Description

A properly matched rear spring is critical to rear suspension geometry, weight transfer, and overall chassis balance—especially in racing applications where consistency lap-to-lap matters. The Hyperco 18SN-325 delivers a stiff 325 lb/in rate in a compact 11-inch package, making it ideal for vehicles requiring aggressive spring rates without excessive ride height loss. Whether you’re tuning a road course setup or dialing in a street performance build, this coil spring provides the predictable load curve and durability you need from a trusted manufacturer.
