GMC C15 Suburban Main Bearing Set

You enjoy taking care of your C15 Suburban.

When your GMC C15 Suburban was born, it was destined for a driver who values trusted quality in their automobile. Anyone who operates a GMC knows that when it comes to maintaining their car, truck, or SUV only the most superior replacement parts will do. GMC vehicle owners have grown accustomed to a certain level of reliability when driving their C15 Suburban around town. The vehicle in your driveway is head and shoulders above the rest compared to all the other cars, trucks, and SUVs on the road today.

The function and purpose of Main Bearing Set.

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 C15 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 C15 Suburban. When properly lubricated, very little friction is created around the engine main bearings and they will last the life of the vehicle.
