GMC K25 Main Bearing Set

You enjoy taking care of your K25.

Select Your VehicleThe vehicle in your driveway is head and shoulders above the rest compared to all the other vehicles on the road today. When your GMC K25 left the factory, it was destined for a driver who prioritizes longevity in their automobile. Obviously, you bought your K25 because you understood you would be getting performance and rugged design both impeccably combined into one automobile. You picked your K25 because its dependability and longevity struck a chord inside you; so why would you settle for second rate when it comes to great quality auto parts?

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, which is why you will find your GMC K25 main bearings there. For decades, a metal alloy material called Babbitt has been used to make engine main bearings, 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 K25. Most bearings are cast with lubrication channels, so very little friction is created around the engine main bearings and they will last the life of the vehicle.

There's no reason to delay... checkout is simple and easy.
