GMC C15 Main Bearing Set

Your C15 is a prized possession.

Make no mistake, you didn't buy your C15 unless you wanted to buy horsepower and great value both rolled up into one automobile. While it may not be difficult to buy replacement parts for GMC vehicles, these days the necessity for nothing but the highest quality are required to maintain your car or truck. When your GMC C15 left the factory, it was destined for a driver who prioritizes trusted quality in their automobile. Anyone who operates a GMC knows that when it comes to fixing their vehicle only the most superior replacement parts will do.

The function and purpose of Main Bearing Set.

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 C15 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. 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.

We've got all the top brands.
