A frame is disclosed for use with a railway truck. The frame may have a pivot housing, a first arm member extending outward from the pivot housing and having opposing distal ends, and a second arm member substantially identical to the first arm member and extending outward from the pivot housing opposite the first arm member. Each of the first and second arm members may have a generally planar upper plate, a generally planar lower plate, and plurality of webs vertically disposed between the generally planar upper and lower plates. An upper surface of the pivot housing may be generally co-planar with the generally planar upper plates of the first and second arm members.
