What does '.01mm Oversized' mean for these main bearings?

This means the bearings are manufactured to be 0.01 millimeters smaller in diameter than standard. They are intended for use when the crankshaft journals have been machined down by 0.01mm during a rebuild to remove imperfections or wear.

What vehicles does this ACL main bearing set fit?

This set is designed for a range of 1965-2000 Chevrolet models like the C10, C2500 Suburban, C3500, Camaro, Chevelle, Corvette, and Impala, as well as the Excalibur Phaeton, all equipped with V8 396, 402, 427, or 454 engines.

Are these bearings suitable for a stock, unmachined crankshaft?

No, these bearings are specifically .01mm undersize. They are intended for use with a crankshaft that has been professionally ground down by 0.01mm. Using them on a standard crankshaft will result in excessive oil clearance and potential engine damage.

Product Details

When you're rebuilding or refreshing a classic Chevy V8, especially those big blocks like the 396, 402, 427, or 454, getting the main bearings right is crucial for engine health. These ACL main bearings are precisely .01mm undersize, which is exactly what you need if your crankshaft journals have been ground down by .01mm during a rebuild. Using the correct undersize bearing ensures proper oil clearance, which is vital for lubricating the crankshaft and preventing premature wear. ACL is a well-known name in engine bearings, and this set is built to meet the demands of these powerful V8s.

This set includes all the main bearings you'll need for your engine rebuild. Make sure to check your crankshaft's specifications to confirm if the .01mm undersize is the correct fit for your application. Proper installation and oiling are key to getting the most out of these bearings.
