UMI Performance Coil Spring Set for GM A-Body

UMI Performance coil springs are high-performance replacement suspension springs for classic GM A-Body muscle cars. They are designed to improve handling and ride quality, and they work as a direct bolt-on upgrade over tired, soft stock springs. Available in different ride-height options, they suit street cruising, Pro-Touring, autocross, corner carving and light drag use.

Key Features:

• Premium chrome silicon wire: The springs are built from chrome silicon (CrSi) spring wire, which resists sagging and keeps the car sitting properly for years.
• Linear spring rates: Consistent, predictable rates give the car repeatable handling characteristics. They also reduce body roll and remove the floating feel common to stock A-Body suspension.
• Race-informed engineering: UMI developed the springs with input from a top Sprint Cup chassis engineer.
• Durable powder-coat finish: A tough black powder coat protects the springs and gives them a clean, finished look.
• Made in the USA: UMI Performance designs and manufactures these springs in Pennsylvania.
• Direct bolt-on installation: No modifications are needed.

UMI builds these springs for enthusiasts who want modern handling and a crisp, controlled ride while keeping the classic look of their GM A-Body.
