The new O-ring cutting tool for the Yokomo BD8 differentials. The tool allows to reduce the O-ring’s thickness to 1.5mm or 1.4mm in order to build a smooth and leak-free unit. Using the 1.5mm setting will create a smoother diff feeling than stock while the 1.4mm setting ensures an ever smoother diff action. The tool was developed for the original Yokomo BD-500G0 O-rings.
