ID Coil-Over Spring, 3200 lb\/in Rate","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 Spring is a professional-grade race spring designed for demanding motorsports and performance suspension applications. Part number EIB0400.225.3200 combines a 4.00-inch free length, 2.25-inch inside diameter, and 3,200 lb\/in spring rate for applications requiring exceptionally high suspension support and precise ride-height control.\u003c\/p\u003e\u003cp\u003eEibach ERS springs are produced in repeatable series production using advanced manufacturing processes and extensive spring-development experience. This approach helps deliver a highly linear spring characteristic, tight rate tolerances, and consistent performance across repeated use. The result is predictable suspension response for race vehicles, competition builds, and other specialized coil-over systems.\u003c\/p\u003e\u003cp\u003eBuilt for compatibility with 2.25-inch coil-over platforms, this automotive spring is suited to properly matched dampers, sleeves, and suspension components. Professional installation and suspension setup are recommended to confirm spring clearance, installed height, preload, and damper compatibility. The package includes one Eibach ERS coil-over race spring.\u003c\/p\u003e\u003ch3\u003eKey Product Specifications and Technical Data\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eBrand: Eibach\u003c\/li\u003e\n\u003cli\u003eProduct Line: ERS Race Spring System\u003c\/li\u003e\n\u003cli\u003ePart Number: EIB0400.225.3200\u003c\/li\u003e\n\u003cli\u003eApplication Type: Automotive coil-over suspension\u003c\/li\u003e\n\u003cli\u003eFree Length: 4.00 inches\u003c\/li\u003e\n\u003cli\u003eInside Diameter: 2.25 inches\u003c\/li\u003e\n\u003cli\u003eSpring Rate: 3,200 lb\/in\u003c\/li\u003e\n\u003cli\u003eSpring Type: Linear-rate coil-over race spring\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eWhat's Included\u003c\/h3\u003e\u003cp\u003eOne Eibach ERS coil-over race spring.
