GMC C25 Main Bearing Set

You enjoy taking care of your C25.

Select Your VehicleYour GMC dealership isn't the only place to locate trusted parts to repair your C25. Obviously, you didn't buy your C25 unless you knew that you wanted performance and rugged design both impeccably combined into one automobile. When your GMC C25 was born, it was destined for a person with discerning taste who values trusted quality in their automobile. It's not every day that you find yourself in need of a replacement Main Bearing Set to repair your vehicle.

Why Main Bearing Set replacement is so important.

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 C25 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 C25. When properly lubricated, very little friction is created around the engine main bearings and they will last the life of the vehicle.

You've tried the rest, now try the best.
