Although zillions of Mud guys are using the Centerforce clutches with apparently good results, I sure wished I had more respect for those clutches. The weights on the pressure plate fingers are a bit of a sales gimmick, would be better if they worked in the opposite direction. What they do is increase holding/gripping/locking pressure as your RPM/speed increases, would be better if they created instantaneous locking pressure (off the line), then backed off as the RPM/speed increased. You need instant locking pressure to get your big tires rolling, then less pressure to keep them rolling at highway speeds. I'm thinking heavier duty/higher pressure clutches without the weights would be the better deal ???
