Swift Standard Race Springs
Less unsprung mass, more stroke, increased handling.
The only thing you will be loosing is track time.

As you might know, United States are the largest racer populated country in the world. Through our experiences from extensive testing in world class racing in Europe and Asia, we have great confidence that we can provide the same results in the US. Swift specifically designed a standard measurement race springs to accommodate American race industries including oval track racing, and drag racing.

By knowing the main characteristics that American racer demands, we designed and engineered the standard measurement springs based on data that we had collected through racers that are at the top of their sport. A slight difference in design then our metric coilover springs.
While most track racers have already began the ritual of swapping their springs, many swap from one brand to another let you notice the stiffness only as being either softer or harder. What if a spring could change other dynamics, such as a noticeably lighter unsprung mass, smoother weight transferring, better ride quality, lower tire temperature, and increased ability to anticipate vehicle reaction? Like most racers, Swift team hates to hear “what if”, so they built the “what if” into reality.



All of Swift Springs are made with our exclusive material
called H5S.TW.
Without this specially designed material, our light weight spring design would not exist.

All of Swift 10 or longer springs are barrel design; the design is to solve all spring bowing problems. With bowing springs, you can expect spring rate inconsistency, and rubbing against shock body that would lead to damages on the shock adjusting perch thread. (Except Swift Drag racing springs)

One approach 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 suspension stroke, increase in un-sprung mass, and will effect the overall movement of other suspension components.



Unlike others, Swift designed barrel springs with one common rule, which is all the barrel springs design have a maximum of 4” diameter.(Usually located on the center coil of the spring) Because most other manufacture do not design their barrel springs with this rule. Most of their barrel springs outside diameter will differ from one rate to another. This creates a hard time for racers to test and see which rates will fit and which rate does not. A heavier rate spring tends to interfere with the suspension A-arm or other suspension components.

Generally speaking, the barrel designed springs tend to be heavier in weight than straight shape springs, but Swift coil springs will never have this problem because of our world leading coiling technology .
