These Cerametallic 6 Paddle Drive Plates from Helix have a rigid hub design which has no form of damper or segment cushioning. A rigid hub is designed for more demanding working conditions which require high strength and durability. The cerametallic friction material is split into sections which are riveted on to the drive plate and are thicker than sintered drive plates. This provides a higher heat soak capacity and better heat dissipation. This type of material is mainly used in rally applications. There is a wide range of spline sizes available to suit most applications.
