A crawler track guide rail having an upper elongated surface engagable with the shoes of a crawler track, a lower surface engagable with a crawler track support frame, and a foot which extends downward into the frame to transfer load resulting from the engagement of the shoes with the guide rail to the frame. The guide rail has at least one elongated lower surface and may have two elongated lower surfaces which are engageable with the frame. Where there are two elongated surfaces of the guide rail in engagement with the frame, the foot of the guide rail is positioned between the two elongated surfaces. The guide rail has a plurality of fasteners for retaining it on the crawler frame extending through the guide rail and the frame The fasteners have a selected tolerance fit with the frame and the foot of the guide rail has a smaller tolerance fit with the frame than that of the fasteners. Thus, the foot fits relatively snugly with the frame to thereby assist with transfer of the load on the guide rail to the frame through the foot rather than through the fastener members.
