SCREAMIN' EAGLE VARIABLE PRESSURE CLUTCH

Get more performance from the original equipment clutch. The Screamin' Eagle variable pressure clutch is designed to help put the added power from a Screamin' Eagle Stage kit to the pavement. This bolt-on kit harnesses the centrifugal force of spinning weights to increase the clutch capacity as the engine speed increases. The mechanism applies increasing pressure to the stock clutch pressure plate as RPM rises. The result : High torque-handling capacity without increasing clutch lever effort at idle. Kit fits behind most stock derby covers with no modifacations.
