A tensioner for an endless drive member is provided, comprising: a base having a proximal end and a distal end and is mountable at the proximal end to a stationary structure; a first tensioner arm that is pivotable relative to the base about a common axis; a first tensioner pulley that is mounted for rotation on the first tensioner arm about a first pulley axis that is spaced from the common axis; a second tensioner arm that is pivotable relative to the base about the common axis; a second tensioner pulley that is mounted for rotation on the second tensioner arm about a second pulley axis that is spaced from the common axis and spaced from the first pulley axis; a tensioner biasing member that is engaged between the first and second tensioner arms to urge the first and second tensioner pulleys towards each other; a first tensioner arm damping arrangement including a first radial damping portion positioned radially between the first tensioner arm and the base, and a first axial damping portion, wherein the first radial damping portion and the first axial damping portion cooperate to provide damping to movement of the first tensioner arm; a second tensioner arm damping arrangement including a second radial damping portion positioned radially between the second tensioner arm and the base and a second axial damping portion, wherein the second radial damping portion and the second axial damping portion cooperate to provide damping to movement of the second tensioner arm; and a damping system biasing member that is positioned to apply an axial biasing force to the first and second axial damping portions to generate friction thereat.
