Description

The Hyperco 18SN-400 delivers a stiff 400 lb/in spring rate in a compact 11-inch package, making it ideal for vehicles running aggressive suspension setups where space is limited. This conventional coil spring provides reliable support without the complexity of air springs or adjustable systems, allowing you to dial in your suspension geometry with confidence.
