UMI Performance 4049R Rear Coil Spring Set for GM A-Body

The UMI Performance 4049R rear coil spring set is engineered to transform your classic GM A-Body muscle car with modern handling performance while maintaining its factory appearance. Designed in collaboration with a leading Sprint Cup chassis engineer, these springs eliminate the floating sensation common in vintage A-Body vehicles and deliver precise, predictable handling.

Key Features:

• Linear 130 lb/in spring rate for consistent handling and a firm yet comfortable ride
• Wound from premium 9254 Chrome Silicon (CrSi) wire for superior durability and longevity
• Reduces body roll and improves cornering stability
• Ideal for Pro-Touring, autocross, and spirited street driving
• Durable black powder coat finish resists corrosion
• Maintains factory ride height and classic muscle car stance
• Proudly manufactured in the USA

These springs are specifically designed for enthusiasts who demand modern performance without compromising the authentic look of their classic A-Body. The linear spring rate ensures consistent handling characteristics crucial for competitive autocross and Pro-Touring applications, while the increased stiffness eliminates the soft, wallowing ride quality of stock springs. Whether you're carving corners on a road course or enjoying a weekend cruise, the UMI 4049R spring set delivers the perfect balance of performance and comfort.
