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.\u003cbr\u003e\u003cbr\u003e\u003cbr\u003e\u003cbr\u003e\u003cbr\u003eEPA Status: N\/A","brand":"UMI Performance","offers":[{"title":"Default Title","offer_id":53937386946878,"sku":"4051R","price":189.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0672\/8997\/3054\/files\/a2cbec62ffab3e2c0fd0648eeccc3349L_8e1f59fc-7e84-4613-8dbc-23f8ac0ff73c.jpg?v=1784676712","url":"https:\/\/stpaulspeed.com\/products\/umi-performance-64-72-gm-a-body-78-88-g-body-2in-lowering-spring-rear-4051r","provider":"St.Paul Speed \u0026 Performance","version":"1.0","type":"link"}
