Description
A properly tuned rear spring is critical for maintaining chassis balance and controlling weight transfer during acceleration and braking. The Hyperco 18SNP11-225 delivers a 225 lb/in spring rate that’s engineered for rear-end applications where you need predictable compliance without excessive deflection. Whether you’re building a dedicated track car or fine-tuning a street performance setup, this conventional coil spring provides the foundation for responsive handling and improved traction.
Hyperco springs are manufactured to exacting tolerances and heat-treated to maintain consistent performance across thousands of cycles. The single pigtail design simplifies installation while reducing resonance frequencies that can cause audible noise and harshness transmission to the chassis.
