Description
If you’re tuning your rear suspension geometry or building a custom chassis, spring rate directly impacts your vehicle’s handling balance and load transfer characteristics. The Hyperco 18SN-125 delivers a moderate 125 lb/in rate ideal for street-driven performance builds and amateur road course applications where you need predictable compliance without excessive harshness. Precision-wound and backed by decades of racing heritage, this rear spring integrates seamlessly into most independent rear suspension designs.
