GMC G25 Main Bearing Set

Your G25 is a prized possession.

Your GMC dealership isn't the only place to locate trusted repair parts to fix your G25. When your GMC G25 left the factory, it was destined for a driver who wants trusted quality in their automobile. The vehicle in your driveway symbolizes the best in class when it comes to all the cars, trucks, and SUVs currently being driven today. It's not all the time that you discover you need a replacement Main Bearing Set for your vehicle.

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

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 G25 main bearings are installed there. These main bearings are made from a composite metal called Babbitt (iron, zinc, copper, aluminum, and more), which is just slightly softer than the forged or cast crankshaft and the main caps in your GMC G25. When properly lubricated, friction and heat are minimized as the main bearings protect your internals for, hopefully, the life of your car or truck.

You've tried the rest, now try the best.
