New Comet 218875A, 103HPQ Drive Clutch for
Polaris Xpress 400
Fits 1996 and 1997 models
The 103 HPQ allows for a quicker shift out and a greater top end speed. Reported performance enhancements of 25% over the OEM clutch with performance kits is typical.
The gains in the 103HPQ ATV clutch is in the larger diameter pulley and the greater sheave angles, giving more ratio and less wear on the belt and sheave faces. Greater degree angle of sheaves allows less resistance of movable sheave allowing smoother up shift because the movable face is pushing the belt instead of pinching the belt to the outer diameter of the clutch. With greater degree of angle less cam arm weight is required, causing less wear on belt, pulley faces and cam arm bearings. Also faster back shifting which reduces sheave wear on the driven unit because you do not have as much torsional tension to over come the weights in the drive system. This results in a reported performance enhancement of up to 25%.
