Its design accounts for a larger stud spacing, measuring 79mm diagonally. The cylinder sleeve has an outer diameter of 62.5mm, sized for particular engine layouts so it seats properly and works as intended inside the engine.\u003c\/p\u003e\u003ch3\u003ePiston Details\u003c\/h3\u003e\u003cp\u003eThe included piston uses a 15mm pin diameter and a 42mm pin length.
