UMI Performance 64-66 GM A-Body Spring Kit

The UMI Performance 64-66 GM A-Body Spring Kit is a game-changer for classic GM A-Bodies, offering an exceptional blend of modern handling and factory appearance. Designed in collaboration with a leading Sprint Cup chassis engineer, these springs are the epitome of quality and performance. Engineered to enhance both Auto-x and Pro-Tour applications, they provide a crisp ride while maintaining the iconic muscle car look.
  • Quality Materials: Crafted from premium 5160 CrSi wire for the front and 9254 CrSi wire for the rear, these springs are built to last.
  • Consistent Handling: The linear 530 lb/in rate for the front and 130 lb/in rate for the rear ensure stable and predictable handling characteristics.

Engineered Excellence

Experience the UMI difference with our high-quality springs. The front springs feature a 530 lb/in rate, while the rear springs offer a 130 lb/in rate, providing a linear response for optimal performance. This kit is engineered to reduce body roll and prevent the floating feeling common in A-bodies, making it perfect for Auto-x, Pro-Tour, corner carving, and general cruising. The ride height is designed to be level with standard engines like the SBC, Pontiac 400, and LS power, ensuring a balanced setup for various builds.
  • Engineered for Performance: These springs are tailored for drivers who demand exceptional handling and ride quality.
  • Customizable: Suitable for full weight Big Block applications with a desired ¼” nose down rake, allowing for a custom driving experience.

Perfect for Enthusiasts

The UMI Performance 64-66 GM A-Body Spring Kit is an ideal choice for enthusiasts looking to upgrade their classic muscle cars. Whether you're a competitor in Auto-x and Pro-Tour events or a weekend warrior, these springs offer the performance and stability you need. With a tough, black powder coat finish, they not only look great but also withstand the rigors of daily driving. Proudly manufactured in the USA, UMI stands behind the quality and performance of its products.
  • USA-Made Quality: Enjoy peace of mind knowing that these premium springs are crafted with pride in the United States.
  • Comprehensive Fitment: This kit is designed to fit a wide range of 1964-1966 GM A-Bodies, including Buick, Chevrolet, Oldsmobile, and Pontiac models.
