Eibach Race Springs are all manufactured in series production, often repeated, with a strong manufacturing experience. Thus, Eibach constantly achieves the most linear spring characteristic (rate) while maintaining the lowest tolerances and the highest quality in the industry.\n\u003cp\u003e\u003cstrong\u003eBrief Description:\u003c\/strong\u003e The Eibach ERS 4.00-Inch Length x 2.00-Inch ID Coil-Over Spring is a professional-grade race spring designed for coil-over suspension systems and demanding motorsport applications. Part number EIB0400.200.2400 delivers a 400 lb\/in spring rate for precise suspension tuning and consistent vehicle control.\u003c\/p\u003e\u003cp\u003eEibach ERS Race Springs are manufactured in repeatable series production using Eibach's extensive spring-manufacturing experience. This process helps provide a highly linear spring characteristic, tight rate tolerances, and dependable quality from spring to spring. The result is predictable suspension performance for racers, tuners, and performance enthusiasts who require accurate setup changes.\u003c\/p\u003e\u003cp\u003eThe compact coil-over format is suited to applications where spring rate, ride height, and suspension response must be carefully balanced. Its 2.00-inch inside diameter is intended for compatible coil-over hardware, while the 4.00-inch free length and 400 lb\/in rate support customized chassis setups. Verify the required spring dimensions, rate, and suspension compatibility before installation.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eProduct Specifications \u0026amp; Technical Data:\u003c\/strong\u003e\u003cbr\u003e\u003cstrong\u003eBrand:\u003c\/strong\u003e Eibach\u003cbr\u003e\u003cstrong\u003eProduct Line:\u003c\/strong\u003e ERS Race Spring System\u003cbr\u003e\u003cstrong\u003ePart Number:\u003c\/strong\u003e EIB0400.200.2400\u003cbr\u003e\u003cstrong\u003eSpring Type:\u003c\/strong\u003e Coil-over race spring\u003cbr\u003e\u003cstrong\u003eFree Length:\u003c\/strong\u003e 4.00 inches\u003cbr\u003e\u003cstrong\u003eInside Diameter:\u003c\/strong\u003e 2.00 inches\u003cbr\u003e\u003cstrong\u003eSpring Rate:\u003c\/strong\u003e 400 lb\/in\u003cbr\u003e\u003cstrong\u003eApplication:\u003c\/strong\u003e Automotive performance and motorsport suspension systems\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat's Included:\u003c\/strong\u003e One Eibach ERS coil-over spring.
