Xtreme Outback twin plate organic kits are designed specifically for high power street applications that require increased torque holding capability as well as driveability for street use. If you have a highly modified 4x4 that has a significant increase in power and torque but still requires driveability for everyday use, these kits are the ideal solution. The Xtreme Outback 500 series kit includes a performance pressure plate with increased clamping force, rigid organic friction discs and flywheel. The kit also includes an alignment tool, spigot bearing/bush and release bearing where required.
