The Eibach ERS 3.00-inch ID isolator with a Delrin seat plate is built to provide a stable, quiet spring seat for ERS-style coilover assemblies sized to a 3.00" inner diameter. The Delrin seat plate cushions the spring-to-perch interface to limit noise and wear, helping ensure consistent spring positioning and smoother operation. It supports reliable spring seating and helps maintain suspension refinement in tuned or replacement coilover setups.
