108 4PRO Series

We call the 108 4-Pro the Super Clutch as it utilizes four clutch weights rather than three, greatly enhancing tuneability. Arms can be used in sets of two, allowing you to zero in on the amount of weight desired, and a captivated tower allows the shouldered cover bolts to virtually eliminate tower spreading. A fourth load bearing member increases the roller and button life. Moveable sheave bushing, higher heat and wear resistance also extends the clutch performance.
