With higher and higher horsepower, stronger clutches are needed. However, it can be tough to find something that will handle the amount of power while still being reasonable on your left leg. Clutch Masters' multi-plate clutches are designed to address this and more. The cover plate is made out of machined aluminum, which reduces deflection and strengthens the clutch to handle more power. Even with a tough plate, this multi-plate clutch kit still engages and disengages quickly and smoothly using Clutch Masters' unique QR System. This system incorporates 3 spring bolts that will reduce the pressure needed to operate the clutch while also reducing clutch noise and chatter by up to 50%!
The two discs in each of these multi-plate clutch kits are made of ceramic or fiber tuff, or a combination of both depending on the application (please see application notes for your Scion xB). Most kits also includes a steel or aluminum flywheel as well (please see application notes for your Scion xB). Most applications are available in a smaller and more aggressive 725 series or a larger and easier 850 series. Both options are on average 50% lighter than stock assemblies.
