{"product_id":"umi-performance-64-66-gm-a-body-1in-lowering-spring-set-rear","title":"UMI Performance 64-66 GM A-Body 1in Lowering Spring Set Rear","description":"A 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. These 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\/cruising. They have  a tough black powder coat finish and UMI proudly manufactures these premium  quality springs in the USA.","brand":"UMI Performance","offers":[{"title":"Default Title","offer_id":42519884988498,"sku":"UMI4052R","price":189.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0557\/4256\/2386\/files\/c6517965226ad1288bd3bc75ec8feb4a.jpg?v=1784782433","url":"https:\/\/www.vinniebuilt.net\/products\/umi-performance-64-66-gm-a-body-1in-lowering-spring-set-rear","provider":"VINNIEBUILT","version":"1.0","type":"link"}
