Helix 5.5” (140mm) Triple Plate Race Clutch Cover Assembly

The Helix 5.5" (140mm) Triple Plate Race Clutch Cover Assembly is designed to transmit very high levels of engine torque in competition vehicles where drivetrain reliability is critical. Its one-piece aluminium construction, lug drive design and compact 140mm diameter work together to provide efficient torque transfer, improved heat management and low rotational inertia for high-performance applications.

The following features explain how this clutch cover assembly achieves its performance characteristics:

• Triple Plate Clutch Configuration: Designed for use with 3 x sintered drive plates, this assembly provides a large friction interface capable of reliably transmitting up to 1450 Nm (1050 lb/ft) of torque, helping you maintain consistent power delivery in demanding motorsport conditions.
• One-Piece Aluminium Cover Construction: The clutch cover is manufactured from a single-piece aluminium body which promotes effective heat dissipation during operation, helping you manage clutch temperatures and maintain consistent performance during prolonged use.
• Lug Drive Design: The integrated lug drive arrangement allows friction material dust to escape more easily from the clutch assembly, helping to reduce contamination within the clutch pack and support reliable engagement characteristics.
• 140mm Compact Diameter: The compact 5.5" (140mm) diameter reduces rotating mass within the driveline, helping you achieve faster engine response and more direct power transfer during acceleration and gear changes.
• Low Moment of Inertia: The lightweight aluminium construction and reduced clutch diameter create a very low moment of inertia, allowing the engine to gain and lose revs more quickly while supporting responsive vehicle control.
• High RPM Capability: Engineered for competition use, the cover assembly is designed to withstand sustained high engine speeds, helping you maintain reliability during prolonged periods of operation at elevated RPM.
• Straight Spring Release System: The clutch cover utilises straight springs specifically designed for use with a curved face release bearing, providing correct release geometry and dependable clutch operation when used with compatible components.
• 48-52mm Fulcrum Point Compatibility: The diaphragn springs are designed around a release bearing fulcrum point range of 48-52mm, ensuring correct clutch actuation characteristics and supporting consistent pedal feel when installed within the specified operating parameters.

This clutch cover assembly helps you manage high torque outputs while maintaining reliable clutch operation during demanding competition use. The combination of lightweight aluminium construction, efficient heat dissipation and low rotational inertia supports responsive engine behaviour and dependable power transmission. For applications where drivetrain components are exposed to sustained high loads and RPM, it is a practical addition to your transmission setup and a smart choice for achieving consistent clutch performance.
