Chevrolet R20 Main Bearing Set

Your R20 is a prized possession.

You purchased your R20 because its reliability and value agreed with your nature; so why would you settle for second rate when it comes to the highest quality auto parts? Chevrolet vehicle owners have become used to a certain level of reliability when driving their R20 around town. Your Chevrolet dealership isn't the only place to buy the best repair parts to fix your R20. When your Chevrolet R20 left the factory, it was destined for a person with discerning taste who prioritizes long-lasting quality in their automobile.

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 Chevrolet R20 main bearings are installed there. For decades, a metal alloy material called Babbitt has been used to make engine main bearings, because its gall-resistant surface makes it ideal to act as a buffer in the space between the crankshaft and main bore in your Chevrolet R20. 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.
