Abstract: A stack of disk springs are placed between a second piston of a dual hydraulic variable force tensioner system and a hydraulic tensioner arm to allow much higher spring rates if desired. The springs may be stacked in multiple configurations to provide different spring rates. Package space can be reduced depending on the number of springs and orientations of said springs within the tensioner arm.

Abstract: A body of a tensioner arm or guide having a plurality of layers of continuous fiber material. Each layer has fibers oriented in a single direction and extending a majority of a length or width of the material. The fibers of each of the plurality of layers are oriented in a direction other than the orientation of the fibers of adjoining layers of the plurality of layers.
