What does the '0.25' size designation mean for these bearings?

The '0.25' in the part number indicates that these bearings are 0.025 inches undersize. This means they are intended for use when the engine block's bearing bores have been machined down to accommodate this specific clearance, often during an engine rebuild.

Why are camshaft bearings important in an engine rebuild?

Camshaft bearings are critical because they support the camshaft and ensure it spins freely with minimal friction. They also play a vital role in maintaining proper oil pressure and lubrication to the valvetrain. Using the correct, well-made bearings is essential for the longevity of your engine rebuild.

What is the typical application for these bearings?

These camshaft bearings are typically used during a complete engine rebuild or overhaul for Ford 4.6L and 5.4L 2-valve OHC engines. They are a direct replacement for worn or damaged original bearings.

About this part

Product Details

King Engine Bearings is well-known for making solid engine components, and these camshaft bearings for Ford 4.6L and 5.4L 2-valve OHC engines are no exception. If you're rebuilding the top end of one of these Ford modular engines, getting the camshaft bearings right is crucial for proper oil flow and long-term engine health. These bearings are designed to fit precisely into the block, ensuring the camshaft spins smoothly and stays properly aligned.

This particular set is sized 0.025 inches undersize, which is important to note if you're working with a block that has been machined or requires specific clearances. Using the correct size bearing is key to achieving the intended oil pressure and preventing premature wear on both the bearings and the camshaft journals. King uses a specialized material and manufacturing process to create bearings that handle the demands of an engine rebuild.
