Clutch Assembly 5.5in

The Clutch Assembly 5.5in Pro-Series Triple Disc from Quarter Master is purpose-built for serious performance drivers and drag racers who demand consistent, repeatable engagement under extreme loads. This multi-disc unit replaces stock single-disc assemblies, delivering the clamping force and durability required for high-horsepower builds, forced induction applications, and sustained competition use. Whether you're running a turbocharged street car, a dedicated bracket racer, or a high-output engine swap, this clutch assembly provides the reliability needed when stock components fall short.

Quarter Master's triple-disc design increases friction surface area compared to conventional dual-disc units, allowing the clutch to handle elevated torque while maintaining a manageable pedal effort. The 5.5-inch diameter provides an optimal balance between engagement speed and thermal capacity, preventing the chatter and slippage common in underdated assemblies. The Pro-Series construction incorporates precision-machined components and heat-treated materials engineered to withstand repeated full-throttle launches and sustained power delivery without degradation. This assembly's compact footprint—measuring 7.3 x 4.1 x 7.4 inches and weighing just 10.61 lbs—makes it a direct replacement option for many modern performance platforms without requiring extensive frame or transmission modifications.

This clutch assembly is ideal for engine builders, tuners, and racers stepping beyond factory torque ratings or transitioning to independent racing sanctioning bodies with stricter clutch specifications. Installation requires proper flywheel preparation, pressure plate evaluation, and pilot bearing alignment—tasks best handled by experienced transmission specialists familiar with performance clutch systems. Quarter Master components are commonly specified in NHRA-legal builds, road-course competition cars, and street applications where thermal stability and engagement consistency are non-negotiable. Verify compatibility with your specific transmission, engine combination, and intended use case before purchase.
