These shells sit at the big end of the connecting rods, where the rod meets the crankshaft journal. They're a wear item that gets replaced as a set when a triple's crank is reground or when the rod bearings are being renewed during a rebuild.
This is the standard undersize in the shell lineup. If your crank has been reground, you'll want to check journal size against the undersize options rather than defaulting to standard.
