This kit utilises a concentric heavy duty release bearing and aluminium boss, with modification to the standard gearbox nose.

Utilises a high quality cast aluminium slave cylinder and heavy duty all steel sealed ball bearing. Comes complete with a circlip for better attachment to the slave cylinder. For use in competition or in applications where a heavier duty component is required.

Before use please carry out a “dry run” checking the actuation of the slave cylinder over the entire clutch pedal stroke. Over extension will result in the bearing being forced off the end of the inner shaft when the clutch is depressed.

Mounting plate height 40mm
Slave cylinder height 60mm open, and 40mm fully closed
Assembled heights 100mm open and 80 mm fully closed
***Shims can be provided on request

Note:It is necessary to shorten the original thrust bearing tube and substitute the original bolts for the longer ones supplied. See the second picture for an illustration of how to achieve this. There is no need to disturb the front gearbox bearing.

Please specify a flat release bearing for curly finger diaphragm springs and a radiused bearing for flat diaphragm springs.

A mechanical clutch pedal stop must be fitted to prevent the slave cylinder over throwing, which will lead to fluid leaks and seal damage.

Please see the Fitting Instructions for more information.
