GMC P25 Main Bearing Set

Your P25 is a prized possession.

Select Your VehicleGMC automobile enthusiasts have become used to a certain level of reliability when driving their P25 around town. When your GMC P25 left the factory, it was destined for a person with discerning taste who prioritizes trusted quality in their automobile. Anyone who owns a GMC knows that when it comes to repairing their automobile only the most superior replacement parts will do. The vehicle in your driveway symbolizes the best in class when it comes to all the vehicles on the road today.

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

A lack of proper lubrication for your internal engine components can result in intense friction and heat and lead to total engine failure. 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 P25 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 P25. 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.
