5.5 Optimum Clutch 2 Disc 26sp

The 5.5 Optimum Clutch 2 Disc 26sp is a precision-engineered racing component designed for high-performance applications where rapid gear changes and reduced rotational mass are critical for victory. This Quarter Master Optimum-V kit serves professional racers and dedicated track enthusiasts who need a clutch capable of handling extreme heat and torque without the bulk of a traditional street unit. By utilizing a compact 5.5-inch diameter, this assembly significantly lowers the moment of inertia, allowing the engine to rev more freely and shortening shift times during competitive events.

Engineered with a dual-disc configuration, this clutch kit utilizes ceramic friction materials to provide aggressive engagement and superior thermal stability under racing conditions. The 5.5 Optimum Clutch 2 Disc 26sp features a 1-5/32 inch by 26-spline interface and a rigid hub design, ensuring a direct and positive connection between the crankshaft and the input shaft. Its lightweight construction minimizes parasitic power loss while maintaining the structural integrity required for high-RPM operation across various motorsport disciplines.

This specialized racing clutch is ideal for road racing, circle track, and other closed-course environments where every millisecond on the stopwatch counts. Because the 5.5 Optimum Clutch 2 Disc 26sp is a race-specific part, it requires a compatible flywheel and release bearing setup to function correctly within a performance drivetrain. Drivers seeking to buy a reliable, high-specification clutch will find this Quarter Master unit offers the durability and consistent pedal feel necessary for the most demanding racing specifications.
