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\u003eThe Eibach ERS 0500.225.2100 is a professional-grade coil-over race spring engineered for high-performance motorsports and competition applications. As part of Eibach’s renowned ERS Race Spring System, it delivers consistent spring behavior, precise load control, and dependable performance under demanding track conditions. The spring is designed for coil-over suspension systems using a 2.25-inch inside diameter and provides a 2100-pound-per-inch spring rate.\u003c\/p\u003e\u003cp\u003eEibach manufactures ERS springs in repeatable series production using extensive spring-development experience and strict quality controls. This process helps maintain a highly linear spring characteristic, low manufacturing tolerances, and consistent performance from one spring to the next. The result is more predictable suspension response, improved tuning accuracy, and reliable support for race teams and performance enthusiasts who require precise chassis control.\u003c\/p\u003e\u003cp\u003eThe Eibach ERS 0500.225.2100 is suitable for custom suspension setups where spring rate selection is critical to vehicle balance, ride-height control, and handling performance. Confirm spring-rate requirements, available travel, installed height, and coil-over compatibility before installation. This product is intended for automotive racing and performance suspension use; vehicle-specific fitment may vary based on the coil-over hardware and suspension configuration.\u003c\/p\u003e\u003ch3\u003eProduct Specifications and Technical Data\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eBrand: Eibach\u003c\/li\u003e\n\u003cli\u003ePart Number: 0500.225.2100\u003c\/li\u003e\n\u003cli\u003eProduct Family: ERS Race Spring System\u003c\/li\u003e\n\u003cli\u003eApplication Type: Coil-over suspension race spring\u003c\/li\u003e\n\u003cli\u003eSpring Rate: 2100 lb\/in\u003c\/li\u003e\n\u003cli\u003eFree Length: 5.00 inches\u003c\/li\u003e\n\u003cli\u003eInside Diameter: 2.25 inches\u003c\/li\u003e\n\u003cli\u003eProduct Type: Automotive suspension component\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eWhat’s Included\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eOne Eibach ERS coil-over race spring\u003c\/li\u003e\u003c\/ul\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eProfessional race spring: Developed for demanding motorsports and high-performance coil-over suspension applications.\u003c\/li\u003e\n\u003cli\u003eConsistent spring rate: Series production helps deliver repeatable performance and predictable suspension response.\u003c\/li\u003e\n\u003cli\u003eLinear spring characteristic: Engineered to provide controlled, consistent load behavior throughout the working range.\u003c\/li\u003e\n\u003cli\u003ePrecision manufacturing: Low production tolerances and Eibach quality standards support accurate suspension tuning.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cstyle\u003etable.productattributes, .productattributes td { border-bottom: 1px solid #ddd; border-collapse: collapse; padding: 2px; text-align: left; }\u003c\/style\u003e\n\u003ctable class=\"productattributes\"\u003e\n\u003cthead\u003e\u003ctr\u003e\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\u003ctd\u003eAir Freight Prohibited: false\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eNot Carb Approved: false\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eLtl Freight Required: false\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eProp 65: Unknown\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003ePart Type: automotive\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eEpa: N\/A\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eCarb Acknowledgement Required: false\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eRegular Stock: false\u003c\/td\u003e\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003cbr\u003e","brand":"Eibach","offers":[{"title":"Default Title","offer_id":67581664723196,"sku":"0500.225.2100","price":110.9,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0641\/6518\/3740\/files\/c24c7ce5c049c03c6a9b0b46035ed1bd_2e177664-70d7-4255-a542-1832469b3459.jpg?v=1790408919","url":"https:\/\/diycustoms.store\/products\/eibach-ers-5-00-inch-length-x-2-25-inch-id-coil-over-race-spring-2100-lb-in","provider":"diycustoms.store","version":"1.0","type":"link"}
