Stage 1AX Sprung Organic Extra Heavy Duty Clutch Kits are recommended for Street use and light track use in vehicles with minor engine modifications.

An increased clamp load over stage 1 kits, recommended for street and light track use in higher powered vehicles.

Note: for vehicles using a conventional external slave cylinder, a release or throw-out bearing is included in kits. For cars using a concentric slave cylinder (CSC), the release bearing is part of the CSC. Changing CSC is recommended when replacing the clutch as it involves removing the gearbox to install.

Where a replacement flywheel or CSC is required, consider an alternate kit listed with our Parts Finder that includes these options.
