UMI Performance 4049F Front Coil Spring Set for GM A-Body

The UMI Performance 4049F front coil spring set delivers modern handling and a crisp ride quality while maintaining your classic muscle car's factory appearance. Designed in collaboration with a leading Sprint Cup chassis engineer, these springs eliminate the common "floating" feeling associated with GM A-body vehicles.

Key Features:

• Linear 530 lb/in spring rate for consistent handling characteristics and reduced body roll
• Wound from premium 5160 Chrome Silicon wire for lasting durability and consistent performance
• Engineered ride height works with standard SBC, Pontiac 400, aluminum head/intake Big Block Chevy, and LS swaps
• Suitable for Pro-Tour, Auto-x, corner carving, and general street cruising applications
• Compatible with full-weight Big Block applications when quarter-inch nose-down rake is desired
• Durable black powder coat finish resists corrosion
• Proudly manufactured in the USA

The linear spring rate provides firm yet comfortable ride quality with predictable handling characteristics essential for performance driving. Premium materials ensure your vehicle sits properly for years to come. Note that lightened cars may require spring trimming for optimal ride height.
