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. Our front springs are wound from 5160 CrSi premium wire and feature  a linear 530 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. The ride height is engineered to  be level 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 \" 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\u003cp\u003eThis product may expose you to chemicals known to the State of California to cause cancer, birth defects, or other reproductive harm.\u003c\/p\u003e","brand":"UMI PERFORMANCE","offers":[{"title":"Default Title","offer_id":51782094979384,"sku":"U01C 4049F","price":175.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/horsepower-asset-338569-5839169-square_342c94d0-51cf-4b7d-bde5-a7d692e0d994.webp?v=1778277965","url":"https:\/\/store.motormia.co\/products\/umi-performance-64-72-gm-a-body-factory-height-springs-front","provider":"MOTORMIA","version":"1.0","type":"link"}
