Your engine can totally break down from lack of lubrication; resulting in intense friction and heat. The places where the most rotary movement occurs in your engine are where the crankshaft spins through the main bore, and that is why your GMC R1500 Suburban main bearings are installed there. These main bearings are made from a composite metal called Babbitt (iron, zinc, copper, aluminum, and more), which is just slightly softer than the forged or cast crankshaft and the main caps in your GMC R1500 Suburban. Most bearings are cast with lubrication channels, so friction and heat are minimized as the main bearings protect your internals for, hopefully, the life of your car or truck.
