A lack of proper lubrication for your internal engine components can result in intense friction and heat and lead to total engine failure. The places where the most rotary movement occurs in your engine are where the crankshaft spins through the main bore, which is why you will find your GMC Sierra 1500 main bearings there. These main bearings are made from a composite metal called Babbitt (iron, zinc, copper, aluminum, and more), because its gall-resistant surface makes it ideal to act as a buffer in the space between the crankshaft and main bore in your GMC Sierra 1500. When properly lubricated, friction and heat are minimized as the main bearings protect your internals for, hopefully, the life of your car or truck.
