Product Details
Swift Springs Coilover Helper Springs (Flat Wire) in 1.88" ID prevent your main coilover spring from dismounting the perch during droop travel, without adding meaningful spring rate to the stack. Unlike generic spacers or zip-tie solutions, Swift helper springs are precision-engineered to have a minimal effect on your main spring rate while keeping the spring securely seated on the coilover perch under negative or zero load conditions. These are essential for any coilover setup where preloading the main spring is not possible due to ride height constraints, or where the spring comes loose from the perch during full extension.
Why Use Swift Helper Springs
- Prevents spring dismount during droop travel without affecting main spring rate
- Precision-engineered flat wire design for minimal rate interference
- Essential for setups where preloading the main spring creates ride height issues
- Compatible with Swift metric and standard coilover springs
- Eliminates spring rattle and noise at full droop
- Swift Springs are made in Japan from high-quality spring steel
Note: Swift Helper Springs are sold in pairs (set of 2). Select your desired spring rate from the options above.
