Racing Release Bearings

Mechanical Bearings

When fitting a new racing clutch, a new release bearing maybe needed, depending on the diameter and shape of the face.
Helix Autosport design and manufacture a range of custom bearings to be used with our race clutches. 
More information can be found on our 'Bespoke Bearings Page.' 

Concentric Slave Cylinders

If a flat faced Concentric slave cylinder or flat faced release bearing is to be used, then a Top-Plate (TP) must be added to the top of your cover assembly.
This sits on top of the fingers for the release bearing to actuate against. 

Adding a top pad will increase the setup height of the cover by 6mm.


Gearbox Splines

Helix Autosport manufacture our driven plates with the choice of 45 different gearbox splines.
Click on the racing clutch pages to view our list of splines.
The spline information is given as: the diameter of the spline and the number of teeth. For example 1" x 23Teeth.
If your spline is not listed, please supply us with the dimensions and we can manufacture it for you, however please allow up to 4 weeks for this service and prices are on application.



Racing Clutch Mounting Bolts

 Helix Autosport supply two types of bolts to secure our racing covers to the flywheel:

  • 5/16 UNF NAS bolts, these pass through from the rear of the flywheel and need to be a close tolerance fit through the flywheel. The heads of the bolts are located against a lip machined on the rear of the flywheel to prevent rotation, and are used in conjunction with K-lock nuts.
  • High quality socket head cap screws (min. tensile 10.9) diameter 8mm or 5/16” UNF located through the cover assembly and screwed directly into the flywheel.

More information on: torque figures, dimensions and fitting procedure for our racing clutches can be downloaded in our PDF catalogue.
