RIGID GBOX ADJUSTER
Right-hand rigid-frame gearbox adjuster, part number 57-0275R.
This is the right-hand gearbox adjuster listed in our records under 57-0275R, used on rigid-frame Triumphs. It's a gearbox mounting/adjuster piece, part of the hardware that lets the gearbox be shifted fore and aft in the frame to set primary chain tension on rigid-frame machines that don't have a swinging-arm or plunger chain adjuster elsewhere in the drivetrain.

Our catalog entry on this one is brief, so beyond the description and the fact that it's the right-hand ('R') side piece of a pair, we don't have more detail on file. If you're sourcing this for a rigid gearbox rebuild, call the shop and we'll confirm fitment against your frame and gearbox casting before you order.
