Replacement 5-80 Series Constant Velocity "H" yoke. Weasler CV Wide Angle yokes are made from steel to withstand robust conditions, and engineered for a precise fit. CV wide angle yokes allow a rotating shaft to transmit power through a variable angle, at constant rotational velocity, without an appreciable increase in vibration or friction. The center yoke connects the two outboard yokes to transmit power while maintaining constant angle to minimize vibration.
