SWIFT SPRINGS TAPERED COILOVER SPRING - SWS-18-080BP

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.

Swift designed barrel springs with ease and consistency of vehicle setup in mind, our barrel springs design have a maximum of 4" outer diameter (Usually located on the center coil of the spring) except B5 and B3 series. 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.

Bulletproof Series Springs (Parts number ending in BP)

Purpose built for those of you putting more stress on a spring than how is conventionally used. We sought after a new approach in development from our regular suspension spring.

After years of research and development, Swift springs would like to proudly present the BP Spring for circle track racing. Specifically designed to meet and surpass the unique needs of Circle Track Racers. Although specially made, these springs are constructed with the same SWIFT SPRINGS philosophy and that is to be responsive and increase overall traction. Bulletproof Springs from Swift Springs feature a copper colored coating.
