while still maintaining linear spring rates.

Many enthusiasts will swap springs from brand to brand with the only noticeable difference being a stiffer or softer ride. But what if a spring could offer a noticeable increase in traction, smoother weight transfer, better ride quality, lower tire temperatures, and a more predictable feel? The engineers at Swift have taken that 'what if' and turned it into reality.

All Swift Springs are manufactured using (H5S.TW.) which is far superior to silicone chrome steel and allows us to wind our springs with less coils, resulting in reduced un-sprung weight and increased stroke.

Note: Includes a total of two (2) springs.

We highly recommend to shop by spring size instead of vehicle.

Additional Notes

  • All sales are final on this product. Please ensure you are selecting the right specs when customizing your coilovers.
  • It's highly recommended to ensure your struts are valved for the rates you are choosing. If you change the spring rates by 4k or more, it's also recommended to change the valving. Failure to properly pair your springs and struts can damage your coilovers, hinder performance, and reduce ride quality.
