A knuckle for a rail car coupler that reduces bending of an intermediate portion of the pivot pin that coupled the knuckle to a rail car coupler. The knuckle has a body with a throughbore defining a first bearing surface at a first end of the throughbore and a second bearing surface and a second end of the throughbore. A support extends from the body into the throughbore and includes a third bearing surface positioned between the first bearing surface and the second bearing surface. When a pivot pin is positioned in the throughbore, it will contact the first bearing surface, the second bearing surface, and the third bearing surface, with the third bearing support protecting against bending of the pivot between the first and second bearing surfaces.
