Explore application-specific packages from McLeod Racing, ACT, Clutch Masters, OS Giken, XClutch, and other brands represented in this collection. Compare street-oriented and competition configurations for compatible domestic and import manual-transmission builds, including modified engines that require additional clutch capacity. 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.
