Swift Spring Kits - Set of Four

Swift springs are manufactured with a unique spring compound "H5S.TW", which is stronger than silicon chrome. Its so resilient that it requires 2 rounds of shot peening in order to hold its coil shape and its so strong that it needs thinner wire compared to other manufactures. It also needs fewer coils, which greatly decreased weight while dramatically increasing available stroke. Springs are preset to reduce the sag experienced after installation and are given a 2-stage melamine coating providing an attractive layer of protection.

We can also order any combination of springs for your coil over setup. It's very simple to order Swift Springs for your vehicle. There are 3 options for the front and rear springs we need to order these: Spring Rate, Spring Length and Spring Inner Diameter. Conact us for price and availability.

 
Swift Lowering Springs

Swift Springs designed these suspension coil springs which are suitable for both street or track use. This complete set of front and rear suspension springs will work with the stock Mazda shocks. To noticeably improve the handling performance of your car, combine a set of Swift springs with a set of aftermarket Koni, or KYB performance shocks.
