A railcar coupler having a head portion extending from a shank portion, the coupler head portion is configured to couple to a first coupler knuckle for coupling the railcar coupler to a second railcar coupler of an adjacent railcar. The coupler has weight reduction features that also are configured to provide strength to the coupler when handling forceloads. The coupler may have a head with a front face with bores provided in the front face a cavity extending through the coupler, a guard arm with cavities formed therein, and a shank having a plurality of longitudinal cavities and adjacent ribs separating the cavities.
