Stage 2 Cerametallic clutches are designed to handle the abuse of high power modified engines. Our Cerametallic friction material can handle much more abuse than stock type disc assemblies without slipping and fading. The THICK discs have better heat capacity and therefore better durability in demanding applications. Even with the THICK disc, our three and four puck designs typically have less inertia than a stock disc and work well for street, rally and track use.
