The Eibach ERS 10.00 in. coil-over spring with a 3.75 in. inner diameter is specified for coil-over suspension setups where that ID and ten-inch length are required. Backed by Eibach's ERS lineage, it provides the spring element needed to adjust ride height and handling, offering consistent support for track or street coilover assemblies without requiring additional modification to the spring seating.
