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 0400.225.1250 is a professional-grade coil-over race spring engineered for consistent performance in demanding motorsports applications. Designed with a 4.00-inch free length, 2.25-inch inside diameter, and 1,250 lb\/in spring rate, this spring supports precise suspension tuning where predictable response and repeatable handling are essential.\u003c\/p\u003e\u003cp\u003eEibach ERS springs are manufactured in series production using tightly controlled processes and extensive spring-manufacturing expertise. This approach helps deliver a highly linear spring characteristic, low production tolerances, and dependable quality from spring to spring. The result is a race spring that allows suspension builders and drivers to make accurate setup changes with confidence.\u003c\/p\u003e\u003cp\u003eBuilt for compatible coil-over suspension systems, the Eibach ERS race spring is suited to competition vehicles and performance-focused applications requiring a high spring rate. Its compact coil-over format makes it a practical choice for custom suspension tuning, while the clearly defined rate supports repeatable setup development. Verify spring diameter, free length, rate, and suspension compatibility before installation.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat's Included:\u003c\/strong\u003e One Eibach ERS coil-over race spring.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFitment:\u003c\/strong\u003e Universal motorsports and custom coil-over applications when the specified spring dimensions and rate match the suspension system.
