A friction casting for use in a railroad car truck between a side frame column and a bolster pocket slanted wall has a slanted wall to face and be in contact with the bolster pocket slanted wall and a vertical face in contact with the side frame column. The friction casting has a hollow interior, except for a support rib which is perpendicular to the slanted wall of the casting and supports the slanted wall of the casting generally at the zone of contact with the bolster pocket slanted wall. The support rib transfers the load from the slanted face of the friction casting to the vertical face of the friction casting generally at the center of pressure thereof.
