Swift Coilover Springs from UpgradeMotoring.com

Swift 1.88 inch Inner Diameter - Straight Springs - Barrel Type - 10 inch Length

Swift specifically designed a standard measurement race springs to accommodate American race industries including oval track racing, and drag racing, and off road racing.

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 typical silicone chrome steel and allows us to wind a much more responsive spring 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

Unlike others, Swift designed barrel springs with ease and consistency of vehicle setup in mind, our barrel springs design have a maximum of 4" outer diameter (except B5 and B3 series). (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 especially with tight clearances to test and see which rates will fit and which rate does not. A heavier rate spring can interfere with the suspension A-arm or other suspension components.
