Eibach ERS barrel spring, 12in length with a 2.50in internal diameter and 3.23in block height, intended for coilover or shock applications where a compact barrel‑type coil is required. These springs serve as replacement or upgrade components in suspension builds that use measured spring dimensions for correct fitment, allowing tuners and installers to match spring geometry to their shock or coilover assembly specifications.
