Always measure your cylinder bore with a precision bore gauge before purchasing to ensure the correct fit.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Is this ring compatible with standard-bore Raptor engines?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eA:\u003c\/strong\u003e No. This ring is specifically designed for engines that have been machined to a 0.040\" oversize. Installing this on a standard-bore piston will result in improper ring end gap and potential engine failure.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Do I need to gap these rings before installation?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eA:\u003c\/strong\u003e Yes.
