The "Scorpion" clutch features over twice as much friction area compared to the stock clutch, and provides a smooth, linear, positive engagement and release for ease in finding neutral as well as smooth, positive shifting. Steel spacers on the clutch pack ends ensure no wear on the aluminum surfaces. The "Scorpion" clutch incorporates 6 Heavy-Duty coil springs instead of the stock diaphragm spring. In addition, Barnett includes extra spring sets to tune the clutch from Mild Street to wild race. Tune-ability is easy without the removal of the primary cover. The Barnett Scorpion clutch is designed for wet or semi-wet applications and is compatible with any primary oil. Can be fitted with standard tools, a special Scorpion clutch hub tool to ease removal is separately available, as well as clutch lock plates to lock the outer clutch basket to the inner hub. 2836 BARNETT "SCORPION" CLUTCH For Pro-Clutch on 1990-1997 Evo Big Twins.
