ID Coil-Over Race Spring, 350 lb\/in","description":"Eibach's ERS line has evolved over the years to be the world's most prominent, comprehensive and superior Race Spring System. 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 coil-over race spring is engineered for serious motorsports and performance suspension applications. Part number EIB0400.200.0350 features a 350 lb\/in spring rate and is designed to deliver consistent, predictable suspension performance under demanding driving conditions. The 4.00-inch spring length and 2.00-inch inside diameter make it suitable for compatible coil-over and racing suspension systems.\u003c\/p\u003e\u003cp\u003eEibach manufactures ERS springs in repeatable series production using extensive spring-design and manufacturing expertise. This approach helps provide a highly linear spring characteristic, tight rate tolerances, and dependable quality from one spring to the next. The result is precise suspension tuning, improved vehicle balance, and consistent handling response during competition or high-performance driving.\u003c\/p\u003e\u003cp\u003eBuilt for applications where accurate spring behavior matters, the Eibach ERS spring supports customized suspension setup and corner-weight tuning. Verify the required spring rate, free length, inside diameter, and suspension compatibility before installation. This automotive race spring is intended for use with compatible coil-over hardware and should be installed by a qualified professional.\u003c\/p\u003e\u003ch3\u003eWhat's Included\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eOne Eibach ERS coil-over race spring\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eUniversal motorsports fitment for compatible coil-over suspension systems.
