Product Details

Swift Springs Standard Coilover Springs in 1.88" ID and 10" length are precision-engineered barrel-type race springs built to outperform conventional suspension springs in every measurable category. Designed for coilover dampers using standard SAE sizing, these 1.88" ID Swift springs are manufactured in Japan from proprietary H5S.TW high-tensile alloy steel. The barrel design eliminates spring deflection and bowing, preventing spring rate inconsistency and contact with the shock body that can damage adjusting perch threads. With fewer coils and reduced unsprung mass, Swift springs deliver increased traction, smoother weight transfer, lower tire temperatures, and the predictable feel that oval track, road course, drag, and off-road racers demand.

With over 90 years of spring manufacturing expertise, Swift Springs has engineered their standard coilover springs specifically for the American racing market. Unlike conventional springs where switching brands only changes ride stiffness, Swift Springs coilover springs deliver a noticeable increase in traction, smoother weight transfer, lower tire temperatures, and a more predictable feel that racers can tune around. Most Swift springs 10" and longer feature a barrel design that eliminates spring deflection and bowing — preventing spring rate inconsistency and rubbing against the shock body that can damage adjusting perch threads. All Swift Springs are manufactured using H5S.TW alloy, far superior to standard silicone chrome steel.

Swift Standard Coilover Spring Advantages

  • H5S.TW alloy steel outperforms standard silicone chrome in fatigue resistance and rate consistency
  • Fewer coils reduce unsprung weight and increase available shock stroke
  • Faster transient response tracks road surface changes for improved mechanical grip
  • Precision-engineered for oval track, road course, drag, and off-road racing
  • Consistent spring rates throughout the life of the spring
  • Made in Japan with over 90 years of spring manufacturing expertise
