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 springs are wound from 5160 CrSi premium  wire and feature a linear 530 lb\/in rate. The 4050F’s are stiffer than stock to  provide increased performance with decreased body roll and a lower center of  gravity. 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, aluminum head and intake Big Block and Pontiac 400  as well as LS power (lightened cars may require spring trimming). The 4050F’s  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":49954440216854,"sku":"GPHP-4051F","price":169.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0930\/0878\/9782\/files\/0_63c19b25c9f260d13f13555b1d6b5669l_normalized_7e70ba11-e518-4a0c-b856-e65c0e2b56c0.jpg?v=1776962448","url":"https:\/\/www.cspracing.com\/products\/umi-performance-4051f-64-72-gm-a-body-2in-lowering-spring-set-front","provider":"Complete Street Performance","version":"1.0","type":"link"}
