GMC K25 Main Bearing Set

Why you drive your K25.

Your GMC dealership isn't the only place to buy genuine or original equipment quality replacement parts for your K25. Anyone who operates a GMC knows that when it comes to repairing their automobile only the most superior replacement parts will do. While it's not hard to locate replacement parts for GMC vehicles, these days only the absolute best are required to maintain your car or truck. The vehicle in your driveway is head and shoulders above the rest when it comes to all the cars, trucks, and SUVs currently being driven today.

Don't go too long without fixing your Main Bearing Set... here's why.

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, which is why you will find your GMC K25 main bearings 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 K25. When properly lubricated, friction and heat are minimized as the main bearings protect your internals for, hopefully, the life of your car or truck.

The best parts are right around the corner.
