What is the purpose of main bearings?

Main bearings support the crankshaft within the engine block. They allow the crankshaft to rotate smoothly while maintaining precise alignment, which is essential for proper engine operation and longevity.

What does 'flanged bearing thrust' mean?

Flanged bearing thrust refers to a specific design that helps control the axial (fore-and-aft) movement of the crankshaft. This prevents the crankshaft from moving too far in either direction within the engine block.

Are these bearings a direct replacement for the original Ford parts?

Yes, these ACL main bearings are designed as a direct replacement for the original equipment on the specified 1983-1992 Ford Ranger V6 models. Always refer to your vehicle's service manual for correct installation procedures.

Product Details

When you're rebuilding or refreshing the engine in your 1983-1992 Ford Ranger, especially if you've got the V6 under the hood, getting the crankshaft main bearings right is crucial. These ACL main bearings are built to handle the demands of your engine, ensuring the crankshaft spins smoothly and stays properly aligned. They're designed to replace your old, worn-out bearings, which can cause all sorts of noise and performance issues if they fail.

This set includes flanged bearing thrust, which is important for controlling the crankshaft's fore-and-aft movement. ACL uses well-built materials to create bearings that can withstand the constant friction and heat inside your engine. Getting these installed correctly is a key step in making sure your engine runs reliably for miles to come.
