An endless track assembly comprises a pair of laterally spaced link assemblies each having a plurality of articulated links. Each pair of interconnected links is mounted on the end of a pin having a torsional track bushing mounted thereon. The torsional track bushing includes a metallic sleeve spaced longitudinally from one of the links and an elastomeric-based bushing secured between the metallic sleeve and such link for permitting relative torsional movements therebetween. The elastomeric-based bushing may constitute an annular member entirely composed of an elastomer, an elastomeric member secured on a metallic ring, or a plurality of elastomeric discs interleaved between a plurality of metallic discs.
