Chevrolet R20 Main Bearing Set

Keeping your R20 in top shape is your top priority.

Select Your VehicleIt's not all the time that you realize that you have to buy a replacement Main Bearing Set to fix your vehicle. You bought your R20 because its reliability and value appealed to your senses; so why would you be okay with anything but the best when it comes to the highest quality auto parts? Anyone who drives a Chevrolet knows that when it comes to maintaining their car, truck, or SUV only the highest quality replacement parts will do. The vehicle in your driveway symbolizes the best in class when it comes to all the vehicles in today's marketplace.

What Main Bearing Set does for your vehicle.

A lack of proper lubrication for your internal engine components can result in intense friction and heat and lead to total engine failure. The places where the most rotary movement occurs in your engine are where the crankshaft spins through the main bore, and that is why your Chevrolet R20 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 Chevrolet R20. 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.

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

Bring your R20 back to life with the highest quality new or rebuilt parts from the experts at Car Parts Discount.
