GMC G25 Main Bearing Set

You enjoy taking care of your G25.

Select Your VehicleWhen your GMC G25 was born, it was destined for a person with discerning taste who prioritizes longevity in their automobile. Obviously, you didn't buy your G25 unless you understood you would be getting performance and great value both impeccably combined into one car, truck, or SUV. It's not every day that you discover you need a replacement Main Bearing Set to repair your car or truck. GMC automobile enthusiasts have come to expect a certain level of reliability when driving their G25 around town.

Why Main Bearing Set replacement is so important.

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 G25 main bearings are installed 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 G25. When properly lubricated, very little friction is created around the engine main bearings and they will last the life of the vehicle.

High quality parts, great prices, knowledgeable professionals.
