The stage 1 upgrade from Xtreme Outback is designed to provide a significant increase in torque capacity whilst retaining driveability for daily driven vehicles. These kits are ideal for vehicles that have been tuned, tow heavy loads regularly, are fitted with larger tyres or heavy accessories and that are used in extreme conditions. The 400 series kit includes heavy duty pressure plate with increased clamping force, sprung or rigid organic friction disc (depending on the application) and a concentric slave cylinder. The kit also includes an alignment tool & spigot bearing/bush 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.
