The vehicle in your driveway is head and shoulders above the rest when it comes to all the vehicles in today's marketplace. You purchased your K25 because its reliability and longevity agreed with your nature; so why would you be okay with second best when it comes to superior quality auto parts? Make no mistake, you didn't buy your K25 unless you understood you would be getting horsepower and rugged design both rolled up into one vehicle. Auto enthusiasts know that a brand you can trust is built into each GMC, and know that only top quality repair K25 parts will suffice when repairs are needed.
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, and that is why your GMC K25 main bearings are installed there. These main bearings are made from a composite metal called Babbitt (iron, zinc, copper, aluminum, and more), 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 K25. 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.
