You bought your K15/K1500 Pickup because its reliability and trusted quality agreed with your nature; so why would you settle for anything but the best when it comes to superior quality auto parts? GMC automobile enthusiasts have become used to a certain level of dependability when driving their K15/K1500 Pickup around town. While it's not hard to find replacement parts for GMC vehicles, these days the necessity for nothing but the absolute best are required to repair your car or truck.

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 K15/K1500 Pickup main bearings are installed there. For decades, a metal alloy material called Babbitt has been used to make engine main bearings, which is just slightly softer than the forged or cast crankshaft and the main caps in your GMC K15/K1500 Pickup. When properly lubricated, very little friction is created around the engine main bearings and they will last the life of the vehicle.

We've got what you are looking for.
