Heavy Duty Friction Disc

The heavy duty friction disc (MPN 71018) is a critical clutch component engineered for high-performance manual transmissions, specifically designed for Brinn transmission systems. This friction disc serves as the primary engagement surface between the engine's flywheel and the transmission input shaft, translating engine power into rotational force while accommodating the mechanical shock of gear engagement. Whether you're building a street machine, drag vehicle, or high-horsepower custom setup, a quality friction disc is non-negotiable for reliable power delivery and consistent clutch modulation.

Heavy duty friction discs like this model feature a specially formulated friction material bonded to a steel backing plate, engineered to withstand elevated temperatures and repeated engagement cycles without glazing or material degradation. The friction material's coefficient is calibrated to provide positive bite without excessive drag, enabling smooth launches under boost or nitrous while resisting chatter during partial-throttle transitions. The compact 3.85 x 4.35 inch footprint with minimal thickness ensures precise fitment within Brinn transmission internals, where dimensional accuracy directly impacts clutch modulation and longevity.

Mechanics and performance builders select this friction disc when replacing worn Brinn transmission clutch assemblies or upgrading to stronger engagement characteristics on modified engines. Installation requires proper transmission access and knowledge of clutch pack clearances; this disc must be paired with a compatible pressure plate and flywheel for optimal results. If you're experiencing slip under acceleration, inconsistent engagement feel, or are upgrading to higher boost levels, this heavy duty friction disc delivers the durability and performance characteristics needed for demanding applications.
