Developed by ICON Vehicle Dynamics, this coil spring kit features a multi-rate design that provides compliant handling and improved comfort both on and off the trail.

Ideal for off-road enthusiasts and overlanders, this suspension upgrade enhances vehicle capability while maintaining ride comfort and handling stability under load.
