COMET INDUSTRIES 103 HPQ (High Performance Quad) Clutch The 103 HPQ ATV clutch has a larger diameter pulley and greater sheave angles than OEM to provide more ratio and less wear on the drive belt and sheave faces The increased angle of the sheaves means smoother up shift because the moveable face pushes (not pinches) the belt to the outer diameter of the clutch Less cam arm weight is required which results in less wear on the belt, pulley faces and cam arm bearings Faster back shifting reduces sheave wear on the driven unit since there is less torsional tension to overcome the weights in the drive system Claims of as much as 25% enhanced performance have been reported in testing
