{"product_id":"umi-performance-4048r","title":"UMI Performance 64-66 GM A-Body Factory Height Springs Rear","description":"\u003cp\u003eA spring is a spring right? Wrong! When UMI  chose to manufacture our own line of springs we went all out. Designed in  conjunction with a leading Sprint Cup chassis engineer, these springs are the  best in the business. UMI’s springs are designed to add  modern handling and a crisp ride while maintaining the factory muscle car  appearance. The rear springs are wound from 9254 CrSi premium wire and feature  a linear 130 lb\/in rate. The linear rate provides consistent handling characteristics  which are important for Auto-x and Pro-Tour applications while the increase in  stiffness reduces body roll and prevents the “floating” feeling so common with  the A-body. These springs are suitable for Auto-x and Pro-Tour applications as  well as corner carving and general cruising.  They have a tough, black powder coat finish and UMI proudly  manufactures these premium quality springs in the USA.\u003c\/p\u003e\u003cp\u003eGenuine UMI Performance.
