These bearings are basically the support system for your engine’s crankshaft. The crankshaft is what turns and ultimately powers the wheels, and it doesn't just spin freely in the engine block. These bearings sit between the crankshaft and the block, providing a smooth, low – friction surface for it to rotate on. They handle a lot of stress and load from the pistons firing. The set includes several bearings – upper and lower halves that go around each of the crankshaft’s main journals. Think of them as vital to the entire bottom end of your engine. Without properly functioning main bearings, the crankshaft can't spin smoothly. That smooth spinning is what transfers power efficiently. They are directly responsible for keeping everything aligned and stable down there, preventing a lot of internal vibration. They’re important because wear happens over time. Oil helps, of course, but constant stress and tiny metal – on – metal contact eventually cause these bearings to wear down. When they get worn, you’ll start to lose oil pressure, hear a knocking sound coming from the engine – it's a pretty distinctive sound, almost like a heavy tap, and you’ll notice if it starts happening, especially under load. If you ignore it, things can go downhill quickly. Worn bearings can cause serious engine damage, even catastrophic failure. Replacing them proactively, during an engine rebuild or when you start hearing signs of trouble, is a lot cheaper than replacing an entire engine. We carry a good selection of these, and you can often find a set online at places like Fixparts Online – they usually have pretty competitive pricing.
