The Eibach ERS 2.50 in. ID linear tender spring is a coilover replacement spring with a 2.50‑inch inner diameter and linear spring rate. Intended for coilover systems that need steady, repeatable deflection characteristics, it supports tuning ride height and spring stiffness while maintaining consistent behavior across repeated cycles typical of track and street use.
