Jeep J-4500 Main Bearing Set

Your J-4500 is a prized possession.

It's not a regular occurrence that you discover you need a replacement Main Bearing Set for your car or truck. When your Jeep J-4500 was born, it was destined for a driver who values versatility in their automobile. You purchased your J-4500 because its adventure and a fun driving experience struck a chord inside you; so why would you settle for second rate when it comes to superior quality auto parts? Make no mistake, you didn't buy your J-4500 unless you wanted to buy youthfulness and great value both rolled up into one car, truck, or SUV.

The function and purpose of Main Bearing Set.

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 Jeep J-4500 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 Jeep J-4500. Most bearings are cast with lubrication channels, so very little friction is created around the engine main bearings and they will last the life of the vehicle.
