Yukon steel spool for GM and Chrysler 11.5-inch axles with 30 splines converts an open differential to full lockup, delivering constant traction to both wheels. It installs in place of the differential carrier assembly for a direct conversion and is made for heavy-duty use in off-road or racing environments. Not recommended for street-driven vehicles due to permanent lockup behavior.
