The stage 1X upgrade from Xtreme Outback is designed to provide the ultimate solution for highly tuned vehicles necessitating a significant increase in torque capacity but still requiring driveability for street applications. 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 500 series kit includes heavy duty pressure plate with increased clamping force, sprung or rigid organic friction disc (depending on the application) and a flywheel. The kit also includes alignment tool, release bearing & spigot bearing/bush where required. Xtreme Outback also offer a range of different kit options for those looking for replacement hydraulics or accessories.
