It's not a regular occurrence that you discover you need a replacement Main Bearing Set to repair your car or truck. Make no mistake, you didn't buy your G15 unless you knew that you wanted horsepower and rugged design both impeccably combined into one car, truck, or SUV. Your GMC dealership isn't the only place to buy trusted parts to repair your G15. You purchased your G15 because its dependability and trusted quality appealed to your senses; so why would you settle for second best when it comes to superior quality auto parts?
A lack of proper lubrication for your internal engine components can result in intense friction and heat and lead to total engine failure. The moments where your engine's main caps meet the crankshaft are where all the friction and heat come from, and that is why your GMC G15 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 G15. Most bearings are cast with lubrication channels, so very little friction is created around the engine main bearings and they will last the life of the vehicle.
