GMC R2500 Main Bearing Set

Great cars and trucks like your R2500 need great parts.

It's not all the time that you realize that you have to buy a replacement Main Bearing Set to fix your car or truck. You purchased your R2500 because its dependability and trusted quality agreed with your nature; so why would you settle for second rate when it comes to superior quality auto parts? Anyone who owns a GMC knows that when it comes to repairing their vehicle only the absolute best replacement parts will do. GMC vehicle enthusiasts have come to expect a certain level of reliability when driving their R2500 around town.

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 R2500 main bearings 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 R2500. When properly lubricated, friction and heat are minimized as the main bearings protect your internals for, hopefully, the life of your car or truck.
