Product Details

Swift Springs Coilover Helper Springs in 2.5" (65mm) ID and 5" length prevent your main coilover spring from dismounting the perch during droop travel, without adding meaningful spring rate to the stack. These compact 2.5" ID Swift helper springs are precision-engineered for imperial 2.5" coilover dampers, keeping the spring securely seated under negative or zero load conditions where preloading the main spring is not possible due to ride height constraints.

Unlike generic spacers or zip-tie solutions, Swift helper springs are designed to have minimal effect on your main spring rate. They are essential for any coilover setup where the spring comes loose from the perch during full extension, eliminating rattle and ensuring consistent suspension behavior.

Why Use Swift Springs Helper Springs

  • Prevents spring dismount during droop travel without affecting main spring rate
  • Compact 2.5" ID for imperial 2.5" coilover applications
  • Essential for setups where preloading creates ride height issues
  • Eliminates spring rattle and noise at full droop
  • Compatible with Swift metric and standard coilover springs
  • Made in Japan from high-quality spring steel

Note: Swift Helper Springs are sold individually (1 spring).

    Great springs

    Swift makes great springs. I haven't put these in yet, running different springs now.

    It's a matter of trial and error to get the car balanced.

    The picture is what is in the car now. The helpers are too soft so I bought assist springs as well.
