Eibach ERS extreme-travel barrel spring, 10-inch free length with a 2.5-inch inside diameter and XT barrel profile, made for coilover and suspension builds requiring extended stroke. The ERS form factor supports progressive compression behavior and packaging where a shorter compressed length or greater travel is needed, making it suitable for custom coilover applications.
