Do you regularly participate in track events or think it's silly to waste your entire day at the dealership for a simple transmission or differential fluid change?  We say DIY!  This 13mm square socket was discovered by one of our own employees a few years ago.  He absolutely swears by it!  Imported from Japan, this socket will make your routine differential and transmission fluid changes a breeze; especially if those drain and fill plugs have not yet been removed and still have the original torque settings from the factory along with thread lock on there.  Up until our introduction of these sockets, the only tool people thought to use was a bare 1/2" drive ratchet or 1/2" drive breaker bar.  Those who have performed this task before, know that those options do NOT fit the plug properly!  The 1/2" drive square is a few millimeters too narrow and is also too long to fit in the plug.  Unnecessary effort is wasted holding the wobbly ratchet up to the plug, holding it steady and centered while still managing to turn it.  You are also rounding off that plug.  Wondering if there is a real tool for this job?  This is it.  This special socket fills the square plug perfectly.  Use this socket with any standard 1/2" drive ratchet or 1/2" drive breaker bar, but not for use with impact equipment.  Due to its hexagonal shape, this socket can also be used with a 24mm offset wrench.  This socket is especially helpful to those who regularly participate in track events and a huge blessing to those who have upgraded differentials and transmissions whos fluid change intervals are more frequent.***Not for use with impact equipment.
