Since they are TORQUE TO YIELD stretch bolts, you need to replace these when you replace your rod bearings or get your rods rebuilt. Anytime a TTY bolt is loosened, it needs to be replaced so that it can be torqued properly. Don't skip this step during your rebuild or you'll regret it later. 

Kit includes 8 rod bolts and 8 rod nuts for 1995-2004 2.4L & 2.7L, 12 rod bolts and nuts for 1996-2004 3.4L V6 OE parts.
