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 coil-over race spring is engineered for high-performance motorsports and competition suspension applications. Part number EIB0400.200.2600 represents Eibach’s proven Race Spring System, developed for consistent performance, precise suspension tuning, and dependable operation under demanding track conditions.\u003c\/p\u003e\u003cp\u003eEibach manufactures ERS springs in repeatable series production using extensive spring-making experience and strict quality control. This process helps deliver a highly linear spring rate with low manufacturing tolerances, allowing suspension builders and race teams to achieve predictable handling characteristics. The spring’s 4.00-inch free length, 2.00-inch inner diameter, and 2,600 lb\/in spring rate make it suitable for specialized coil-over suspension systems that require substantial wheel support and tuning flexibility.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eKey Product Specifications \u0026amp; Technical Data:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Eibach\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e EIB0400.200.2600\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Line:\u003c\/strong\u003e ERS Race Spring System\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Automotive coil-over and racing suspension systems\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFree Length:\u003c\/strong\u003e 4.00 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInner Diameter:\u003c\/strong\u003e 2.00 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpring Rate:\u003c\/strong\u003e 2,600 lb\/in\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpring Type:\u003c\/strong\u003e Linear-rate coil-over race spring\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eWhat's Included in the Box:\u003c\/strong\u003e One Eibach ERS coil-over race spring.
