ACT Clutch Kits, Mod-Twin Clutches & XACT Flywheels Build a matched manual-transmission drivetrain with ACT performance clutch kits, replacement clutch discs, pressure plates, XACT flywheels and installation components. Black Ops Auto Works carries Advanced Clutch Technology parts for street cars, track builds and competition applications, including vehicle-specific single-disc kits and Mod-Twin multi-disc systems. Shop by exact ACT part number and your complete engine and transmission combination to find the right configuration for your build. Choose Your Part Start with the engine’s expected torque output and how the car will be driven. A daily driver needs predictable engagement, while a dedicated race car may prioritize fast shifts and repeated high-load operation. Compare the exact kit’s published torque capacity, pressure plate, friction material and hub design. ACT engine-torque ratings are measured at the engine; they should not be treated as interchangeable with wheel-t...

Twin-Disc and Triple-Disc Clutch Systems Multi-disc clutches use multiple friction discs within a matched assembly to provide additional working friction surfaces. This gives manufacturers another way to achieve torque capacity without relying solely on a larger single disc or increased clamping force. Disc count alone does not determine capacity, pedal effort, or street manners. Compare friction material, disc diameter, pressure-plate design, and the manufacturer’s intended use. A triple-disc system is not automatically the best choice for every high-o...
