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. Our front springs are wound from 5160 CrSi premium wire and feature a linear 530 lb\/in rate. 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\/cruising. The ride height is engineered for a 2” lowering with standard SBC, Pontiac 400 and aluminum head\/intake Big Block Chevy as well as LS power (lightened cars may require spring trimming). The front springs are also suitable for full weight Big Block applications when ¼” nose down rake is desired. 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\u003eFront Spring Rate\u003c\/strong\u003e: \u003cspan\u003e530\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":49954429206806,"sku":"GPHP-4051","price":309.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0930\/0878\/9782\/files\/0_5e351a42f4554ca4d60ef2734758d7c1_normalized.jpg?v=1776901906","url":"https:\/\/www.cspracing.com\/products\/umi-performance-4051-67-72-gm-a-body-spring-kit-2in-lowering","provider":"Complete Street Performance","version":"1.0","type":"link"}
