Adjustable Hydraulic Release Bearing
Compatible with 184 mm and 200 mm clutches.
TENACI’s adjustable hydraulic release bearing is designed to fit clutches from Tenaci, Tilton, Ace Racing, Quartermaster, Sachs, AP Racing, and more. This universal bearing features multiple bolt patterns and can be adapted to fit most gearboxes with minor modifications. Adjustable in height/length to suit various clutch setups and gearbox combinations.
Compatible Gearboxes:
Toyota V160 gearbox
BMW ZF gearbox*
*Note: For ZF gearboxes, the sleeve that the original throw-out bearing slides on must be removed.

Master Cylinder Compatibility:
You can use any suitable master cylinder, provided you follow two key guidelines:
The master cylinder must supply enough fluid volume (typically not an issue, as most clutches require low displacement).
You must use a pedal stop to avoid overextending the bearing and pressing against the clutch diaphragm spring.
A larger master cylinder (0.75") results in a firmer pedal with a shorter travel before disengagement.
A smaller master cylinder (0.625") provides a lighter pedal feel but a longer pedal travel.
A medium-sized cylinder (0.7") offers a balance between the two.
General Info:
This is a universal hydraulic release bearing. While it fits many gearboxes with minimal or moderate modifications, it greatly simplifies the installation of custom clutch systems.
Important Note:
Because this bearing fits various gearboxes and aftermarket clutch systems, a pedal stop (or clutch stop) is mandatory. This prevents over-travel and protects both the diaphragm spring and the bearing itself. Proper adjustment is required during installation — this applies to all aftermarket clutch solutions.
