The vehicle in your driveway is head and shoulders above the rest compared to all the other cars, trucks, and SUVs currently being driven today. Your GMC dealership isn't the only place to locate trusted repair parts to fix your K15. GMC automobile enthusiasts have come to expect a certain level of reliability when driving their K15 around town. It's not all the time that you find yourself in need of a replacement Main Bearing Set to repair your car or truck.

The function and purpose of Main Bearing Set.

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

Good products, great prices, the best people.
