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\u003cdiv\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: \u003cspan\u003eBlack\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: \u003cspan\u003eBlack Powdercoated\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eSuspension Grade Type\u003c\/strong\u003e: \u003cspan\u003ePerformance\u003c\/span\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"UMI Performance","offers":[{"title":"Default Title","offer_id":49954438676758,"sku":"GPHP-4048R","price":186.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0930\/0878\/9782\/files\/0_1f521b20a292744114fe25af8371c7c2_normalized.jpg?v=1776962425","url":"https:\/\/www.cspracing.com\/products\/umi-performance-4048r-64-66-gm-a-body-factory-height-springs-rear","provider":"Complete Street Performance","version":"1.0","type":"link"}
