Product Details

Swift Springs Coilover Helper Springs (Flat Wire) in 25mm (1") ID and 5.3" length prevent your main coilover spring from dismounting the perch during droop travel using a flat wire design that provides minimal rate interference. These compact 25mm ID Swift flat wire helper springs keep the spring securely seated on the coilover perch under negative or zero load conditions.

The flat wire construction provides a compact profile and minimal rate contribution, making these ideal for tight-packaging coilover setups where every millimeter of clearance matters. Essential for applications where preloading the main spring creates ride height issues.

Why Use Swift Springs Helper Springs

  • Flat wire design for minimal rate interference and compact packaging
  • Prevents spring dismount during droop travel
  • Compact 25mm ID for small-bore coilover applications
  • 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 in pairs (set of 2).

    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.
