{"product_id":"umi-performance-64-66-gm-a-body-factory-height-springs-rear","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","brand":"UMI Performance","offers":[{"title":"Default Title","offer_id":46648226447612,"sku":"4048R","price":278.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0641\/6518\/3740\/files\/1f521b20a292744114fe25af8371c7c2_e6323778-fbcd-4e39-a353-192fc2de90d5.jpg?v=1730824146","url":"https:\/\/diycustoms.store\/products\/umi-performance-64-66-gm-a-body-factory-height-springs-rear","provider":"diycustoms.store","version":"1.0","type":"link"}
