Hyperco 18SNU-150 Conventional Rear Coil Spring 16 Inch 5 Inch OD 150 lb/in Rate

The Hyperco 18SNU-150 is a high-performance conventional rear coil spring designed for motorsports racing applications. This SNU-Series spring features a 16-inch free length, 5-inch outer diameter, and a 150 lb/in spring rate, making it ideal for circle track racing and various competitive motorsports classes.

Dynamic Travel Response Technology:

This spring utilizes Hyperco's proprietary Dynamic Travel Response (DTR) enhancement, a breakthrough design concept that allows the spring to exceed performance requirements for travel and rate linearity while maintaining significantly less physical weight. This innovative technology provides superior performance on both dirt and pavement racing surfaces.

Key Features:

• High-tensile strength chrome silicone steel construction
• Blue powder coat finish for corrosion resistance and professional appearance
• Both ends closed and ground flat for proper seating
• 150 lb/in spring rate for precise suspension tuning
• 5-inch outer diameter fits standard racing hardware
• 16-inch free length designed for rear suspension applications
• Lightweight design maximizes performance without sacrificing strength
• Enhanced deflection capability for optimal suspension travel

Quality Assurance:

Each Hyperco spring undergoes rigorous quality control, including two separate magnaflux inspections—once before manufacturing and again after coiling. These inspections ensure the wire is free from surface imperfections that could lead to premature spring failure. The raw materials are sourced through mill-runs rather than standard inventory, allowing Hyperco to optimize wire specifications for racing applications.
