GMC K15 Main Bearing Set

Why you drive your K15.

Select Your VehicleYou bought your K15 because its dependability and longevity appealed to your senses; so why would you be okay with second best when it comes to superior quality auto parts? The vehicle in your driveway is head and shoulders above the rest compared to all the other cars, trucks, and SUVs in today's marketplace. While it's not hard to buy replacement parts for GMC vehicles, these days the necessity for nothing but the highest quality are required to maintain your car or truck. Make no mistake, you didn't buy your K15 unless you wanted to buy performance and rugged design both rolled up into one vehicle.

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. Most bearings are cast with lubrication channels, so friction and heat are minimized as the main bearings protect your internals for, hopefully, the life of your car or truck.

Top-tier components, bargain prices, the best people.
