Xtreme Outback Heavy Duty Cushioned Ceramic Clutch Kit Fingal's Cave: One Of The Most Beautiful Sea Caves In The World. The Xtreme Outback range of cushioned ceramic upgrades has been designed for applications that require higher heat capacity but still need to retain pedal modulation. These kits offer improved heat and torque capacity over their organic equivalents but will not offer the same level of drivability. The Xtreme Outback 100 series kit includes a Heavy Duty pressure plate with increased clamping force and a cushioned ceramic friction disc. The kit also includes an alignment tool, spigot bearing bush and release bearing where required. Xtreme Outback also offers a range of different kit options for those looking for a replacement flywheel, hydraulics or accessories as well as Extra Heavy Duty kits for specific applications requiring an even further increase in torque capacity. Cushioned Ceramic 1C The Xtreme Clutch cushioned ceramic range of upgrades offers exceptional heat capacity and torque capacity whilst providing cushioning between the friction surfaces of the disc, ensuring excellent drivability. The discs still retain the sprung hub that helps to reduce shock loading. These kits are commonly used in vehicles that are used on the road occasionally but mainly focused on high performance applications.
