Barnett Scorpion Clutch Kit features over twice as much fric-
tion surface area compared to stock clutch. Scorpion Clutches
provide a positive engagement and release. The kit incorpo-
rates six heavy duty coil springs. In addition, an extra spring set
with a different spring rate is included which allows the clutch to
be tuned for street or race application depending on usage.
Tunability is easy without removal of the primary cover. Barnett
friction plates are compatible with any primary oil. Each kit is
designed to be used with stock type clutch basket.
