the v2 damper rod for the icon and eclipse 4 has a much larger internal hole diameter. it replaces the u8088. this could simply be seen as a weight reduction over the v1 however its primary purpose is to allow for easier filling with damping oil. a larger quantity of oil can be used leading to a much longer lasting consistent damping and therefore less frequent maintenance is required. the damping rate when freshly filled remains unchanged and damping setup?s will carry over from the v1 rod.
