Swift Springs Flat Wire Coilover Helper Spring Length ID kgf/mm

Swift Springs flat wire coilover helper springs, also called tender springs or helper coil springs, keep your main coilover spring seated on its perch when the suspension is unloaded or at full droop. They are built for coilover setups used in street, track, drift and motorsport applications.

Key Features:

• Minimal effect on ride rate: Swift designs helper springs to have very little influence on the spring rate of the main coilover spring. Swift's assist springs are a different product.
• Keeps the main spring seated: The spring takes up the empty travel when the damper is extended. This helps prevent the main spring from unseating or rattling under negative or zero load.
• Flat wire construction: The flat wire coil gives a compact stack height and a controlled, predictable compression stroke.
• Range of options: The line is offered in different spring rates, free lengths and inner diameters to suit different coilover setups.

Swift Springs is known for precision-wound racing and performance coil springs. These helper springs are a simple way to get quieter, more controlled suspension travel without changing the main spring rate. Check the specifications of each part number (length, inner diameter and spring rate in kgf/mm) to choose the right option for your coilover.
