Product Details

Swift Springs Standard Conventional Springs in 5" OD and 20" length are purpose-built for competitive oval track, stock car, and circle track racing applications. These 5" OD Swift race springs are manufactured in Japan from proprietary H5S.TW high-tensile alloy steel, delivering measurably better traction, weight transfer, and tire temperature consistency compared to standard silicone chrome springs. With fewer coils and optimized winding, Swift conventional springs reduce unsprung mass and provide faster transient response, giving drivers a more predictable car through every phase of the corner.

Swift Springs has over 90 years of precision spring manufacturing experience, and their conventional race springs are specifically engineered for American oval track and circle track racing. Swift conventional springs deliver a noticeable performance difference over standard springs — providing increased traction, smoother weight transfer, lower tire temperatures, and a more predictable car through every phase of the corner. Bulletproof Series springs (part numbers ending in BP) are purpose-built for applications that put more stress on a spring than conventional use, developed specifically to meet the unique demands of circle track racers.
