GMC C15 Main Bearing Set

Keeping your C15 in top shape is your top priority.

The vehicle in your driveway is head and shoulders above the rest compared to all the other cars, trucks, and SUVs in today's marketplace. GMC vehicle enthusiasts have become used to a certain level of reliability when driving their C15 around town. Obviously, you bought your C15 because you wanted to buy performance and great value both impeccably combined into one car, truck, or SUV. Auto enthusiasts appreciate the strong looks built into each GMC, and understand that only the best repair C15 parts will suffice when your car or truck needs fixing.

Don't go too long without fixing your Main Bearing Set... here's why.

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 C15 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 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.

Good products, great prices, the best people.
