What Makes Innovators West Different?
Inside the light weight billet aluminum cover is a free floating wet friction clutch pack assembly that utilizes spring loaded inertia
rings to dampen crankshaft harmonics over a wide RPM range. The rings work in conjunction with clutches to provide outstanding
dampening action. That action does generate some heat, and we use a small amount of fluid inside that acts as a lubricant as well
as dissipates heat to the outer body.
