Swift Sport Springs keeps the quality ride you get from the showroom, and adds improved handling and lower ride height for driving enthusiasts and style minded drivers who demand only the best.

Swift did not develop the Sport Springs line by simply dropping the ride height. Unlike other manufacturers whose sole focus was style, Swift approached the creation of these lowering springs with 3 goals:

1) Maintain or improve a smooth, comfortable ride.
2) Increase handling by reducing body roll and squat in search of overall suspension balance.
3) Lower the vehicle within tolerance of each vehicle's usable stroke.

Most enthusiasts have had experiences with the typical harsh and uncomfortable ride from lowering springs. Performance is often overlooked by manufactures simply because it is easier to lower a vehicle for aesthetics. The end result is usually a bumpy ride that causes a decrease in traction, or excessive worn shocks caused by lowering the vehicle beyond the usable stroke.

As you can imagine, keeping or improving the comfort level while increasing performance is not an easy task, especially since these two aspects contrast with each other.

Where most of the competition simply gave in to the easier method, Swift Springs decided to tackle this issue by creating their own material (H5S.TW), and unique manufacturing method that works very well for this material. Working in unison, the material and manufacturing method provides a superior level for both comfort and handling.
