UMI Performance 64-66 GM A-Body Factory Height Springs Rear

The UMI Performance 64-66 GM A-Body Factory Height Springs Rear are high-quality suspension components designed to enhance handling and ride quality for classic muscle cars.

Suitable for street, autocross, and Pro-Tour use, they are ideal for enthusiasts seeking improved corner carving and overall ride quality. Installation is straightforward as they are bolt-on replacements, maintaining factory height while delivering enhanced performance. These springs are compatible with factory suspension setups and are intended for use in vehicles aiming for improved handling dynamics without sacrificing the classic muscle car look.
