Suitable for the following gearboxes:

We recommend carefully disassembling and identifying the synchros (9° or 6°40' angle, friction sector, etc.) in each gearbox, as we have observed some mixtures.

The gearbox numbers on the identification plate are not the most reliable way to identify the correct part.

• The fork is suitable for "original ball thrust bearing" type mounting or for conversion with a guided thrust bearing.
• Mounting instructions provided.

It may be necessary to modify the fork by adding a diameter tube to the fork boss to move the fork/stop assembly forward.
