All clutch plates are made of either 6061 T6 or hightempered steel with our own-race proven Kevlar material.
Each plate design was tested so that maximum performance is achieved. Different groove patterns were designed for maximum oil circulation and heat dissipation. The steady flow of lubricant will cool and determine the longevity of
your clutch.

All Big Twin kits are packaged with frictions and steels and a pre-measured stack height for easy installation.
