This is a gearbox stud, part number 21-1813, used to hold gearbox castings or components together on Triumph applications. Our records on this one are thin - it shows up plainly as a stud for the gearbox, but we don't have detail on exactly which gearbox casting or year range it's tied to.

Studs like this one thread into a casting on one end and take a nut on the other, letting you draw two gearbox parts together with even clamping pressure. Beyond that basic job, we don't want to guess at specifics we can't confirm.
If you've got the part number off your own gearbox or parts book, give us a call and we'll confirm fitment before you order.
