In addition, ARP Main Studs can safeguard the threads of your engine block, providing an extra layer of protection against potential damage. \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eWhen opting for main studs instead of factory bolts,\u003cspan style=\"color: #ff0b0b;\"\u003e it's important to note that the engine builder should mic the bores. \u003cspan style=\"color: #000000;\"\u003eU\u003c\/span\u003e\u003c\/span\u003e\u003cspan style=\"color: #000000;\"\u003esi\u003c\/span\u003eng studs may require a line hone to ensure proper fitment and alignment. A line hone is a machining process that can be used to resize and reshape the main bearing bores, ensuring that they are perfectly round and concentric. This is crucial for ensuring proper oil clearance and preventing premature bearing wear. By mic'ing the bores and performing a line hone if necessary, engine builders can ensure that the main studs are installed correctly and that the engine will perform reliably and at its best.\u003c\/span\u003e\u003c\/p\u003e\n\u003cdiv dir=\"ltr\" role=\"presentation\"\u003e\n\u003ch3\u003e\u003cspan\u003eInstallation Instructions\u003c\/span\u003e\u003c\/h3\u003e\n\u003col start=\"1\"\u003e\n\u003cli\u003eThoroughly clean all threaded holes in the engine block.
