American Motors Spirit Main Bearing Set

Keeping your Spirit in top shape is your top priority.

When your American Motors Spirit was born, it was destined for a driver who prioritizes long-lasting quality in their automobile. You purchased your Spirit because its reliability and versatility struck a chord inside you; so why would you be okay with second best when it comes to the highest quality auto parts? While it may not be difficult to buy replacement parts for American Motors vehicles, these days only the absolute best are required to fix your automobile. Anyone who drives a American Motors knows that when it comes to fixing their car, truck, or SUV only the absolute best replacement parts will do.

The function and purpose of Main Bearing Set.

Your engine can totally break down from lack of lubrication; resulting in intense friction and heat. The places where the most rotary movement occurs in your engine are where the crankshaft spins through the main bore, which is why you will find your American Motors Spirit main bearings 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 American Motors Spirit. When properly lubricated, friction and heat are minimized as the main bearings protect your internals for, hopefully, the life of your car or truck.
