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. As  an industry leader in the muscle car suspension industry, UMI is proud to bring  you the best spring in the business. Consistent  rates and only the best materials (premium Chrome Silicon wire) ensure your car sits properly for years to come. Linear  spring rates (530 lb\/in front, 130 lb\/in rear) provides a firm yet comfortable  ride and incredible handling. No  more floating feeling. Suitable  for Pro-Tour, Auto-x and general cruising.\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\u003eRear Spring Rate\u003c\/strong\u003e: \u003cspan\u003e130\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":49954439954710,"sku":"GPHP-4050R","price":189.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0930\/0878\/9782\/files\/0_a2cbec62ffab3e2c0fd0648eeccc3349l_normalized.jpg?v=1776962443","url":"https:\/\/www.cspracing.com\/products\/umi-performance-4050r-64-72-gm-a-body-78-88-g-body-1in-lowering-spring-rear","provider":"Complete Street Performance","version":"1.0","type":"link"}
