Car aficionados know that a brand you can trust is built into each GMC, and know that only the best repair R3500 parts will suffice when repairs are needed. When your GMC R3500 was born, it was destined for a driver who wants longevity in their automobile. Your GMC dealership isn't the only place to locate genuine or original equipment quality parts to repair your R3500. Obviously, you bought your R3500 because you knew that you wanted horsepower and rugged design both rolled up into one car, truck, or SUV.
Your engine can totally break down from lack of lubrication; resulting in intense friction and heat. 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 R3500 main bearings are installed 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 R3500. When properly lubricated, friction and heat are minimized as the main bearings protect your internals for, hopefully, the life of your car or truck.
