At Feal Suspension we use only the best springs - genuine Japanese Swift springs. Use the charts below to determine which springs will suit your needs and fit your ride.
Swift's innovative designs have made us a staple in the performance tuning world. Swift products are the result of over 90 years of experience in industrial spring manufacturing. Swift engineers created 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.
Most of Swift 10" and longer springs (Excluding the Drag racing springs and Conventional springs) are barrel design; the design is to solve all spring Deflection (bowing) problems. With bowing springs, you can expect spring rate inconsistency, and rubbing against shock body that would lead to damage on the shock adjusting perch thread.
One approach to assess spring deflection would be to increase the number of coils on the springs. With more coils on the spring, you will experience less bowing motion. This is the easy and cheaper method to solve the issue. But the downside of this method is a decrease in spring stroke, increase in un-sprung mass, and will affect the overall movement of other suspension components
Swift Sport
Awesome ride comfort and tasteful drop. 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.
- Maintain or improve a smooth, comfortable ride.
- Increase handling by reducing body roll and squat in search of overall suspension balance.
- Lower the vehicle within tolerance of each vehicle's usable stroke.

Bump Rubber
Suspension usable stroke for the cars now a day is very limited compared to before. To let the suspension do its own job efficiently, many car manufactures use bump rubber as a part of a suspension's functional part, not only to limit the shock stroke but to prevent the shocks from bottoming out. This scenario also applies to real world racing, and we use this as a primary focus when designing the sport springs.
Vehicle characteristics
Swift developed each Sport Springs application based on the individual vehicle's unique characteristic. Put simply, a luxury car will maintain its luxury ride, and sports car will maintain its sports car feel.

Assist Springs
Get the best of both worlds, Swift assist springs provide a dynamic step linear rate. Like helper springs, the assist springs are designed to be fully compressed at static height. Every Swift assist spring compresses to the exact same height. This allows drivers to change assist springs without resetting the perch on the coilovers so the ride height isn't affected. Heavier rates of assist springs over helper springs are used to fine tune the rebound travel of the shock. These springs can also help preventing loss of traction due to inside wheel lift during hard cornering.
*Assist Spring comes with an adapter and 2 shims

Helper Springs
Helper springs prevent dismounting of springs from perch on coilover without changing spring rate.
Unlike assist springs, helper springs are specifically designed to have a minimal effect on the spring rate of the main coilover spring. Helper springs allow the spring to stay on mounted on the coilover perch when the shock is under negative or zero load, also known as droop travel. It is ideal to run helper springs on setups where you cannot preload the main spring due to height issues or when experiencing springs coming loose from the coilover perch.
