The Eibach ERS 1.88-inch ID coupling spacer is a suspension accessory sized for a 1.88" inner diameter, used in ERS coilover assemblies to set proper spacing between springs or components. It helps establish correct stack height and alignment for multi-spring or helper-spring configurations, allowing installers to achieve intended preload and geometry without modifying core springs. Use it where precise spacing is required in ERS systems.
