UMI Performance 64-66 GM A-Body Spring Kit: Lowering Excellence

Discover the ultimate in suspension performance with the UMI Performance 64-66 GM A-Body Spring Kit. This kit is designed to transform your classic GM A-Body vehicle, offering a comprehensive solution for lowering and enhancing your car's handling characteristics. Crafted with precision and quality, these springs are a game-changer for Auto-x and Pro-Tour applications, as well as for those who seek an aggressive cornering or cruising experience.
  • Expertly Designed: Engineered in collaboration with a leading Sprint Cup chassis engineer, these springs are the pinnacle of performance.
  • Quality Materials: Made from premium 5160 CrSi wire for the front and 9254 CrSi wire for the rear, ensuring durability and longevity.

Superior Specifications and Performance

The UMI Performance 64-66 GM A-Body Spring Kit boasts exceptional specifications that set it apart from the competition. The front springs offer a linear 530 lb/in rate, while the rear springs provide a linear 130 lb/in rate, ensuring consistent handling and responsiveness. This linear rate is crucial for maintaining stability during high-speed maneuvers and reducing body roll, which is particularly beneficial for Auto-x and Pro-Tour applications.
  • Engineered for Performance: The kit is designed for a 1” lowering, compatible with standard SBC, Pontiac 400, and aluminum head/intake Big Block Chevy, as well as LS power.
  • Customization Options: For lighter cars, spring trimming may be required, offering flexibility and adaptability to your specific vehicle needs.

Optimized for Versatile Applications

Whether you're an Auto-x enthusiast, a Pro-Tour competitor, or simply looking to enhance your daily driving experience, the UMI Performance 64-66 GM A-Body Spring Kit is the ideal choice. Its unique combination of lowering, increased stiffness, and linear rate provides a balanced ride that reduces body roll and prevents the "floating" feeling common in A-bodies.
  • Enhanced Handling: Experience improved cornering and stability, making your vehicle more responsive and enjoyable to drive.
  • Quality Assurance: UMI proudly manufactures these premium quality springs in the USA, ensuring the highest standards of craftsmanship and reliability.
